In district heating networks, heat loss along the pipeline directly affects operating cost. Pre-insulated steel pipes address this with a rigid polyurethane foam layer between the steel carrier pipe and an HDPE outer jacket.
The polyurethane foam used in pre-insulated pipes has low thermal conductivity, keeping heat loss to a designed level over long distances. For high-temperature steam lines, steel-jacketed insulation pipes with aluminum silicate or composite insulation are used instead.
Key parameters to confirm when ordering: carrier pipe size and standard, insulation thickness, jacket thickness, service temperature and joint treatment method on site.
Cangzhou Youcheng Pipeline supplies polyurethane pre-insulated pipes and steel-jacketed steam insulation pipes with matching insulation fittings for complete network packages.
