DETAILED DESCRIPTION OF SELECTED SPECIFIC EMBODIMENTS
[0059] The novel features characteristic of the embodiments of the present application are set forth in the appended claims. However, the embodiments themselves and further objectives and advantages thereof, will best be understood by reference to the following detailed description when read in conjunction with the accompanying drawings, wherein:
[0060]
[0061] The pipe support system 100 first includes a pair of wedge blocks. These are denoted as a first wedge block 110a and a second wedge block 110b. Each wedge block 110a, 110b has an inside wall 114 and an outside wall 116. In addition, each wedge block 110a, 110b has an angled top surface 118. The top surfaces 118 slope inwardly from a top of the outside wall 116 to a top of the inside wall 114.
[0062] The wedge blocks 110a, 110b also offer end walls 112. Together, the end walls 112, the inside walls 114 and the outside walls 116 form a polygonal base for each of the respective wedge blocks 110a, 110b.
[0063] In the arrangement of
[0064] In a preferred arrangement, the wedge blocks 110a, 110b are fabricated from a metal such as ductile iron. Alternatively, a cementitious or hardened polycarbonate material may be used. In the event technology so develops, wedge blocks may be formed through an additive manufacturing process.
[0065] The wedge blocks 110a, 110b each offer aligned through-openings 115. For each wedge block 110, a through-opening 115 is provided in the inside (or front) wall 114 and in the outside (or back) wall 116. Preferably, each wedge block 110a, 110b offers two pairs of aligned through-openings 115. This is true whether the base is hollow or is otherwise solid.
[0066] In one aspect, each through-opening 115 includes threads (shown at 115 in
[0067] A person of ordinary skill in the art will understand that to arrange for this push-pull relationship between the wedge blocks 110a, 110b, the threads 132 may need to have opposite thread-hands from each other.
[0068] In one embodiment, the bars 130 simply slide through the through-openings 115. To accommodate the push-pull arrangement, nuts 135 are provided along the bars 130. The nuts 135 are rotated away from the opposing inside 114 and outside 116 walls of the respective wedge blocks 110a, 110b. Each of the one or more threaded bars 130 is then rotated in either a clockwise direction or in a counter-clockwise direction, simultaneously. This will serve to either draw the wedge blocks 110a, 110b together (i.e., inwardly) or push the wedge blocks 110a, 110b apart (i.e., outwardly).
[0069] To pull the wedge blocks 110a, 110b together, the operator may turn the inside nuts 135I to provide space relative to the inside walls 114. The outside nuts 135O are then rotated simultaneously while the bars 130 are held in place. This moves the wedge blocks 110a, 110b inwardly. The inside nuts 135I may then be tightened back down onto the inside walls 114 and the wedge blocks 110a, 110b are held in place.
[0070] To push the wedge blocks 110a, 110b apart, the operator may turn the outside nuts 135O to provide space relative to the outside walls 116. The inside nuts 135I are then rotated while the bars 130 are held in place, to move the wedge blocks 110a, 110b outwardly. The outside nuts 135O may then be tightened back down onto the outside walls 116.
[0071] It is understood that patent drawings do not need to be presented at spec level and the threads 132L, 132R may be considered schematically (i.e., showing helices in the same direction or in opposite directions) and yet function to provide the push-pull relationship as set forth in the claims. For example, the helices may be presented in the same direction (as set forth in
[0072] The pipe support system 100 also preferably includes a cap 120. Each cap 120 is designed to snap-fit onto the angled top surface 118 (as discussed in further detail below). Each cap 120 is fabricated from a polycarbonate material, polyurethane or a synthetic thermoplastic linear polyamide (or nylon). Nylon is preferred as it offers a combination of high strength and relatively low friction. One suitable example of a nylon material is Nylatron GSM, available from Quadrant EPP USA Inc. of Reading, Pa. Nylatron GSM contains finely divided particles of molybdenum disulphide (MoS.sub.2) to enhance load bearing capabilities while maintaining the impact resistance inherent to nylon. Other Nylatron products may also be considered. However, it is preferred that whatever plastic or other material is used, it should preferably have UV stabilizers and be non-conductive.
[0073] It is noted that the caps 120 each include a plurality of channels 125. The channels 125 are configured to permit water to flow under a pipe and then off of the wedge blocks 110. This prevents corrosion of the pipe due to water build-up on the wedge blocks 110, such as may be caused by rain. For this reason, the caps 120 may be referred to as corrugated caps.
[0074] The channels 125 of the caps 120 may be of any design so long as they facilitate the gravitational wicking away of water. Preferably, the channels 125 are oriented transverse to a longitudinal axis of the angled cap 120.
[0075] It is observed that the caps 120 may snap-fit onto the respective wedge blocks 110a, 110b without the top surfaces 118 being present. In other words, there is no requirement that the wedge blocks 110a, 110b have a top surface 118 in addition to the caps 120. However, the top surfaces 118 do help provide stability to the both the caps 120 and the underlying wedge blocks 110a, 110b while supporting a pipe 200.
