Product Overview
Designed for district heating, cooling, hot water, and heat pump pipeline systems with operating temperatures up to 80°C.
Corrosion Resistance & Long Service Life
PERT-II pipes offer excellent corrosion resistance without additional anti-corrosion treatment, helping extend service life and reduce long-term maintenance costs.
Smooth Inner Wall & High Flow Efficiency
The smooth inner surface reduces friction resistance and prevents scaling, improving water transmission efficiency and ensuring more stable pipeline performance.
Cost-Effective & Easy Installation
Advanced polymer material technology makes small-diameter PERT-II pipes (below DN200) more economical than traditional seamless steel pipes, while the simple installation process reduces labor requirements and construction costs.
