ABSTRACT:
A method of establishing pipe systems for hot media, such as subterranean district heating pipe systems, comprising arranging a number of pipe lengths in continuity of each other with a certain spacing between the adjacent ends thereof, and interconnecting these ends by means of relatively short, axially easily compressible conductor elements such as tube bellows, whereafter the pipe lengths are axially expanded by sending a hot medium through the pipe system thus assembled, until the single pipe lengths, at a temperature below the expected maximum operational temperature of the system, have expanded sufficiently to cause the adjacent pipe length ends to abut against each other, whereafter these pipe length ends, by welding, bolting or otherwise, are joined rigidly to each other. Hereby the pipes may be anchored rigidly to their surroundings and be subjected to temperature variations without the lack of thermal movability of the pipes causing unpermissible stress in the pipes.
