Abstract

The pipe, with thermal insulation, has an inner pipe (5) as a corrugated metal pipe or a smooth bendable copper pie. The thermal insulation layer (6) is of a hard polyurethane foam, free of FCKW, foamed by carbon dioxide, argon, pentane or a partially halogenated hydrocarbon. The coaxial outer pipe (7) is of a thermoplastic adhesive bonded to the hard polyurethane foam layer.
