DETAILED DESCRIPTION OF THE INVENTION

[0039] The automated orbital machine for cutting and drawing the pipe preservation system (PPS), according to the present invention is directed, preferably, to carbon steel pipes, externally coated and with their ends protected by the preservation system of pipes (PPS), as described in the process of patent BR 102019015918-9 A2, called the PPS system or PPS.

[0040] The automated orbital machine for cutting and drawing the pipe preservation system (PPS), according to a preferred embodiment of the present invention, can be used in pipeline systems, submarine or submerged pipelines and onshore pipelines, which are used in the field of oil, gas, mining, sanitation, water supply and others, which use carbon steel pipes externally coated in three layers of polyethylene or polypropylene, and subsequent removal from the pipe preservation system (PPS).

[0041] FIG. 1 represents a sectional view of the pipe preservation system (PPS), as described in BR 102019015918-9 A2, applied to a pipe. FIG. 1 illustrates the pipe preservation system (PPS) comprising a cup 1.1, a seal 1.2, a cover 1.3 and a pipe external coating 1.4.

[0042] FIG. 1 also illustrates a cutting position 1.5, a chamfer angle β of the collar (cutback), wherein the angle β is less than 30° (β<30°), a bevel 1.6, a pipe wall 1.7, an outer flap length A, 1.8 of the cup 1.1, the collar (cutback) length (C), 1.9, an FBE exposure band (FBE tail) width (T), 1.10, a pipe wall thickness eP, 1.11, a pipe external coating total thickness eR, 1.12, a pipe outer diameter DE, 1.13 and a pipe inner diameter DI, 1.14.

[0043] The outer diameter range of the pipe DE, 1.13 of externally coated carbon steel pipes, preferably, is from 114.3 mm to 609.6 mm (4½ to 24 inches).

[0044] The pipe wall thickness range eP, 1.11, of externally coated carbon steel pipes, preferably, is from 6.35 mm to 50.8 mm (¼ to 2 inches).

[0045] The external coating total thickness eR, 1.12 of the three-layer polyethylene pipe or three-layer polypropylene pipe of the pipe preservation system (PPS), according to a preferred embodiment of the present invention, is in the range of 1.6 mm to 10 mm.

[0046] The positioning of the cutting machine of the present invention to perform the cut, preferably, is a function of the length of the external flap A, 1.8 of the cup 1.1 of the pipe preservation system (PPS).

[0047] More specifically, the cut does not damage the pipe preservation system (PPS) cup 1.1, allowing its reuse. All components of the pipe preservation system (PPS), after cutting, can be reused and/or recycled.

[0048] FIG. 2 represents a collar (cutback) 2.2 of a pipe 2 externally coated in three layers (3-layer coating). In detail, FIG. 2 illustrates pipe 2, the collar (cutback) 2.2, an FBE exposure band (FBE tail) 2.3, a collar (cutback) chamfer 2.4, an angle β of the collar (cutback) chamfer 2.4, wherein β is less than 30° (β<30°), a pipe external coating 1.4, the length of the collar (cutback) (C), 1.9, and an FBE exposure band (FBE tail) width (T), 1.10.

[0049] With respect to the chamfer of the collar (cutback) 2.4, after the cut performed by said machine 100 of the present invention, preferably, this must have an angle β in relation to the surface of the pipe 2 less than 30° (β<30°), this being an essential condition for chamfering, with a tolerance of +0-2°. Additionally, the collar (cutback) chamfer 2.4 must have a smooth, even surface.

[0050] The execution of the collar chamfer 2.4 by cutting, proposed by the machine 100 of the present invention, guarantees a uniform and stress-free surface in the coating system, favoring the preservation and anti-corrosion protection. Cutting is carried out before installing the pipe in the field or at sea, with enough time for the layers to settle and there are no more residual stresses. Bevel 1.6 and collar 2.2 will only be exposed for the time necessary for coupling, welding and inspection, ensuring their protection and integrity until the application of the definitive anti-corrosion protection system. The use of a sander, grinder, wire brush or any other means of preparing the joint for welding is eliminated, as the bevels 1.6 and collars 2.2 will be made available, after cutting and drawing the pipe preservation system (PPS), within the specified standards, without the need for any adjustment or additional preparation.

[0051] The length of the collar (cutback) (C), 1.9 is specified in Standards ABNT NBR 15221-1 (polyethylene in three layers) and ABNT NBR 15221-2 (polypropylene in three layers), which dictates a length of 120 mm±10 mm. However, the buyer can specify shorter or longer lengths, maintaining a tolerance of ±10 mm. Specifically, the automated orbital machine for cutting and drawing the pipe preservation system (PPS) 100 of the present invention is capable of cutting the collar with a length (C), 1.9 with a tolerance preferably of ±5 mm in the specified length, contributing for greater dimensional accuracy, favoring the effectiveness of the field joint coating process.

