The PERT national standard was developed with reference to international standards such as ISO's "Heat-Resistant Polyethylene (PE-RT) Piping Systems for Hot and Cold Water" and relevant parts of the Austrian national standard, while also taking into account domestic production conditions and technical capabilities. Therefore, it possesses a certain degree of advancement. The implementation of the new standard will have a positive impact on the quality requirements and healthy development of the industry.
PERT pipe is a thermoplastic heating pipe made from a special linear medium-density ethylene copolymer of ethylene and octene, with appropriate additives, and formed by extrusion. It has good flexibility, a small bending radius (five times the outer diameter), and unique "stress relaxation" properties, meaning it does not spring back after bending, facilitating installation. It also has good impact resistance and thermal stability, can be heat-fused for easy installation and maintenance, and has excellent molding and processing performance.
