High-Performance, Cost-Effective Heating Solutions for Direct Buried Systems
Our PERT II Polyurethane Foam Flexible Pre-Insulated Pipe, also known as Type II Heat-Resistant Polyethylene (PE-RT II) Low-Temperature Direct Buried Heating Pipe, is designed for efficient and durable heating solutions. With a smooth pipeline, high temperature tolerance, and advanced insulation, it is ideal for modern heating systems, including underfloor heating, district heating, and industrial applications.
PERT II pipes offer significant material savings compared to PERT I and PP-R, reducing costs while maintaining performance. The table below compares wall thickness and weight for different pipe diameters at a design pressure of 10 Bar.
| Diameter (mm) | Pipe Type | Series | Wall Thickness (mm) | Wall Thickness Area (m²) | Density (kg/m³) | Length (m) | Weight (kg) | Weight Savings |