[0052] The FBE exposure band 2.3 is performed simultaneously with the cut, which is done without generating non-recyclable waste, favoring the environmental issue.

[0053] In addition, after cutting, the width of the FBE exposure band (FBE tail) (T), 1.10, when specified by the buyer, must be performed by removing the entire layer of copolymer adhesive (second layer of the external coating of the pipe) without causing damage to the FBE, in the specified width (T), 1.10. The width of the FBE exposure band (T), 1.10, is a function of the width of the cutting blade, the sharpening angle of the cutting blade, the angle β of the chamfer of the collar and the lead angle of the cutting blade, being in the 1 mm to 10 mm range per cut, preferably. The width of the FBE exposure band (T), 1.10, obtained by cutting with the automated orbital machine for cutting and drawing the pipe preservation system (PPS) 100 is preferably 1 mm to 10 mm. The width tolerance of the FBE exposure band (T), 1.10, is preferably within the range of 1 mm to mm and 5 mm to 20 mm. Furthermore, the width of the FBE exposure band (T), 1.10, is inversely proportional to the total thickness of the pipe external coating.

[0054] FIG. 3 represents the automated orbital machine for cutting and drawing the pipe preservation system (PPS) 100, in the position to fit into the end of the pipe, according to a preferred embodiment of the present invention.

[0055] According to a preferred embodiment of the present invention, as illustrated in FIG. 3, the automated orbital machine for cutting and drawing the pipe preservation system (PPS) 100 comprises at least one lifting support 7.1, at least one lifting eye 7.2, at least one pipe preservation system (PPS) cutting device 7.3, at least one cutting lever driving piston 7.4, at least one support wheel 7.5, preferably at least two support wheels 7.5, at least one column 7.7, at least one emergency stop button 7.8, at least one support arm rotation device 7.9, at least one fitting disc rotation device 7.10, at least one cage rotation device 7.11, at least one support arm 7.12, at least one cage rotation device 7.13, at least one cage front disc 7.14, at least one fitting disc 7.15, at least one fitting device 7.16, at least one bar 7.17, and at least one cage rear disc 7.18.

The hydraulic arm must have safety locks to maintain its position during cutting operations.

[0060] In the example of construction and installation of subsea pipelines, the automated orbital machine for cutting and drawing the pipe preservation system (PPS) 100 is moved by a crane, coupled to at least one lifting eye 7.2, wherein the crane is suspended from the vessel or base onshore. In this condition, the alignment is favored both in relation to the floor, which, as a rule, is regular and leveled, as well as in the positioning of the pipe, which is also leveled. The crane must have safety locks to maintain positioning during the cutting operations.

[0061] The automated orbital machine for cutting and drawing the pipe preservation system (PPS) 100, including the hydraulic arm or crane used in lifting and moving the machine 100, are operated by wired or wireless remote control, for the safety of the operator, who must stay at a distance of at least 2 (two) meters from the machine while it is in operation.

[0062] The automated orbital machine for cutting and drawing the pipe preservation system (PPS) 100, also preferably, can comprise a security system, with at least one sensor, such as an approximation sensor, which restricts the area within a radius of 2 (two) meters, through an electronic barrier, around its perimeter, when in operation.

[0063] In particular, an embodiment of the pipe preservation system (PPS) cutting device 7.3 is described in detail and claimed in patent process BR102022007711-8.

[0064] Specifically, according to the preferred embodiment of FIG. 3, the pipe preservation system (PPS) cutting device 7.3 is attached to at least one bar 7.17.

[0065] The cutting lever driving piston 7.4 can be, preferably, a hydraulic or pneumatic piston. More preferably, the cutting lever driving piston 7.4 can be actuated by a central hydraulic or compressed air pumping unit. The cutting lever driving piston 7.4 allows the cutting blade 3.5 to be inserted easily, firmly and safely. The cutting lever 3.4 is attached to, preferably, threaded in the pipe preservation system (PPS) cutting device 7.3 both in the front part and in the rear part of the same, allowing the cut to be made both in the clockwise and counterclockwise directions.

In particular, the entire alignment system for cutting operations, execution of the FBE exposure band (FBE tail), will be based on the position of the pipe mouth, through the fitting disc 7.15.

[0074] The cage rotation device 7.13, preferably, can be made of laminated carbon steel.

[0075] In addition, the cage rotation device 7.13 aims at rotating the cage front disc 7.14. The cage rotation device 7.13 is supported on at least one cage rotation device bearing 8.7 installed on the outer surface of the structural guide pipe 8.8. The coupling of the cage rotation device shaft 7.11 with the cage rotation device 7.13 is done by gears or pulleys with “V” or toothed belts.

