PROBLEM TO BE SOLVED: To provide a thermoplastic polymer and polyolefin based flexible pipe used at a digging area of an oil or a gas. SOLUTION: The off-shore flexible pipe provided with a sealing layer has (1) an inner layer comprising at least one kind of thermoplastic polymer (A); (2) a co-extrusion bonding layer used if necessary; and (3) a polyolefin layer in this order. In another embodiment, the sealing layer has (1) the inner layer comprising at least one kind of thermoplastic polymer (A); (2) the co-extrusion bonding layer used if necessary; (3) the polyolefin layer; (4) the co-extrusion bonding layer used if necessary; and (5) an outer layer comprising at least one kind of thermoplastic polymer (B) in this order. The flexible pipe having this sealing layer is used for a transportation of fluid at the off-shore digging area of the oil and the gas. COPYRIGHT: (C)2004,JPO |
