Product Description

HDPE pipe is a pipe made of high-density polyethylene (English name "High-Density Polyethylene", referred to as "HDPE").

HDPE pipe is the replacement product for traditional steel pipe and PVC drinking water pipe.

HDPE pipes must withstand a certain pressure, and PE resins with large molecular weight and better mechanical properties, such as HDPE resins, are usually selected. LDPE resin has low tensile strength, resistance to pressure difference, poor rigidity, poor dimensional stability during molding, and difficult connection, and is not suitable as a material for water supply pressure pipes. However, due to its high hygienic index, LDPE, especially LLDPE resin, has become a common material for the production of drinking water pipes. LDPE and LLDPE resins have low melt viscosity, good fluidity, and easy processing, so the selection range of their melt index is also wide, usually, MI is between 0.3-3g/10min.

All HDPE pipes provided by our factory are made of 100% virgin materials, and the production standard conforms to the ISO4427 standard.

HDPE is a kind of good pipeline, it should not only have a good economy but also have a series of advantages such as stable and reliable interface, material impact resistance, crack resistance, aging resistance, corrosion resistance, etc. Compared with traditional pipes, the HDPE pipeline system has The following series of advantages:
(1) Reliable connection: The polyethylene pipe system is connected by electrothermal fusion, and the strength of the joint is higher than that of the pipe body.
(2) Good low-temperature impact resistance: The low-temperature embrittlement temperature of polyethylene is extremely low, and it can be used safely in the temperature range of -60-60 °C. During construction in winter, due to the good impact resistance of the material, the pipe will not be brittle.
(3) Good resistance to stress cracking: HDPE has low notch sensitivity, high shear strength and excellent scratch resistance, and its resistance to environmental stress cracking is also very outstanding.\
(4)Good chemical corrosion resistance: HDPE pipes are resistant to corrosion by a variety of chemical media, and chemical substances in the soil will not cause any degradation to the pipes. Polyethylene is an electrical insulator, so it does not rot, rust or electrochemically corrode; it also does not promote algal, bacterial, or fungal growth.
(5)Aging resistance, long service life: polyethylene pipes containing 2-2.5% evenly distributed carbon black can be stored or used outdoors for 50 years without being damaged by ultraviolet radiation.
(6)Good wear resistance: The comparison test of wear resistance of HDPE pipe and steel pipe shows that the wear resistance of HDPE pipe is 4 times that of steel pipe. In the field of mud transportation, compared with steel pipes, HDPE pipes have better wear resistance, which means that HDPE pipes have a longer service life and better economy.
(7)Good flexibility: The flexibility of HDPE pipes makes them easy to bend, and in engineering, obstacles can be bypassed by changing the direction of the pipes. n many occasions, the flexibility of pipes can reduce the number of pipe fittings and installation costs.
(8)Small water flow resistance: HDPE pipe has a smooth inner surface, and its Manning coefficient is 0.009. The smooth performance and non-adhesive properties ensure that the HDPE pipe has a higher conveying capacity than traditional pipes, and also reduces the pressure loss of the pipeline and the energy consumption of water conveying.
(9) Easy to handle: HDPE pipes are lighter than concrete pipes, galvanized pipes and steel pipes. They are easy to handle and install, and lower manpower and equipment requirements mean that the installation cost of the project is greatly reduced.
(10)Various new construction methods: HDPE pipes have various construction techniques. In addition to traditional excavation methods, various new trenchless techniques such as pipe jacking, directional drilling, lining, It is a good choice for some places where excavation is not allowed.