[0076] FIG. 5A represents a front view of the cage 9, comprising, the cage front disc 7.14, a central hole 9.2 in the cage front disc 7.14, a plurality of holes of the cage rotation device 9.3 for attachment elements, such as screws, and a plurality of holes for connection to the bar 9.4.

[0077] FIG. 5B shows a side view of the cage 9, where the at least one cage front disc 7.14 and the at least one rear disc of the cage 7.18 are installed on at least one bus 7.17. Furthermore, it is possible to observe a plurality of holes 9.5 in the bars 7.17 for installing at least one support wheel 7.5.

[0078] FIG. 5C shows a sectional view A-A, which is shown in FIG. 5B, showing the rear disc of the cage 7.18.

[0079] Preferably, the cage front disc 7.14 can be made of laminated carbon steel or aluminum. The central hole 9.2 of the cage front disc 7.14 serves to leave the fitting disc shaft 8.3 free.

[0080] The holes in the cage rotation device 9.3 serve to fit connecting means, such as screws, to receive the cage rotation device 7.13.

[0081] Preferably, the cage rear disc 7.18 can be made of laminated carbon steel or aluminum.

[0082] Bars 7.17, preferably, can be manufactured in extruded aluminum or in hollow square profile of laminated carbon steel.

[0083] According to a preferred embodiment of the invention, the cage is dismountable and it is only necessary to loosen and remove screws that are inserted into the holes for connection to the bar 9.4.

[0084] The cage is rotated by the cage rotation device 7.13.

[0085] FIG. 6A represents a side view of the fitting device 7.16, which comprises at least one fitting disc 7.15, at least one fitting cylinder 10.2 and at least one link tie rod 10.4, preferably two link tie rods 10.4. Also, in FIG. 6A, a pipe preservation system (PPS) cover 1.3 is illustrated.

[0087] Particularly, the pipes to be cut by the automated orbital machine for cutting and drawing the pipe preservation system (PPS) 100 may have the same outer diameter, DE, 1.13, but with different wall thicknesses eP, 1.11. Consequently, the inner diameter of the pipe preservation system (PPS) cup 1.1 and the outer diameter of the pipe preservation system (PPS) cover 1.3 must be specific to each wall thickness, eP, 1.11, of the pipe to be cut. Based on this premise, a fitting cylinder 10.2 is manufactured (machined, for example) for each wall thickness, eP, 1.11, of the pipe, since this component forms a set with the cover 1.3 of the pipe preservation system (PPS). Furthermore, for this same reason, the tie rods 10.4 are positioned in such a way on the fitting disc 7.15 that it is possible to install the pipe preservation system (PPS) cover 1.3 and the fitting cylinder 10.2 for any wall thickness, eP, 1.11, of the pipe in the range of 6.35 mm to 50.8 mm (¼ to 2 inches), for example, loosening only the attachment nuts of the tie rods 10.4. In this way, the only components that need to be modified, depending on the wall thickness of the pipe eP, 1.11, are the fitting cylinder 10.2 and the pipe preservation system (PPS) cover 1.3, resulting in practicality and economy.

[0088] The fitting device 7.16, according to a preferred embodiment of the present invention, can be made of laminated carbon steel. Furthermore, the fitting device 7.16 preferably has at least one hole 10.41 for installing the link tie rods 10.4 and a flange 10.5 for fitting into the fitting disc shaft 8.3.

[0089] The fitting cylinder 10.2, preferably, can be manufactured from the same polymeric material as the pipe preservation system (PPS) cover 1.3, creating an assembly. In addition, the fitting cylinder 10.2 and the pipe preservation system (PPS) cover 1.3 are joined, for example, by four tie rods 10.4, which are attached to the fitting disc 7.15.

[0091] The fitting disc 7.15 and the fitting device 7.16 are attached, preferably screwed onto the fitting disc shaft 8.3.

[0092] FIG. 7 represents the front view of the pipe preservation system (PPS) cutting device 7.3 with at least one cutting blade 3.5 in the retracted position, according to a preferred embodiment of the present invention. The pipe preservation system (PPS) cutting device 7.3 further comprises a body 3.1, a fitting guide 3.2, at least one cutting lever 3.4, at least one cutting blade receptacle 3.6, and at least one support structure 300. In addition, FIG. 7 shows an external coating 1.4 of the pipe to be cut, an outer flap of the pipe preservation system (PPS) cup 3.8, a pipe wall 1.7 and a FBE layer 3.12. Further, FIG. 7 shows bus 7.17.

[0093] The pipe preservation system (PPS) cutting device 7.3, according to the preferred embodiment in FIG. 7, has at least one cutting blade 3.5 in the retracted position; the cutting blade receptacle 3.6 in a fully retracted position; and the cutting lever 3.4 in the retracted position with an angle of 0° in relation to the body 3.1.

