A liner includes a rubber liner portion, and a polyurethane liner portion disposed on a surface of the rubber liner portion. The rubber polyurethane liner can be applied to cover surfaces of process support elements used to transport or handle process material such as tar sand slurry. The rubber pol

대표청구항 ▼

1. An apparatus for transporting a tar sands slurry, the apparatus comprising: at least one pipe element in a pipeline, the pipe element comprising an inner surface defining an internal passageway therein;a rubber layer disposed on the inner surface of the pipe element; andmeans for covering the rubber layer to protect the rubber layer from the tar sands slurry while the tar sands slurry is being transmitted inside the pipe element. 2. The apparatus of claim 1, comprising means for covering the rubber layer to protect the rubber layer from the tar sands slurry comprising hydrocarbons and particulate material. 3. The apparatus of claim 2, wherein the rubber layer is configured to provide cushioning for impacts of the particulate material of the tar sands slurry. 4. The apparatus of claim 1, comprising means for covering the rubber layer to protect the rubber layer from the tar sands slurry comprising hot water. 5. The apparatus of claim 1, wherein the means for covering the rubber layer is thicker than the rubber layer. 6. A pipe for transporting a tar sands slurry, the pipe comprising: a pipe element, the pipe element comprising an inner surface defining an internal passageway therein;a rubber layer disposed on the inner surface of the pipe element; anda heat-cured polyurethane layer covering the rubber layer such that the heat-cured polyurethane layer prevents contact between the rubber layer and the tar sands slurry, andwherein the heat-cured polyurethane layer is thicker than the rubber layer. 7. The pipe of claim 6, wherein the rubber layer acts as a permeability barrier to prevent blistering or disbondment of the heat-cured polyurethane layer due to vapor permeability or cold wall effect. 8. The pipe of claim 6, wherein the rubber layer provides cushioning for impacts of particulate matter of the tar sands slurry. 9. The pipe of claim 6, wherein the heat-cured polyurethane layer is cured at a temperature in the range of about 140 to 170 degrees Fahrenheit. 10. A method of transporting a tar sands slurry, the method comprising: providing at least one pipe element in a pipeline, the pipe comprising: an inner surface defining an internal passageway therein;a rubber layer disposed on the inner surface of the pipe element; anda heat-cured polyurethane layer covering the rubber layer; andmoving the tar sands slurry through the pipe element wherein the tar sands slurry contacts the heat-cured polyurethane layer and the heat-cured polyurethane layer prevents contact between the rubber layer and the tar sands slurry and thereby extends the useful life of the pipe element. 11. The method of claim 10, wherein the heat-cured polyurethane layer is thicker than the rubber layer. 12. An apparatus for transporting a tar sands slurry comprising hydrocarbons and particulate material, the apparatus comprising: at least one pipe element in a pipeline, the pipe element comprising an inner surface defining an internal passageway therein;first means for covering an inner surface of the pipe element and providing cushioning for impacts due to the particulate material being transported in the pipe element; andsecond means for protecting the first means from the hydrocarbons and the particulate material being transported inside the pipe element. 13. The apparatus of claim 12, wherein the first means comprises a rubber layer. 14. The apparatus of claim 13, wherein the second means is configured for resisting hot water. 15. The apparatus of claim 13, wherein the second means comprises a heat-cured polyurethane layer. 16. The apparatus of claim 15, wherein the heat-cured polyurethane layer is cured at a temperature in the range of about 140 to 170 degrees Fahrenheit. 17. The apparatus of claim 12, further comprising adhesive means for adhering the first means to the pipe element. 18. The apparatus of claim 17, further comprising primer means for adhering the adhesive means to the inner surface of the pipe element. 19. The apparatus of claim 12, wherein the second means is thicker than the first means.
