Polyurethane Insulated Steel Pipe is a specialized piping solution combining a steel pipe core, polyurethane insulation layer, and outer protective jacket, designed for heat preservation during fluid transport. It is widely used in district heating systems, oil/gas pipelines (to prevent wax deposition), industrial process lines (hot water/steam), and solar thermal systems, where maintaining medium temperature is critical.
A key advantage of
Polyurethane Insulated Steel Pipe lies in its exceptional thermal insulation performance. The closed-cell polyurethane layer has low thermal conductivity (≤0.033 W/(m·K)), minimizing heat loss—reducing energy consumption by 30% compared to uninsulated steel pipes. This ensures transported media (e.g., 80–120°C heating water) retain temperature over long distances, enhancing system efficiency.
Polyurethane Insulated Steel Pipe further balances durability and practicality. Its steel core withstands high pressure (up to 4.0 MPa) and external impacts, while the outer jacket (e.g., polyethylene) resists corrosion from soil, moisture, and UV rays. The integrated structure simplifies installation, eliminating the need for separate insulation wrapping. Whether used in urban district heating networks or industrial hot fluid lines, it delivers reliable, energy-saving performance for temperature-controlled transport.
