isoplus pre-insulated steel pipes are fixed pipe systems consisting of a steel carrier pipe, polyurethane insulation and an HDPE jacket pipe that is moulded into a fixed sandwich construction.
Insulation of steel pipes
isoplus steel pipes are insulated with polyurethane foam that is blown with cyclopentane. This provides optimum insulation value and high compressive strength. Our steel pipes are supplied at a continuous operating temperature of 143 °C for single pipes and 130 °C for double pipes.
On request we can supply steel pipes that can withstand continuous operating temperatures of up to 161 °C.
If you wish to monitor the district heating system electronically, isoplus steel pipes can be supplied with two bonded copper wires for connection to the alarm system. For example isoAlarm.