[0094] The bar 7.17, preferably, can be made of extruded aluminum or a square profile of hollow laminated carbon steel, and is the structural element to keep the pipe preservation system (PPS) cutting device 7.3 attached and its parallelism with respect to the surface of the pipe 2. The bar 7.17 preferably comprises a graduated scale for positioning the pipe preservation system (PPS) cutting device 7.3 precisely, wherein the scale can be provided with graduations in millimeters.

[0095] The cutting blade receptacle 3.6, preferably, can be manufactured in laminated carbon steel. The cutting blade receptacle 3.6 can be articulated by moving the cutting lever 3.4, wherein the cutting blade receptacle 3.6 can be positioned from 0° to 90°. More specifically, the cutting blade receptacle 3.6 is arranged in a retracted position with the cutting lever 3.4 at an angle of 0° parallel to the body 3.1, or the cutting blade receptacle 3.6 is arranged in a cutting position with cutting lever 3.4 at an angle of 90° perpendicular to body 3.1.

[0096] The cutting blade receptacle 3.6 can house at least one cutting blade 3.5 in both the left and right positions, and is therefore adaptable for both clockwise and counterclockwise rotation. Furthermore, the cutting blade receptacle 3.6 has one or more attachment means of the cutting blade 3.5 and can be adjusted for cutting blades 3.5 from 3 mm to 12 mm thick and from 10 mm to 25 mm wide, for example.

[0097] The one or more attachment means can be any commonly used attachment means or the combination of more than one attachment means, such as at least one of or a combination of screws, screws with or without washers or nuts, rivets, pins, keys.

[0098] According to the preferred embodiment illustrated in FIG. 7, the cutting blade receptacle 3.6 may already be adjusted for the collar chamfer angle β equal to 29°, but it can be customized for other angles, between 25° and 29°, for example, if needed.

[0099] Especially, preferably, the at least one support structure 300 includes at least one support wheel 7.5 and at least one support wheel control device 3.11.

[0100] Preferably, the support wheel 7.5 has the running part in polymeric material so as not to damage the external coating to be cut. Specifically, the support wheel 7.5 serves as a support element for the bus 7.17 and to maintain the correct distance of the pipe preservation system (PPS) cutting device 7.3 in relation to the outer surface of the pipe coating to be cut.

[0101] The support wheel control device 3.11 is preferably connected to a pneumatic control that equalizes the pressure on the support wheels 7.5, preferably four support wheels 7.5, in order to keep the bar 7.17 equidistant from the outer surface of the pipe. Furthermore, the support wheel control device 3.11 includes an electromagnetic command that allows positioning the support wheel 7.5, parallel (according to FIG. 7) or perpendicular (according to FIG. 8), to the bar 7.17. The support wheel control device 3.11 can be at least one or the combination of: pneumatic or hydraulic piston, springs, leaf spring, or resilient material.

[0102] The fitting guide 3.2 can be coupled to a pneumatic piston to adjust its positioning automatically depending on the length of the collar (C), 1.9. The length of the collar (C), 1.9 is a variable, which is preferably controlled by a computer program (software) of an automated system and has as reference the zero point, which is the front disc face of the cage 7.14. This feature is additionally useful for multiple cuts serving as a cutting line advance device.

[0103] The cutting blade 3.5 is made of laminated or forged carbon steel, with the faces (edges) to be sharpened and hardened, according to a preferred embodiment. Particularly, the length of hardening of the cutting edge of the external coating of the pipe is 25 mm at most. The thickness of the cutting blade 3.5 is from 3 mm to 12 mm, depending on the thickness and the type of coating to be cut, preferably. The width of the cutting blade 3.5 is 6 mm to 25 mm preferably. The sharpening angle of the cutting blade 3.5 is defined according to the best cutting performance, being in the range of 15° to 35°, preferably. The lead angle of the cutting blade 3.5 is defined according to the difficulty of penetrating the cutting blade 3.5 into the coating of the pipe to be cut, being in the range of 30° to 90°, preferably. The edge sharpening angle of the FBE exposure band is greater than or equal to the cutting blade inclination angle β. The width of the FBE exposure band (T), 1.10, is a function of the width of the cutting blade, the sharpening angle of the cutting blade, the angle β of the chamfer of the collar and the lead angle of the cutting blade, being in the 1 mm to 10 mm range per cut, preferably.

[0104] Additionally, the cutting blade 3.5 can be heated by electrical resistance, electromagnetic induction, infrared or another heat source, except by flame, in order to facilitate penetration and increase the cutting speed, according to the preferred embodiment of the present invention. The temperature range, minimum and maximum, is defined according to the material of the pipe coating to be cut. The heated cutting blade 3.5 can only touch the external coating of the pipe during turning; therefore, it must be retracted before the machine stops turning, to prevent the generated heat from damaging the finish of the chamfer of the collar 2.4. The maximum temperature is preferably 10% below the softening temperature (VICAT) of the third layer of the coating to be cut, which for polyethylene (PE) is 115° C. and for polypropylene (PP) is 145° C., according to the table S.3, of the ABNT NBR 15221-1 and ABNT NBR 15221-2 standards, respectively. Based on this premise, the temperature of the cutting blade cannot be higher than 100° C. for polyethylene and 130° C. for polypropylene.

