Pipe support

Abstract

A pipe support structure comprised of a series of blocks mounted on a base to create opposing ridges arrayed on opposite sides of a central drainage channel. The ridges have a rounded curved outer surface and create intervening valleys that are sloped to direct fluid flow into the central drainage channel. The ridges are arranged and oriented so that the curved outer surface of the ridges support the pipe on its peripheral underside above with the drainage channel and create a space between the bottom of the pipe and the base. The blocks may be angled to further facilitate desired drainage into the drainage channel.

DESCRIPTION OF EMBODIMENT

(10) FIGS. 1-3 show the pipe support structure (10) of applicant's invention. The pipe support structure (10) is comprised of a longitudinally extending base (14) having a longitudinal centerline (CL) on which is mounted a plurality of support blocks (15). The support blocks (15) are arranged with upper arching curved surfaces to create a series of opposing ridges (16) arrayed on opposite sides of the longitudinal centerline (CL) of the base (14). The series of ridges (14) are sized, oriented, and spaced apart to create intervening valleys (17) between each ridge (16).

(11) As best seen in FIG. 1, blocks (15) are arranged to create interconnected ridges (16) and intervening valleys (17 forming a surface profile (13) in the shape of a wave such as a sinusoidal wave. A waved profile (13) will provide a smooth transition between each ridge (16) and valley (17) to promote the flow of fluid into channel (18). As best seen in FIG. 2, the pipe support structure (10) is shown mounted on a support surface (12) of a pipe system. The blocks (15) of pipe support structure (10) are arranged and oriented on base (14) so that the ridges (16) abut and support a pipe (P) longitudinally on its peripheral underside and not from directly underneath pipe (P).

(12) The wave shaped profile (13) of the ridges (16) and valleys (17) of blocks (15) combined with the tapered downward slope of base (14) will enhance the flow of fluid into channel (18) and away from pipe (P) and provide a means for removing fluid away from the surface of pipe (P). This will eliminate the need for frequent inspection and rehabilitation of the pipe support structure and ultimately reduce the cost of inspection, maintenance, and repair. As shown in FIG. 2, the base (14) is sloped at a desired slope angle () so that fluid such as rainwater is directed from the valleys (17) to flow to the channel (18) for drainage. A base (14) having slope angle () in the range of 5 to 20 degrees is thought to be sufficient for diverting fluid to the channel (18). An angle () outside that range, i.e., less than 5 degrees or greater than 20 degrees, may be sufficient to achieve desired drainage depending upon the environmental conditions where the pipe support structure (10) will be utilized.

(13) The curved surfaces and ridges (16) of the blocks (15) direct fluid down the curved surface into intervening valleys (17) and away from the pipe (P) preventing the accumulation of fluid in contact with pipe (P). The base (14) is tapered downward toward centerline (CL) to create a draining flow of fluid (indicated by arrows) from the valleys (17) into a drainage channel (18) on base (14). The tapered base and drainage channel create fluid flow paths to divert and drain fluid away from the surface of the supported pipe (P).

(14) The base (14) may be further provided with bolt holes (22) to facilitate securing of the pipe support structure (10) to the main support surface (12) of a pipe system with anchor bolts as a means (23) for affixing the pipe support structure (10) to the main support structures (12). The affixing means (23) may be any pin, screw, bolt, rivet, or other fastening means conventional in the art. Affixing means (23) may also be an adhesive such as glue, epoxy, or grout that provides a bond to affix the pipe support structure (10) to the main support structures (12).

(15) As shown in FIGS. 1 and 2, the ridges (16) raise the pipe above base (14) and channel (18) to prevent the pipe (P) from resting in a pool of fluid. This will allow drainage and prevent moisture from being collected and trapped beneath pipe (P) which would otherwise cause wear and corrosion of pipe (P). Fluid runs onto and down the sides of pipe (P), over and down the curved ridge surfaces of the support block (15) into valleys (17) between the ridges (16), and down the sloped base (14) into channel (18) at the bottom of the base (14), wherein it runs to the end of channel (18) and falls off onto the support surface (12) or onto grade.

(16) FIG. 3 is a top view of the pipe support structure (10) showing orientation of the blocks (15) and support ridges (16) along the length of the base (14). The ridges (16) may be arrange at any desired angle () with respect to the horizontal centerline (CL) of the base (14) in order to create a suitable valley (17) with sufficient space for drainage and provide adequate support on the peripheral underside of the pipe (P). An angle () in the range of 25 to 35 such as 30 is thought to be sufficient though angles of lesser or greater degrees may also be implemented to achieve desired drainage.

(17) The base (14) may be provided with predetermined break points (11) to allow the pipe support structure (10) to be adjusted or altered in the field to accommodate a particular pipe support situation. The predetermined break points (11) may be a scored or notched area on the surface of the base to allow the pipe support structure (10) to be readily broken down or cut into segments if the need for a shorter pipe support structure is required.

