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 ).
