PP-R hot and cold water pipes are made of random copolymer polypropylene, which is hygienic and non-toxic, heat-resistant and corrosion-resistant, has a smooth inner wall that does not scale or breed bacteria; it can withstand 70°C in the long term and can withstand high temperatures of 95°C in the short term. The hot-melt connection is formed in one piece, does not leak, is maintenance-free, and has a service life of more than 50 years.

It is easy to install, green and environmentally friendly. It is suitable for domestic hot and cold water supply, heating and central air-conditioning water circulation systems in residential buildings, hotels, hospitals, schools and other buildings. It is the preferred water supply pipe for modern buildings.

• Excellent high temperature resistance, suitable for hot and cold water supply systems

  Made of random copolymer polypropylene, the long-term hot water use temperature is 70°C, and the instantaneous high temperature resistance can reach 95°C. It can be used for both hot and cold water;

  Comply with GB/T 18742, ISO 15874, DIN 8077, DIN 8078, ASTM F2389

• Hygienic, safe and non-toxic, can be used for direct drinking water transportation
  

  Food grade PP‑R raw material, no heavy metals, no harmful substances precipitated, no bacteria breeding, ensuring drinking water safety;

  Comply with GB 4806.7, NSF/ANSI 61, KTW

• Good thermal insulation performance, energy saving and consumption reduction

  The thermal conductivity is low, and the heat loss in hot water transportation is small, which reduces energy waste and reduces the problem of condensation and dripping in pipelines;

• Corrosion-resistant and non-scaling, long-term stable water quality

  Resistant to acid, alkali, scale and microbial corrosion, the inner wall is smooth and not easy to scale, the pipe diameter remains unchanged and the water flow is stable during long-term use;

  Complies with ISO 4433, EN 12573, DIN 50929

• The hot-melt connection is integrally formed, with zero leakage and no water leakage.

  Hot melt socket connection, the pipe and fittings are melted into a whole, the strength of the interface is higher than that of the pipe body, eliminating the risk of leakage;

  Complies with DVS 2207, EN 12814, DIN 16928

• High toughness, impact resistance and water hammer resistance

  It is resistant to water hammer impact and has good low-temperature toughness. It can be used in normal construction at ‑20℃ and is not easy to crack or burst;

  Complies with EN 1046, ISO 13479, DIN 8077

• Complete pressure levels to meet water supply in multiple scenarios

  S5‑S2.5 multi-series specifications are suitable for high-pressure hot and cold water supply in home decoration, hotels, hospitals, floor heating, and industrial equipment;

  Comply with GB/T 18742, ISO 15874, DIN 8078

• Light weight, convenient and efficient home decoration construction

  The material is light and easy to cut, and the installation is flexible. It is suitable for small space layouts such as concealed ceilings, tube wells, etc.;

• Insulated and flame retardant, safe and reliable to use
  

  It has excellent insulation performance and is not easy to conduct electricity; it can be adapted to flame retardant modification and complies with the safety and fire protection regulations for indoor water supply in buildings;

• Super long service life and low operation and maintenance costs

  The service life of normal temperature cold water pipes is ≥50 years, and the hot water pipes are ≥25 years. They are maintenance-free and are widely used in home decoration, construction, and commercial water supply;

  Comply with GB 50235, AWWA C906, DIN 4124