(18) FIGS. 4-6 show pipe support structure (20) as an alternate embodiment of pipe support structure (10). Pipe support structure (20) is comprised of a base (14) upon which is mounted a plurality of substantially rectangular shaped support blocks (25) having an arched or rounded top and side surface (29). The support block (25) with arching curved surfaces (29) are arranged to create a series of opposing ridges (26) arrayed on opposite sides of the centerline (CL) of the base (14). The series of ridges (26) are sized, oriented, and spaced apart to flat intervening valleys (27) between each ridge (26). Blocks (25) having such arched or curved surfaces (29) will cause fluid to be directed down the curved surface (29) into intervening valleys (27) and away from the pipe (P), thus preventing the accumulation of fluid in contact with pipe (P). The base (14) is tapered downward towards centerline (CL) to create a draining flow of fluid (indicated by arrows) from the valleys (27) into a drainage channel (28) on base (14) to create a path to divert and drain fluid away from the surface of the pipe (P).

(19) The spaced orientation of rounded blocks (25) create ridges (26) and flat intervening valleys (27) upon base (14). The combination of the rounded surfaces of ridges (26) with the flat valleys (27) promotes fluid and contaminants to travel down the tapered surface of base (14) a and into the intersecting surfaces creating drainage channel (28).

(20) FIG. 6, similar to that of FIG. 2, shows the pipe support structure (20) mounted on a support surface (12) of a pipe system. The blocks (25) are arranged and oriented longitudinally on base (14) so that the curved ridges (26) support a longitudinally oriented pipe (P) on its peripheral underside and not from directly underneath pipe (P). The base (14) is sloped at a desired slope angle () so that fluid from the valleys (27) is directed to flow to the channel (28) for drainage. A slope angle () in the range of 5 to 20 degrees is envisioned to be sufficient though angles of lesser or greater degrees may also be implemented to achieve desired drainage. The base (14) may be further provided with bolt holes (22) to facilitate securing of the pipe support structure (20) to the main support surface (12) of a pipe system through use of affixing means (23). Affixing means (23) includes pins, screws, bolts, rivets, and adhesives and bonding agents such as glue, epoxy, or grout.

(21) The curved surface (29) of ridges (26) raise the pipe (P) above base (14) and channel (28) to prevent the pipe (P) from resting in a pool of fluid. This allows drainage and prevention of moisture from trapping beneath pipe (P) which would otherwise cause wear and corrosion of pipe (P). Fluid runs onto and down the sides of pipe (P), over and down the rounded curved surfaces of the support blocks (25) into valleys (27) between the ridges (26), and down the sloped base (14) into channel (28) at the bottom of the base (14), and then to the end of channel (28) to fall onto the support surface (12).

(22) FIG. 5 is a top view of pipe support structure (20) showing orientation of the support ridges (26). The ridges (26) may be arrange at any desired angle () with respect to the horizontal centerline (CL) of the base (14) in order to create a suitable valley (27) with sufficient space for drainage and provide adequate support on the peripheral underside of the pipe (P). An angle () in the range of 25 to 35 such as 30 is thought to be sufficient though angles of lesser or greater degrees may also be implemented to achieve desired drainage.

(23) FIGS. 7-9 show pipe support structure (30) as an alternate embodiment of pipe support structure (10). Pipe support structure (30) is comprised of a base (14) on which is mounted a plurality of rounded support blocks (35) having a substantially egg or ovate shape. The support blocks (35) are arranged with arching curved surfaces (39) to create a series of opposing ridges (36) arrayed on opposite sides of the centerline (CL) of the base (14). The series of ridges (36) are sized, oriented, and spaced apart to flat intervening valleys (37) between each ridge (36). Blocks (35) having such curved surfaces causes fluid to be directed down the curved surface into intervening valleys (37) and away from the pipe (P), thus preventing the accumulation of fluid in contact with pipe (P). The base (14) is tapered downward towards centerline (CL) to create a draining flow of fluid (indicated by arrows) from the valleys (37) into a drainage channel (38) on base (14) to create a path to divert and drain fluid away from the surface of the pipe (P).

(24) As shown in FIG. 7, the spaced orientation of blocks (35) comprising ridges (36) creates flat intervening valleys (37) upon base (14). The combination of the rounded surfaces of ridges (36) with the flat valleys (37) promotes fluid and contaminants to travel down the tapered surface of base (14) and into the intersecting surfaces creating drainage channel (38).

(25) FIG. 9 shows the pipe support structure (30) mounted on a support surface (12) of a pipe system in a manner to that shown for pipe support structure (10) and pipe support structure (20). The blocks (35) are arranged and oriented on base (14) so that the curved surfaces (39) of ridges (36) support pipe (P) on its peripheral underside and not from directly underneath pipe (P). The base (14) is sloped at a desired slope () so that fluid from the valleys (37) is directed to flow to the channel (38) for drainage. A slope angle () in the range of 5 to 20 degrees is envisioned to be sufficient though angles of lesser or greater degrees may also be implemented to achieve desired drainage. The base (14) may be further provided with bolt holes (22) to facilitate securing of the pipe support structure (20) to the main support surface (12) of a pipe system through use of affixing means (23). Affixing means (23) includes pins, screws, bolts, rivets, and adhesives and bonding agents such as glue, epoxy, or grout.

