HDPE Water Service Pipe

Description

Product Information：

This HDPE Water Service Pipe is a water pipe under IFAN. It is a pipe made of high-density polyethylene (referred to as "HDPE"), which is a replacement product of traditional steel pipes and PVC drinking water pipes.

HDPE Water Service Pipe must withstand a certain pressure, usually PE resin with large molecular weight and better mechanical properties, such as HDPE resin, should be used. 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.

Product Features:

As a high-quality pipe, HDPE Water Service Pipe should not only have 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, HDPE pipes The system has the following series of advantages:

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; good impact resistance at low temperature: the low temperature embrittlement temperature of polyethylene is extremely low, which can be in the temperature range of -60-60℃ Safe use, in winter construction, due to the good impact resistance of the material, the pipe will not be brittle; good stress crack resistance: HDPE has low notch sensitivity, high shear strength and excellent scratch resistance, environmental resistance Stress cracking performance is also very outstanding; good chemical corrosion resistance: HDPE Water Service Pipe is resistant to corrosion by a variety of chemical media, and the chemicals present in the soil will not cause any degradation to the pipeline. Polyethylene is an electrical insulator, so it will not rot, rust or electrochemical corrosion; in addition, it will not promote the growth of algae, bacteria or fungi; aging resistance, long service life: contains 2-2.5% of evenly distributed Carbon black polyethylene pipes can be stored or used outdoors for 50 years without being damaged by UV radiation.

Good wear resistance: The comparison test of wear resistance between HDPE Water Service 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 longer service life and better economy; good flexibility: the flexibility of HDPE Water Service Pipe makes It is easy to bend, and in engineering, it can bypass obstacles by changing the direction of the pipeline. In many occasions, the flexibility of the pipeline can reduce the amount of pipe fittings and installation costs; the water flow resistance is small: the HDPE Water Service Pipe has a smooth inner surface. The Manning coefficient is 0.009. Smooth performance and non-adhesive properties ensure that HDPE pipes have higher conveying capacity than traditional pipes, and also reduce the pressure loss of pipes and energy consumption for water conveying; easy handling: HDPE Water Service Pipe is better than concrete pipes and galvanized pipes. And the steel pipe is lighter, it is easy to handle and install, and the lower manpower and equipment requirements mean that the installation cost of the project is greatly reduced; a variety of new construction methods: HDPE pipes have a variety of construction techniques, in addition to the traditional open In addition to the excavation method for construction, a variety of new trenchless technologies such as pipe jacking, directional drilling, lining pipe, cracking pipe, etc. can be used for construction, which is a good choice for some places where excavation is not allowed.