[0105] The cutting blade 3.5 can be made using commercial materials, available in abundance in the market, such as standardized blades for stilettos, wood chisels and cutting tools for lathes, since the coatings are made of polymeric material, as preferably described in the present description, but not limitingly, polyethylene and polypropylene.

[0106] More specifically, the end of the outer flap of the cup 3.8, acts as a cutting facilitator, since it is not adhered to the surface of the pipe, allowing the end of the cutting blade 3.5 to lift the coating in this region, propagating along the along the circumference of the pipe.

[0107] FIG. 8 represents a front view of the pipe preservation system (PPS) cutting device 7.3 with the cutting blade 3.5 in the cutting position, wherein the cutting blade 3.5 is arranged in a cutting position with an angle β less than 30° in relation to the surface of pipe 2, in the longitudinal direction; more particularly, the angle β is equal to 29° (β=29).

[0108] The pipe preservation system (PPS) cutting device 7.3, represented in FIG. 8, comprises at least one coupling 4.1 for receiving a compressed air hose, for example, for the support wheel control device 3.11.

[0109] The support wheel control device 3.11 has an electromagnetic command that allows positioning the support wheel 3.11 parallel (as in FIG. 7) or perpendicular (as in FIG. 8) to the bar 7.17.

[0110] FIG. 9 is a side view of the pipe preservation system (PPS) cutting device 7.3 with the cutting blade 3.5 in the retracted position. According to FIG. 9, the pipe preservation system (PPS) cutting device 7.3 comprises at least one cutting position setting means 5.5 and at least one adjustment mechanism 5.10.

[0111] The pipe preservation system (PPS) cutting device 7.3 is attached to the bus 7.17, through at least one cutting position setting means 5.5. Preferably, the cutting position setting means 5.5 is a screw, but it can be any setting means such as at least one or the combination of: any type of screw, screw with or without washers or nuts, rivets, pins, keys.

[0112] The at least one cutting position setting means 5.5 is preferably made of laminated carbon steel. Furthermore, the at least one cutting position setting means 5.5 is installed on the rear part of the fitting guide 3.2 and serves to attach the same to the bar 7.17.

[0113] The at least one adjustment mechanism 5.10 serves to keep the cutting blade 3.5 pressed, on the FBE layer without removing it or damaging it during the cut, and to cushion the impacts during the rotation of the cutting machine 100. Preferably, the at least one adjustment mechanism 5.10 can be at least one carbon steel spiral spring, preferably with dimensions and coefficient k designed not to damage the FBE layer 3.12. Particularly, the number of springs can vary from one to six, for example. Optionally, the adjustment springs can be replaced by an air pocket connected to the central compressed air system, wherein the air pressure in the pocket will be calibrated to keep the cutting blade 3.5 pressed, but not to damage the FBE layer 3.12. In particular, the at least one adjustment mechanism 5.10 can be at least one of or the combination of: spiral spring; an air pocket controlled by an automated air pressure control system; leaf spring; and resilient material, for example.

[0114] Furthermore, FIG. 9 shows the cutting blade 3.5 in a retracted position with the cutting lever 3.4 at an angle of 0°, parallel, with respect to the body 3.1 and the cutting blade receptacle 3.6 in a fully retracted position with an angle of 0°.

[0115] FIG. 10 represents a side view of the pipe preservation system (PPS) cutting device 7.3 with the cutting blade 3.5 in a cutting position with the cutting lever 3.4 at a 90° angle to the body 3.1; and wherein the cutting blade receptacle 3.6 is fully lowered, in a cutting position, at the full depth of cut. Furthermore, FIG. 10 also represents the at least one adjustment mechanism 5.10 and the cutting lever 3.4 in the cutting position.

[0116] The cut starts with the cutting blade 3.5 facing the external coating of the pipe 1.4 and, as the machine turns, the depth is increased until the cutting blade 3.5 touches the FBE layer 3.12, peeling off the second layer of copolymer adhesive. Therefore, the cut must overlap the initial area to ensure that the entire layer of adhesive over the FBE exposure band is removed and that the full depth of cut is achieved around the entire circumference of the pipe, allowing the drawing of the pipe preservation system (PPS).

[0117] In some cases, depending on the thickness and material of the pipe external coating, it may be necessary to cut in two or more steps to obtain the specified width of the FBE exposure band (T), 1.10. In this case, from the second step, one external coating ring will be generated per step. This ring will be destined for recycling in consonance with the objectives of environmental care, provided for in the pipe preservation system (PPS).

