Abstract
Proposed is a pipe (1), more particularly a district heating pipe, comprising a medium-carrying pipe (2) and lagging (3), more particularly made of polyurethane foam, which surrounds the medium-carrying pipe (2), wherein the medium-carrying pipe (2) and the lagging (3) are embedded in a thermoplastic outer pipe (4). To improve the heat insulation capacity it is proposed that at the end of the pipe the lagging (2) be provided with a barrier polymer (5) which is covalently bonded to the lagging (2).
