Abstract
A pair of pipe members are joined together in a flange connection assembly particularly suited for fiber-reinforced plastic components, the pipe members being formed to include an inner pipe jacked consisting essentially of a thermoplastic material and an outer pipe jacket consisting essentially of a fiber winding impregnated with a snythetic resin. A threaded section is formed in each of the outer pipe jackets at the end of each of the pipe members, a flange bushing is provided with a loose flange ring threadedly engaged on each of the threaded sections and a covering collar covering at least the end of each of the pipe members is inserted at the inner pipe jacket.
