Product Description

PERT II Polyurethane Foam Flexible Pre-Insulated Pipe

High-Performance, Cost-Effective Heating Solutions for Direct Buried Systems

Product Overview

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.

• High Temperature Resistance: Tolerates up to 110°C, suitable for low-temperature heating systems (60°C supply, 45°C return).
• Smooth Pipeline: No impurities or pollution, ensuring high fluid efficiency.
• Automated Operation: Enables unattended, automated heating systems.
• Cost-Effective Construction: Reduces excavation by 40%, lowering installation costs.
• Material Savings: Up to 15% less material than PERT I and 30% less than PP-R pipes.
  

Features

• Flexible and Durable: Made with PE-RT II, offering corrosion resistance, scaling resistance, and low flow resistance.
• Advanced Insulation: Polyurethane foam (PPU) insulation minimizes heat loss, enhancing energy efficiency.
• Protective Sheath: LDPE outer sheath ensures long-term durability and protection.
• Wide Application: Suitable for direct buried heating systems below 90°C, including residential, commercial, and industrial uses.
• Eco-Friendly: Saves raw materials and reduces environmental impact.