[0118] In this sense, in order to prevent excessive pressure from the cutting blade 3.5 on the FBE from resulting in peeling thereof, the pipe preservation system (PPS) cutting device 7.3 has at least one adjustment mechanism 5.10 to keep the cutting blade 3.5 pressed during the cut and to cushion the impacts when the cutting machine rotates, adjusting to and following the imperfections of the pipe surface and any ovality existing in the pipe, cushioning the shocks. A factor that cooperates is the fact that the FBE layer is smooth and cohesive, favoring the peeling process of the second layer of copolymer adhesive, generally having a minimum thickness of 200 μm (0.2 mm), both for the coating in three layers of polyethylene as for the three-layer coating of polypropylene. The FBE layer (first layer) has a thickness of 250 μm−100 μm+100 μm (0.15 mm to 0.35 mm).

[0119] FIG. 11 represents a sectional view of the automated orbital machine for cutting and drawing the pipe preservation system (PPS) 100, during the cutting operation, according to a preferred form of the present invention.

[0120] In addition, FIG. 11 shows the cutting lever driving piston 7.4 in the cutting position, the fitting disc rotation device 7.10, at least one support arm 7.12 resting on the ground, the at least one cage rotation device 7.13, the fitting disc 7.15, the fitting device 7.16 and the at least two support wheels 7.5.

[0121] The automated alignment for cutting is done through the fitting disc 7.15, which must be flush with the end of the cup 1.1 of the pipe preservation system (PPS), as represented in FIG. 11. As soon as the alignment is established, a reference positioning device, installed in the hardware of an automation system of the machine 100 of the present invention, registers and locks the coordinates x, y and z, establishing the configuration (setup). The x, y and z coordinates become the reference for the entire system. Subsequently, the support wheels 7.5 are turned, automatically, by an electromagnetic mechanism, to the position represented in FIG. 11 and are adjusted, automatically, based on the reference of coordinates x, y and z, so that the four bars 7.17 are at the same distance from the pipe coating surface, through at least one distance sensor that sends at least one command to the support wheel control device 3.11, wherein the support wheel control device 3.11 can be at least one pneumatic piston on the shaft of the support wheels 7.5. This same procedure is adopted in relation to at least one support arm 7.12, preferably at least two support arms 7.12, which are rotated and driven until they touch the ground, through at least one support arm rotation device 7.9, as an electric motor 7.9, until the support arm rods 7.12 touch the ground, as shown in FIGS. 11, 12 and 14, obeying the reference positioning system established in the setup. In this way, the cut can be performed precisely.

[0122] The fitting disc 7.15 is coupled and rotates together with the fitting disc shaft 8.3, which rotates clockwise or counterclockwise through a gear, as represented in FIG. 11, or by a “V” or toothed belt.

[0123] As identified in FIG. 11, the distance between the pipe and the ground is preferably at least 600 mm.

[0124] FIG. 12 represents the side view of the automated orbital machine for cutting and drawing the pipe preservation system (PPS) 100, according to a preferred embodiment of the present invention, during the cutting operation.

[0125] In a complementary way, FIG. 12 illustrates the column 7.7, the cage front disc 7.14, the fitting disc 7.15, the fitting disc rotation device 7.10, at least one motor of the fitting disc rotation device 12.5, at least one support arm rotation disc 12.6, the horizontal lifting support bar 7.1 with lifting eyes 7.2, the emergency stop button 7.8, at least one support arm rotation motor 7.9, at least one cage rotation motor 12.10 and support arms 7.12.

[0126] The fitting disc shaft 8.3 is coupled to at least one electric motor of the fitting disc rotation device 12.5, by gears or by “V” or toothed belts, and rotates both clockwise and counterclockwise. The electric motor of the fitting disc rotation device 12.5 includes variable rotation, instant stop mechanism and torque adjustment, for example.

[0127] The at least one motor of the fitting disc rotation device 12.5 rotates the fitting device 7.16 and has variable speed, rotation reversal and adjustable torque.

[0128] The connections of the hydraulic oil and compressed air hoses for feeding the automated orbital machine for cutting and drawing the pipe preservation system (PPS) 100 are preferably made by quick couplings 4.1 installed in column 7.7, the same occurring with power supply and wired network. The entire cabling system, hoses and piping used in the automation system can be designed and detailed according to the project specifications.

[0129] The compressed air hoses and electrical, command and drive cables, which are connected to the automated devices installed on the bars 7.17, are wound and uncoiled on the cage rotation device 7.13, which has a sensor that interrupts the turning if they roll up or unroll completely. Preferably, the length of the hoses and cables allows for two complete turns.