(26) The ridges (36) raise the pipe (P) above base (14) and channel (38) to prevent the pipe (P) from resting in a pool of fluid. This allows drainage and prevention of moisture from trapping beneath pipe (P) which would otherwise cause wear and corrosion of pipe (P). Fluid runs onto and down the sides of pipe (P), over and down the rounded surfaces (39) of the support blocks (35) into valleys (37) between the rides (36), and down the sloped base (14) into channel (38) at the bottom of the base (14), and off the end of channel (38) onto the support member (12) or grade.

(27) FIG. 8 is a top view of the pipe support structure (30) showing orientation of the support ridges (36). The ridges (36) may be arrange at any desired angle () with respect to the horizontal centerline (CL) of the base (14) in order to create a suitable valley (37) with sufficient space for drainage and provide adequate support on the peripheral underside of the pipe (P). An angle () in the range of 25 to 35 such as 30 is thought to be sufficient though angles of lesser or greater degrees may also be implemented to achieve desired drainage.

(28) Pipe support structures (10), (20), and (30) may be constructed from any suitable material including non-corrosive metals or metal alloys, such as but limited to those of aluminum, steel, and titanium, or these structures may be constructed of plastic or polymer materials. Preferably the pipe support structures (10), (20), and (30) will be molded from non corrosive thermoplastic polymer materials and composites. Thermoplastic polymer materials and composites suitable for molding the pipe support structure include polyethylene (PE) and polyethylene composites including high-density polyethylene (HDPE), ultra-high molecular weight PE (UHMWPE), and medium-density PE (MDPE), or a combination of such materials, and including those materials with reinforcing fibers.

(29) The pipe support structures (10), (20), and (30) may also be cast or machined from metal or metal alloys such as stainless steel, titanium, titanium alloys, aluminum or aluminum alloys. The support structures (10), (20), and (30) may be made metal or metal alloys that are inherently non-corrosive. Pipe structures (10), (20), and (30) constructed of metal or metal alloys may be provided with a non-corrosive coating such as a polymer coating to further impede corrosion of the support during use. In harsh environments non-corrosive metals or metal alloys may be more suitable due to their advantages of structural strength and non-corrosive characteristics.

(30) When molded or cast pipe support structures (10), (20), and (30) may be formed in convenient lengths or strips and cut in the field in segments of a desired length to match a particular support situation. This will allow a user to customize a pipe support in the field as desired. A single segment of a pipe support structure (10), (20), or (30) may be fitted under the pipe (P) or multiple segments of a pipe support structure (10), (20), or (30) may be used depending upon the pipe (P) to be supported and the characteristics of the underlying support (12) where the pipe support structures (10), (20), or (30) are used.

(31) The installation method includes locating a pipe (P) positioned upon a support surface (12) and providing a pipe support structure (10), (20), or (30). The pipe (P) is then lifted off the support and a pipe support structure (10), (20), or (30) is mounted on the support surface (12). The pipe (P) is then placed upon the so that the curved surfaces of ridges (16, 26, or 36) support pipe (P) on its peripheral underside and not from directly underneath pipe (P).

(32) When replacing an existing pipe support with a pipe support structure (10), (20), or (30), the pipe (P) is lifted from the existing pipe support, the existing pipe structure is removed from the support surface (12) and replaced with a desired pipe support structure (10, 20, or 30). After removing an existing pipe support, it may be necessary to clean the pipe (P), the pipe support surface (12) of any adherent fluid, rust, or deleterious materials which would enhance corrosion or affect the drainage of fluid from the replacement pipe support structure (10, 20, or 30). Further, during replacement of an existing pipe support, it may be necessary to replace any damaged corrosion protection coatings that may be placed around the pipe (P). No welding, adhesives, or other costly installation techniques are typically required.

(33) Though this specification is directed toward using the pipe support structures (10, 20, or 30) to support a length of pipe, the term pipe, it is not intended to restrict the use of a pipe support structure (10, 20, or 30) to a single purpose. The pipe support structures (10, 20, or 30) may be used to support and direct fluid flow away from a variety of structures requiring support and protection including, tubular vessels and not just lengths or segments of pipe. In particular, it is envisioned that the pipe support structures (10, 20, or 30) may be used to support instrumentation tubing, conduit for electrical power line, conduit for process instrumentation and sensing, pressure vessels, tanks, and the like such as may be used in power generation, chemical and petrochemical facilities, transportation facilities, oil and gas platforms, agricultural facilities, wastewater treatment facilities, and manufacturing facilities without limitation.

(34) It is thought that the pipe support structures (10, 20, or 30) and the methods of the present invention and their attendant advantages will be understood from the foregoing description. It is also thought that one may make various changes in the form, construction and arrangement of the parts of the pipe support structures (10, 20, or 30) and methods described without sacrificing their material advantages or departing from the spirit and scope of the invention.
