Abstract

The heating and/or sanitation pipe comprises an inner pipe (12) made of a plastic material and a metal corrugated pipe (14) surrounding the inner pipe (12) at a radial distance {circle around (R)}). Further, the heating and/or sanitation pipe is provided with a compressible and/or expanded material (16) between the inner pipe (12) and the corrugated pipe (14) for fixing the inner pipe (12) inside the corrugated pipe (14). The compressible and/or expanded material (16) is adapted to be detached from the inner pipe for the purpose of exposing a connecting end of the inner pipe (12). Further, the heating and/or sanitation pipe comprises an insulation layer (18) surrounding the metal corrugated pipe (14) and an outer covering (20) around the insulation layer (18).
