Title: Pipe line arrangement for district heating - pipes are laid in sinusoidal lines to reduce possibility of fracture
Inventor: LUNDBOHM LENNART
IPC: F16L1/028
Filed: 1973-10-19
Abstract: District heating pipe lines are laid in the form of a sinusoidal wave in a trench in the ground with the plane of the wave horizontal. The wave has crests or troughs of between 8 and 30 metres length and the pipe should nowhere subtend an angle greater than 15 deg. to the mean direction of the pipe and preferably this angle is between 3 deg. and 6 deg. In this way expansion (especially of the hot water pipe) is accommodated without the need for sliding supports and contact corrosion between the hot and colt water pipes can be avoided by laying the pipes one above the other in the trench. Pipe sections can have welded flanges and can be supported about a vertical axis at the point where the wave "crosses" the mean direction of the pipeline.
