Abstract

The district heating system comprises sets each of two coaxial pipes and a thermal insulating layer between, the two pipes being fixed together at one end, while at the other the inner one containing the heating medium moves freely in relation to the insulation and the outer one. The inner pipes are coupled together by sockets, smooth ends, and there are seals between them. The socket of each inner pipe has a flange protruding radially outwards, and against which the respective outer pipe bears. The outer pipe of the adjacent set also bears against the end face of this flange.