[0130] FIG. 13 represents the automated orbital machine for cutting and drawing the pipe preservation system (PPS) 100, according to a preferred mode of the present invention, after cutting and drawing the pipe preservation system (PPS).

[0131] In addition, FIG. 13 illustrates the cutting lever driving piston 7.4, the bevel 1.6 and collar 2.2 of the pipe exposed for inspection and the pipe preservation system (PPS) drawn 13.3.

[0132] As soon as the cut is finished, the cutting lever driving piston 7.4 positions the cutting lever 3.4 in the retracted position, as shown in FIG. 13. In sequence, the drawing of the pipe preservation system (PPS) is done through lifting eyes 7.2, finalizing the operation, leaving bevel 1.6 and collar 2.2 exposed for inspection.

[0133] FIG. 14 depicts a sectional view of the automated orbital machine for cutting and drawing the pipe preservation system (PPS) 100, during the cut of the pipe preservation system (PPS) on a ramp, in accordance with a preferred embodiment of the present invention.

[0134] According to FIG. 14, a lifting hook positioned on the right eye 7.2 is illustrated, the angle φ of adjustment of the support arms and one of the support arms 7.12 positioned according to the inclination angle φ of the ramp, where, in this preferred embodiment, the inclination angle φ of the ramp is less than or equal to 15° (φ≤15°).

[0135] The support arm rotation device 7.9 aims at positioning the support arms 7.12 in order to compensate the inclination angle φ of the pipe, as shown in FIG. 14.

[0136] The support arm rotation device 7.9 consists of an electric motor 7.9 coupled through gear to a support arm rotation disc 12.6 that is connected to another support arm rotation disc 12.6, through the support arm rotation device shaft 8.5.

[0137] The upper supports of each of the support arms 7.12 are attached to each of the support arm rotation discs 12.6.

[0138] Regarding the actuation of the support arm rotation device 7.9, this can be automated, connected to the machine reference positioning system; or manually, by the operator, through a remote-control panel (wired or via wireless connection). For example, for manual actuation, the operator must use a clinometer to measure the angle φ of inclination of the pipe, which will have its coating cut, in a display of a control panel, by entering the value of the angle φ, causing the support arm rotation device 7.9 rotate the support arm rotation discs 12.6, so that the support arms 7.12 are positioned as represented in FIG. 14. The pipe inclination angle φ is limited to 15°, for safety reasons, according to that preferred embodiment of the present invention.

[0139] The automated orbital machine for cutting and drawing the pipe preservation system (PPS) 100, according to a preferred form of the present invention, may have stored, in a supervisory system connected to the same (remotely or wired), the parameters of the cutting and manufacturing operations of the FBE exposure band 2.3, wherein such parameters include at least one or the combination of, but are not limited to: rotation and feed speed of the cutting lever 3.4. Specifically, the feed speed parameter of the cutting lever 3.4 until full depth of cut is reached. Furthermore, the parameter may be the position for retracting the cutting blade 3.5 at the end of the operation, which will also determine the retraction of the support arms 7.12 and the moment for drawing the pipe preservation system (PPS) through the hoisting support 7.1, for example.

[0140] The technique adopted by the automated orbital machine for cutting and drawing the pipe preservation system (PPS) 100 of the present invention, preferably, starts from the end of the outer flap of the cup 3.8 of the pipe preservation system (PPS) and encompasses three activities: the first, cut the external coating of pipe 1.4 in order to obtain a chamfer on the collar 2.4 with an angle β less than 30°; the second, make the FBE exposure band 2.3 simultaneously, quickly and accurately; and the third, to perform a quick drawing of the pipe preservation system (PPS), in the pipe bed, in the vessel or in the base on land. More specifically, the end of the outer flap of the cup 3.8 acts as a cutting facilitator, since it is not adhered to the surface of the pipe, allowing the end of the cutting blade 3.5 to lift the coating in this region, propagating along the circumference of the pipe.

[0141] According to a preferred embodiment of the present invention, the beginning of the cut, using an automated orbital machine for cutting and drawing the pipe preservation system (PPS) 100, is done through the cutting lever 3.4, which moves the cutting blade 3.5 against the external coating of the pipe 1.4, gradually deepening, while the machine 100 rotates, until it touches the FBE layer (first layer) 3.12 (observed in FIGS. 7, 8, 9 and 10), using it as a support. The actuation of the cutting lever 3.4 is done through the cutting lever driving piston 7.4, which can be a pneumatic piston. As soon as the cutting blade 3.5 touches the FBE layer (first layer) 3.12, the system of the machine 100 is locked until the cut is finished (as shown in FIG. 11). When the cut is finished, the cutting lever driving piston 7.4 positions the cutting lever 3.4 in the retracted position (as shown in FIG. 13) and the drawing of the pipe preservation system (PPS) is carried out through the lifting eyes 7.2, leaving the bezel 1.6 and the collar 2.2 exposed for inspection (as shown in FIG. 13).

