Abstract

It is previously known that district heating pipes, the inner conduit 4 of which consists of annealed copper, can be laid without the use of axial compensating means, because of the special relaxation properties of this material. In the invention, it has been found that a considerably cheaper material, aluminium, has corresponding properties to the degree necessary for this application, and it is necessary only to enclose the pipe 6 in an inner and an outer plastic coating 8, 10. When metal pipe joint parts 22, 24 are used, care should be taken that there is no galvanic contact with the aluminium. The resultant district heating pipe 2 is well-suited to being transported in the rolled state 16 and to being laid in long lengths by being shot through the ground between wet wells 18,20. <IMAGE>
