Abstract

In the laying of straight stretches of heat insulated district heating pipes it is known that the usual problems with respect to thermally conditioned expansions and contractions can be entirely avoided, if the pipes are of annealed copper with its associated special and relevant relaxation properties. With the invention it has been found that much cheaper pipes (2) of aluminium have similar properties, whereby these pipes are applicable when only a galvanic insulation (8, 10, 36) is provided between the pipes and the surroundings for counteracting galvanic corrosion. It is disclosed how this is achievable with particularly developed pipe joints, and it is emphasized that the pipes will be well suited to be mounted in the ground without the digging of trenches, viz. in being shot through the ground between wells (18, 20) spaced e.g. 50 m or more from each other.