[0076] As noted, the pipe support system 100 additionally includes at least one threaded bar 130. In the arrangement of
[0077]
[0079] The threaded ends 132 are configured to receive a nut 135. Each nut 135 may be tightened down against the outside wall 116 of the wedge blocks 110a, 110b in order to adjust the spacing. In addition, a second nut 135 may be placed along each threaded bar 130 to abut an inside wall 114. Such a second nut 135 is depicted in the end view of
[0080] The operator may rotate the threaded bars 130 (relative to the nuts 135 or, alternatively, relative to threads 115 in the through-openings 115) in a first direction in order to draw the wedge blocks 110a, 110b inwardly, or rotate the threaded bars 130 the opposite direction to move the wedge blocks 110a, 110b outwardly. It is understood here that the term rotate includes relative rotation such as rotating the nuts 135 to provide part of the spacing adjustments. Ideally, the rotation of the two bars 130 occurs simultaneously.
[0081] It is also understood that the pipe support system 100 will operate well with one threaded bar 130 or with three threaded bars 130, as opposed to the two bars 130 shown. Of course, if only one threaded bar 130 is used, the bar 130 will ideally be positioned central to the respective wedge blocks 110a, 110b as opposed to being positioned closer to ends 112. Thus, the phrase one or more threaded bars in the claims will be well understood.
[0082]
[0083] It is understood that the present inventions are not limited by the type of pipe employed. The pipe 200 may be part of a pipeline used to convey fluids such as produced water, crude oil, brine, potable water, sewage or hydrocarbon gases. Produced hydrocarbons may be transported from the field into a gathering facility, a treatment facility or a refinery using the pipe 200. Processed fluids may be transported from a treatment facility or a refinery using the pipe 200.
[0084] In any instance, the pipe support system 100 may also include an optional base plate 140. In the arrangement of
[0085] The plate 140 includes opposing edges 142. The edges 142 are linear and are parallel to one another. The wedge blocks 110a, 110b and supported pipe 200 are configured to rest on the base plate 140. Of interest, a recessed area 117 is preserved in the middle of the wedge blocks 110. The recessed areas 117 allow the wedge blocks 110a, 110b to each straddle the base plate 140. This stabilizes the wedge blocks 110a, 110b, preventing them from shifting, that is, moving forward or backward, during thermal expansion that takes place within the pipe 200. The result is that the corrugated caps 120 end up serving as wear plates.
[0086] To enable the wedge blocks 110a, 110b to straddle the base plate 140, the end walls 112 are configured to have feet 111. The feet 111 frictionally reside along the respective edges 142 of the base plate 140. The feet 111 secure the wedge blocks 110a, 110b as they are moved inwardly or outwardly. Such movement may be applied, for example, in connection with the servicing of the wedge blocks 110a, 110b, including the inspection and replacement of worn caps 120.
[0087]
[0088] The wedge block 310A of
[0089]
[0090]
[0091]
[0092] It is noted that over time the corrugated cap 120 and its channels 125 will experience wear. This is due to a combination of weathering and friction. The friction comes from movement of the pipe 200 due to thermal expansion and contraction. In the event a corrugated cap 120 needs to be replaced, it can simply be snapped or pried off of the walls 114, 116. If necessary, the cap 120 can just be sacrificed through use of a hammer, and readily replaced at low cost.
[0093]
[0094]
[0095] As an additional and optional feature of the pipe support system 100, a spacer may be provided.
[0096] The spacer 700 is dimensioned to reside along a threaded bar 130 intermediate the two wedge blocks 110a, 110b. In this respect, the cylindrical opening (or inner diameter) 705 that extends through the spacer 700 is dimensioned to receive the threaded bar 130. The spacer 700 allows for the user to precisely set the distance between the wedge blocks 110a-110b, thereby making the support structure 100 appropriately sized for different sized pipes.
[0097] In one aspect, the angle of the corrugated caps 120 is between 20 and 40 relative to a surface on which the first wedge block and the second wedge block sit. More preferably, the angle of the caps is at 30. A mathematical table may be provided to the user, correlating the size of the pipe 200 to the desired spacer 700 length in order to optimize the position of the pipe 200 on the corrugated caps 120, correlated to the angle of the caps 120.
[0098] Ideally, the point at which the pipe 200 touches the corrugated caps 120 is a tangent line, meaning that the angle of the tangent line and the angle of the corrugated caps 120 is within a few degrees of each other. The mathematical table will inform the user of the needed spacer length to achieve the tangent line. Of course, if the corrugated caps 120 are designed to have a different angle, then the spacer lengths on the mathematical table will need to be tweaked.
[0099]
[0100] An additional line B is provided. Line B is a vertical line which bisects angle . Further, a horizontal line 700L is provided, connecting tangent lines 820 and also bisected by line B. Mathematically, line 700L depicts a length of spacer 700. Thus, for a pipe 200 having radius R, the operator would select a spacer 700 having length 700L.
