The pipes produced by cross-linked polyethylene have the advantages of high creep strength, corrosion resistance, light weight and good heat resistance. The aluminum-plastic composite pipe made of cross-linked polyethylene has strong air tightness and high resistance to blasting stress. It has antistatic and shielding effect.
PEX pipe compared with PVC pipes and ordinary polyethylene pipes, cross-linked polyethylene pipes do not contain plasticizers, will not mildew and breed bacteria; do not contain harmful ingredients, meet FDA standards, and can be used for drinking water Pipe; heat resistance is good, the heat resistance of ordinary polyvinyl chloride and polyethylene pipe is 60-75 ℃, and the cross-linked polyethylene pipe is 90 ℃, the highest instantaneous temperature can reach 185 ℃, and can withstand low temperature of -75 ℃; use temperature The range is wide, and it can be used for a long time under the condition of -75-95°C, and the service life is as long as long-term durability according to standards. High cross-linking degree, high density, good pressure resistance; good chemical corrosion resistance, excellent environmental stress cracking resistance, can be used to transport a variety of chemicals even at higher temperatures Compared with stress materials with accelerated pipes , cross-linked polyethylene pipes are light in weight, only about 1/8 of metal pipes; they have good corrosion resistance and wear resistance. The wear rate is less than 1/4 of the steel pipe, and the service life is 2-6 times that of the steel pipe; the inner wall is smooth and the fluid flow resistance is small. When the pipe diameter is the same, the delivery flow is larger than that of the metal pipe, and the noise is much lower; the transmission performance is good , The transmission volume of liquid is 30%-40% higher than that of steel pipes; the thermal conductivity is much lower than that of metal pipes, so its thermal insulation performance is excellent. When used in a heating system, it does not need heat preservation, and the heat loss is small; it can be bent at will without brittle cracks; it has excellent electrical insulation performance, easy and easy installation, and the installation workload is less than half of that of metal pipes, and the installation cost is low.
Due to the excellent performance of pex pipe material. It is completely non-toxic and hygienic, so it has been regarded as a new generation of green pipes, mainly used in the following aspects:
(1) Building cold and hot water supply systems and pipeline drinking water systems;
(2) Air-conditioning and cooling water systems for buildings;
floor heating system
(3) Residential heating system;
(4) floor heating system;
(5) Piping of domestic water heater system;
(6) Pipelines for fluids such as beverages, alcohol, and milk in the food industry;
(7) Chemical and petroleum industry fluid delivery pipelines;
(8) Refrigeration system and water treatment system pipelines.
