Chemical and gas-resistant, high-pressure, large-bore bonded flexible rubber pipe and method for producing the same |
| 摘要 |
A high-pressure, large-bore bonded flexible rubber pipe resistant to aggressive chemicals and gases, particularly for conveying gas or oil, the flexible pipe having a liner made of poly(vinylidene-fluoride) homopolymer or copolymer wherein a hydrogenated nitrile rubber-based, peroxide-vulcanized rubber compound 2 is bonded to the poly(vinylidene-fluoride) liner, which has a Mooney 05, 150° C. scorch time of at least 10 minutes. Further, a method for manufacturing such hoses, the method including vulcanization performed at a temperature of at least 160° C. |

1. A high-pressure, large-bore bonded flexible rubber pipe resistant to aggressive chemicals and gases, particularly for conveying gas or crude oil, the flexible pipe comprising a liner made of poly(vinylidene-fluoride) homopolymer or copolymer, with at least 80 mole % of the monomeric units being vinylidene-fluoride and a hydrogenated nitrile rubber-based rubber compound vulcanized with peroxide, which has a Mooney 05, 150° C. scorch time of at least 10 minutes, bonded to the poly(vinylidene-fluoride) liner. |