[0101]
[0102] Using the pipe support system 100 described above, a method of supporting a section of pipe is also provided herein. In one embodiment, the method first comprises providing a pipe support system. The pipe support system may be in accordance with the pipe support system 100 described above in its various embodiments. For example, the pipe support system may include: [0103] a first wedge block and a second wedge block, wherein each of the first and second wedge blocks comprises a base and an angled top surface, with the angled top surfaces facing one another [0104] at least one through-opening through each of the first and second wedge blocks, wherein the respective through-openings are aligned, and [0105] at least one threaded bar configured to extend through aligned through-openings in each of the first wedge block and the second wedge block.
[0106] The method also includes determining a spacing between the first wedge block and the second wedge block in order to support a joint or section of pipe having an outer diameter. The method then includes rotating each of the threaded bars in order to provide for the determined spacing. It is understood that for purposes of the claims, the term rotating each of the threaded bars includes relative rotation, such as rotating a nut secured to a threaded bar in order to tighten down the wedge blocks against the spacer bar.
[0107] In a preferred arrangement, each of the threaded bars may be rotated in a first direction to draw the first and second wedge blocks inward towards each other. Reciprocally, each of the threaded bars may be rotated in a second opposite direction to allow the first and second wedge blocks to be moved outward from each other.
[0108] The method further comprises placing the joint or section of pipe onto the pipe support system. In this way the pipe is supported above a ground surface.
[0109] In one embodiment, the method also includes securing a separate bearing plate onto each of the wedge blocks. Each of the bearing plates is a frangible cap, such as nylon, residing on the angled top surface of the first and second wedge blocks, respectively. Each of the caps comprises corrugations or channels dimensioned to gravitationally wick away water to prevent water from building up along the outer diameter of the pipe.
[0110] Each of the corrugated caps comprises: [0111] a first side configured to land on a top of an outside wall of a base of a wedge block; [0112] a shoulder along the first side configured to wrap over the top of the outside wall of the wedge block; [0113] a second side configured to land on a top of an inside wall of the base of the wedge block; and [0114] a shoulder along the second side configured to wrap over the top of the inside wall of the wedge block.
[0115] An outer surface of the inside wall comprises a notch. At the same time, the shoulder along the second side comprises a lip that is dimensioned to snap-lock into the notch. Securing a bearing plate comprises snapping the bearing plate onto the base that forms the respective wedge block.
[0116] The method may further comprise replacing each of the corrugated caps after a period of wear. Replacing may mean unsnapping the bearing plate off of the base before snap-locking a new bearing plate onto the base. Alternatively, replacing may mean breaking the bearing plate, such as through hammering before snap-locking a new bearing plate onto the base. Thus, the corrugated cap is a sacrificial element as a result of use.
[0117] Finally, a method of replacing a bearing plate for a pipe support structure is provided herein. In one aspect, the method first comprises providing a pipe support system. The pipe support system is structure in accordance with the pipe support system 100 described above in its various embodiments. This includes a first wedge block and a second wedge block, wherein each of the first and second wedge blocks comprises a base.
[0118] The method also includes installing a bearing plate onto each of the first and second wedge blocks. This is done through a snap-lock fit. Each of the bearing plates comprises corrugations dimensioned to gravitationally wick away water to prevent water from building up along the outer diameter of pipe. In addition, each of the bearing plates resides at an angle of between 20 and 40 over the respective wedge blocks, wherein the angles are inwardly-facing.
[0119] Additionally, the method comprises determining a spacing between the first wedge block and the second wedge block. This is done in order to support a joint or section of pipe having an outer diameter. The method then includes placing the joint or section of pipe onto the pipe support system, thereby supporting the pipe above a ground surface.
[0120] After a period of time the bearing plates will experience wear. The method then includes removing the bearing plates from the respective wedge blocks. Then, again using a snap-lock fit, the method includes installing a replacement bearing plate onto each of the first and second wedge blocks. Each of the replacement bearing plates also comprises corrugations dimensioned to gravitationally wick away water to prevent water from building up along the outer diameter of pipe. In addition, each of the replacement bearing plates also resides at an angle of between 20 and 40 over the respective wedge blocks.
[0121] The particular embodiments disclosed above are illustrative only, as the embodiments may be modified and practiced in different but equivalent manners apparent to those skilled in the art having the benefit of the teachings herein. It is therefore evident that the particular embodiments disclosed above may be altered or modified, and all such variations are considered within the scope and spirit of the application.
[0122] In the claims which follow, the word comprising is used in its inclusive sense and does not exclude other elements being present. The indefinite articles a and an before a claim feature do not exclude more than one of the feature being present. Each one of the individual features described here may be used in one or more embodiments and is not, by virtue only of being described here, to be construed as essential to all embodiments as defined by the claims.
