Advantages of PEX PPSU fittings

　　① The PEX PPSU fittings material is non-toxic, non-corrosive, non-scaling, and can effectively improve the water quality of the pipe network; it is resistant to chemical corrosion, internal, external and microbial corrosion, strong corrosion-resistance, and health; HDPE pipes have good water resistance The ability of hammer pressure, the fusion joint integrated with the pipe and the effective resistance of the HDPE pipe to underground movement and end load greatly improve the safety and reliability of water supply.

　　② It is easy to butt welding and electrofusion welding to form a closed anti-seepage system. When laying along the trench, it can reduce the amount of trench excavation and the number of accessories.

　　③ Lightweight and easy to install and handle;

　　④ With strong wear resistance and excellent hydraulic performance, no external protection is needed for buried pipelines. It can be applied to earthquake and soil settlement areas in mining areas, and it can also be laid at the bottom of rivers by the sinking method.

　　⑥ Good environmental adaptability and frost resistance. Can be used for indoor and outdoor water supply pipelines.

　　⑦ Long service life, with a service life of more than 50 years;

　　⑧ Easy to recycle.

　　PEX PPSU fitting not only has the characteristics of light material, good strength, corrosion resistance, and long service life of general plastic pipes but also non-toxic due to its characteristics (the molecule contains only two elements of hydrocarbon and hydrogen, which will not cause any damage to the human body. It is a well-deserved environmentally friendly and healthy material for poisonous use), does not rust, does not scale (the inner and outer walls are smooth, have strong corrosion resistance, and have little flow resistance to flowing liquid) heat resistance, antifreeze, heat preservation, The waste can be recycled and reused. Therefore, it can be used as cold and hot water pipes, pure water pipes, and drinking water pipes.

　　It also has the following main features:

　　① It is heat-resistant and heat-preserving and is an energy-saving product. The Vicat softening temperature of the PP-R pipe is 131.3℃, the higher operating temperature is 95℃, and the long-term (50 years) use temperature is 70℃. The thermal conductivity of this product is 0.24W/m℃, which is only 1 of the thermal conductivity of the steel pipe. /200, used for heat preservation and energy-saving effect of hot water pipe.

　　② The installation is convenient and reliable. The hot-melt connection can be used to complete a joint connection in a few seconds. The connection with the metal pipe and the water heater uses high-quality metal nickel-plated inserts, which is safe and reliable.

　　③ Easy to recycle.
