Abstract

The multi-pipe assembly to carry media of different temps., such as in a remote heating network, has one pipe (2) for the hotter medium and a further pipe (3) for the cooler medium, using metal pipes held equidistantly from each other over their whole length within an oval or pear-shaped insulating shrouding (4). They are rigidly bonded together through at least two mountings (5, 6) at their surfaces so that a length expansion through heat at the hot pipe (2) is directed across the axis between the mountings. The gap between the mountings is twice the sum of the lengths between the mountings and their adjacent pipe (2, 3) ends. The shrouding (4) is of high density polyethylene, in a force fit with the pipes through polyurethane foam. The pipes (2, 3) are of steel and/or copper.
