The present paper introduces the structural form of PE-RT pre-insulated pipes (PE-RT used as service pipes) for use as a substitute for steel pre-insulated pipes (steel pipe used as service pipes). The technical advantages of the PE-RT pre-insulated pipes when used in district heating are also illustrated. For pipes with the same diameter, length, and flow-rate, the pressure drop and transportation...
