Insulated Pipe
Polyurethane Pre-Insulated Pipe
Steel carrier pipe, rigid polyurethane insulation, and a protective outer jacket for low-loss thermal transport.
Overview
Built for the application, not just the catalog
The system is engineered for district heating, geothermal energy, and hot or chilled water transmission. Foam density, jacket thickness, and leak detection options can be matched to the project.
Our pre-insulated pipe has been supplied to geothermal and municipal heating projects in Tibet and Shanxi, demonstrating performance in demanding climate conditions.
