Smart Controlled PERT PU Foam Pipe Extrusion Line for Long Life Thermal Insulation Pipes
The polyurethane PERT pre-insulation pipe—internationally known as a flexible pre-insulated pipe—is defined in Chinese standards as Type II Heat-Resistant Polyethylene (PE-RT II) Low-Temperature Direct-Buried Heating Pipe.
This production line adopts a one-step continuous foaming process, ensuring stable performance, high production efficiency, and long-term reliability for district heating applications.
Smart Controlled PERT PU Foam Pipe Extrusion Line with One-Step Continuous Foaming Process
Key Features
Superior Thermal Performance
  • High Temperature Resistance: PERT II pipes can tolerate temperatures up to 110°C, ensuring reliable performance in high-temperature heating systems.
  • Efficient Heat Transfer: With a 60°C supply water and 45°C backwater temperature, these pipes meet heating demands efficiently, reducing energy consumption and costs.
Quality and Safety
  • Smooth and Pure Surface: The pipeline is smooth, free from impurities, and non-polluting, ensuring a clean and safe heating environment.
  • Automated Operation: Heating companies can achieve unattended, automated operation, reducing labor costs and increasing operational efficiency.
Construction Advantages
  • Simplified Construction: The construction process is simple and convenient, with a 40% reduction in excavation volume, greatly reducing construction costs and time.
  • Material Savings: Compared to traditional materials like PERT I and PP-R, PERT II pipes offer significant material savings. For example, compared to PERT I, PERT II can reduce material use by 15%, and compared to PP-R, it can reduce material use by 30%.

Product Parameters
It saves raw materials for using PE-RT II pipe.
Example: Level 2 design pressure: 10 Bar; for cold and hot water transfer in buildings
Selection of different material pipes: the highest PE-RTIIS value; the thinnest wall thickness
  • Compared to PERT I, PERT II can reduce material use by 15%
  • Relative to PP-R, PERT II can reduce material use by 30%
Note: According to relevant Chinese national standards and draft
