Piping Technology
Pipe systems, network structure, laying methods and thermal expansion
Piping technology covers the physical realization of a heat network – from the choice of pipe system and network structure to laying and statics. Material selection, insulation standard and laying method affect heat losses, thermal expansion and the service life of the route. This topic area compares pipe systems and addresses network topology, civil works and structural design.
