Flexible composite pipe for high-temperature fluids
A flexible composite pipe for transporting a high-temperature fluid is described, comprising: an inner pipe consisting of a pipe obtained by extruding one member selected from the group consisting of polyvinylidene fluoride copolymer resins, blends thereof with polyvinylene fluoride resins, and compositions based on the polyvinylene fluoride polymer resins, which have, when hot pressed into a sheet, and Izod impact strength of not less than 10 kg-cm/cm and an apparent Young's modulus intension of not more than 90 kg/mm/sup 2/; an inner reinforcing layer formed around the inner pipe and an outer reinforcing formed around the inner reinforcing layer, a grease being injected in the inner and outer reinforcing layers; a plastic film inserted between the inner and outer reinforcing layers, and a protective sheet layer coated around the outer reinforcing layer.