[0142] In some cases, depending on the thickness and material of the external coating of the pipe, it may be necessary to cut in two or more steps to obtain the specified FBE exposure band width (T), 1.10. In this case, from the second step, one external coating ring will be generated per step. This ring will be destined for recycling in consonance with the objectives of environmental care, provided for in the pipe preservation system (PPS).

[0143] The cutting speed of the automated orbital machine for cutting and drawing the pipe preservation system (PPS) 100, according to a preferred embodiment of the invention, is a function of the material and thickness of the external coating of the pipe.

[0144] The cutting blade 3.5 is easily replaced with a sharpened or new one.

[0145] The sharpening angle of the cutting blade and the lead angle make it possible to cut without tearing, fraying, vitrifying, wrinkling or making the external coating of the pipe becoming a paste, following a uniform line along its circumference, that is, the finish of the cut results in a uniform and clean surface, maintaining the original features of the coating applied to the pipe, being superior to the finish generated in brushing.

[0146] In another preferred way, the alignment of the automated orbital machine for cutting and drawing the pipe preservation system (PPS) 100 can be done by the operator, if said machine does not have a reference positioning device. In this case, the operator must position the fitting disc 7.15 facing the end (beak) of the cup 1.1 of the pipe preservation system (PPS), as shown in FIG. 11, and subsequently, manually drive the support arms 7.12 until they touch the ground, keeping the fitting disc 7.15 in the original position, as shown in FIG. 12. Subsequently, the command is activated to turn the support wheels 7.5 to the position represented in the Figure and check if the fitting disc 7.15 is in the correct position, making adjustments if necessary.

[0147] The applicability of the automated orbital machine for cutting and drawing the pipe preservation system (PPS) 100 of the present invention can be on static pipes. In the state of the art, existing means can only be applied to straight pipes that rotate during cutting.

[0148] The coupling of the automated orbital machine for cutting and drawing the pipe preservation system (PPS) 100 of the present invention is done in an unprecedented way, using the fitting of the cup 1.1 and the cover 1.3 of the pipe preservation system (PPS) for alignment, positioning of the cut and drawing of the pipe preservation system (PPS).

[0149] The depth of the cut is a function of the outer diameter of the pipe and the total thickness of the external coating of the pipe; therefore, the automated orbital machine for cutting and drawing the pipe preservation system (PPS) 100 of the present invention is calibrated with based on these parameters.

[0150] The automated orbital machine for cutting and drawing the pipe preservation system (PPS) 100, preferably, can have 3 three sizes S, S1 to S3, according to the nominal diameter DN of the pipe that will have its coating cut, which are: S1—DN 4 A 8, S2—DN 10 A 16 and S3—DN 18 A 24. These sizes will depend on the detailing of the project and will be approximately, the height×length c×width 1 in mm, S1: 600×700×500; S2: 1100×1200×900 AND S3: 1600×900×1400. For DN above 24, specific designs shall be developed.

[0151] The S1-Type automated orbital machine for cutting and drawing the pipe preservation system (PPS) indicated above is designed to be lightweight and compact so that its automation structure can be transported by a light vehicle (for example, a 4×4 vehicle) along the strip, for the construction and assembly of onshore pipelines, enabling its use in small pipelines.

[0152] The automated orbital machine for cutting and drawing the pipe preservation system (PPS) 100, preferably of the present invention is named according to its size S, being, for size S1: automated orbital machine for cutting and drawing the pipe preservation system (PPS) S1; for size S2, automated orbital machine for cutting and drawing the pipe preservation system (PPS) S2; and for size S3, automated orbital machine for cutting and drawing the pipe preservation system (PPS) S3.

[0153] The automated orbital machine for cutting and drawing the pipe preservation system (PPS) 100, according to a preferred embodiment of the present invention, uses the same structure for each size S (schedule) of nominal diameter DN of the pipe, except for the following components, which are specific to each pipe diameter: the cage, the fitting disc 7.15 and the fitting device 7.16. The cage is screwed onto the cage rotation device 8.6, the fitting disc 7.15 and the fitting device 7.16 are screwed onto the fitting disc shaft 8.3. All other components are common, including the pipe preservation system (PPS) cutting device 7.3, the cutting lever driving piston 7.4, the support wheels 7.5 and the bars 7.17.

[0154] The automated orbital machine for cutting and drawing the pipe preservation system (PPS) 100, according to the preferred embodiment of the present invention, is designed to use interchangeable parts, so that it is possible to transform the manual version into an automated one by adding the required fixtures, since several components are common to both versions.

[0155] Those skilled in the art in the technical field of mechanical engineering will value the knowledge presented here and will be able to reproduce the invention in the presented embodiments and in other variants, encompassed by the scope of the appended claims.
