| مستخلص: | A pipe and pipe support interface structure comprised of a fiberglass C-shaped bearing surface saddle structure having a high strength, low friction, non-corrosive bearing surface block comprised of UHMWPE or other suitable polymer materials is disclosed. The bearing surface saddle structure is adhesively bonded to the exterior surface of a pipe following appropriate pipe surface preparation at locations where the pipe contacts a pipe support surface. The bearing surface block of the bearing surface structure provides an interface between the pipe and pipe support surface in order to protect the pipe from wear caused by bearing on a pipe support. The C-shaped bearing surface saddle structure described will increase the load bearing area of the pipe at the pipe support and serve to prevent wear on both the pipe and the pipe support. The C-shaped bearing surface saddle structure and method may be employed in the field as part of a maintenance and repair program. |

| Claim: | 1. A pipe and a pipe support in combination, comprising: (a) the pipe; (b) the pipe support, said pipe generating a load; (c) a C-shaped saddle configured to support said pipe; (d) a rectangular polymer bearing surface block supporting said C-shaped saddle; and (e) an adhesive layer bonding said C-shaped saddle to said bearing surface block, said bearing surface block positioned between said C-shaped saddle and said pipe support, thereby spreading said load generated by said pipe to said bearing surface block on said pipe support thereby prodding an increased surface area for distributing said pipe load on said pipe support. |
| Claim: | 2. The pipe and pipe support interface structure as recited in claim 1 wherein said polymer bearing surface block is comprised of ultra-high molecular weight polyethylene. |
| Claim: | 3. The pipe and pipe support interface structure as recited in claim 1 wherein said polymer bearing surface block is comprised of nylon. |
| Claim: | 4. The pipe and pipe support interface structure as recited in claim 3 wherein said polymer bearing surface block includes molybdenum disulfide lubricant powder. |
| Claim: | 5. The pipe and pipe support interface structure as recited in claim 2 wherein said adhesive layer is a structural plastic adhesive. |
| Claim: | 6. The pipe and pipe support interface structure as recited in claim 5 wherein said C-shaped saddle is fiberglass. |
| Claim: | 7. The pipe and pipe support interface structure as recited in claim 4 wherein said C-shaped saddle is fiberglass. |
| Claim: | 8. The pipe and pipe support interface structure as recited in claim 7 wherein said adhesive layer is a structural adhesive. |
| Claim: | 9. A pipe support interface structure comprising: (a) a C-shaped saddle configured to support a pipe, said pipe generating a pipe load; (b) a polymer bearing surface block supporting said saddle; (c) a first adhesive layer and a second adhesive layer, said first adhesive layer adhesively bonding said bearing surface block to said C-shaped saddle, said second adhesive layer adhesively bonding said C-shaped saddle to said pipe and wherein said bearing surface block is positioned between said C-shaped saddle and a pipe support surface; and (d) whereby said bearing surface block provides an increased load bearing surface area between said pipe and said pipe support surface for distributing said pipe load to said pipe support surface. |
| Claim: | 10. The pipe support interface structure recited in claim 9 wherein said polymer bearing surface block is a rectangular block comprised of ultra-high molecular weight polyethylene and said C-shaped saddle is fiberglass. |
| Claim: | 11. The pipe support interface structure as recited in claim 9 wherein said polymer beating surface block is comprised of nylon. |
| Claim: | 12. The pipe support interface structure as recited in claim 10 wherein said polymer bearing surface block includes molybdenum disulfide lubricant powder. |
| Claim: | 13. The pipe support interface structure as recited in claim 10 wherein said first adhesive layer is a structural plastic adhesive. |
| Claim: | 14. The pipe support interface structure as recited in claim 13 wherein said second adhesive layer is double-side adhesive tape. |
| Claim: | 15. A method for providing a pipe and pipe support interface structure between the pipe and a pipe support comprising the steps of: (a) providing the pipe; (b) providing a pipe support surface, said pipe creating a load on said pipe support surface; (c) removing and cleaning any corrosion, dirt or foreign substance from said pipe and said pipe support surface; (d) providing a C-shaped saddle, said C-shaped saddle having a polymer bearing surface block adhesively bonded to said C-shaped saddle, said block providing an increased bearing surface between said C-shaped saddle and said pipe support surface; (e) providing a layer of adhesive between said C-shaped saddle and said pipe surface; (f) adhesively bonding said C-shaped saddle to said pipe surface; and (i) positioning said C-shaped saddle between said pipe surface and said pipe support surface whereby said polymer bearing surface block is in contact with said pipe support surface, thereby distributing said load generated by said pipe across said pipe support surface. |
| Claim: | 16. The method as recited in claim 15 wherein said step of providing a layer of adhesive between said C-shaped saddle and said pipe surface includes providing double sided adhesive tape. |
| Claim: | 17. The method as recited in claim 16 wherein said step of providing a C-shaped saddle includes providing a C-shaped saddle made of fiberglass and wherein said polymer bearing surface block is a rectangular block adhesively bonded to said fiberglass C-shaped saddle with structural plastic adhesive. |
| Claim: | 18. The method as recited in claim 17 , wherein said step of providing a C-shaped saddle attached to said polymer bearing surface block includes constructing said polymer bearing surface block from ultra high molecular weight polyethylene. |
| Claim: | 19. The method as recited in claim 17 , wherein said step of providing a C-shaped saddle attached to said polymer bearing surface block includes constructing said polymer bearing surface block from nylon. |
| Claim: | 20. The method as recited in claim 19 , wherein said step of providing a C-shaped saddle attached to said polymer bearing surface block includes constructing said polymer bearing surface block from molybdenum disulfide lubricant powder. |
