HDPE Pipe Features

HDPE is a good pipeline, not only should have good economy, but also should have a stable and reliable interface, material impact resistance, cracking resistance, aging resistance, corrosion resistance and a series of advantages, compared with the traditional pipe, HDPE pipeline system has the following series of advantages:

(1) Reliable connection: polyethylene pipe system is connected by electric heating, and the strength of the joint is higher than the strength of the pipe body.

The low temperature impact resistance is good: the low temperature embrittlement temperature of polyethylene is very low, and it can be used safely in the temperature range of -60-60℃. In winter construction, the pipe will not crack due to the good impact resistance of the material.

⑶ Good stress cracking resistance: HDPE has low notch sensitivity, high shear strength and excellent scratch resistance, and environmental stress cracking resistance is also very outstanding.

(4) Good chemical corrosion resistance: HDPE pipeline can be resistant to corrosion of a variety of chemical media, the presence of chemicals in the soil will not cause any degradation of the pipeline. Polyethylene is an electrical insulator, so it will not rot, rust or electrochemical corrosion; It also does not promote the growth of algae, bacteria or fungi.

⑸ Aging resistance, long service life: polyethylene pipe containing 2-2.5% uniform distribution of carbon black can be stored outdoors or used for 50 years, will not be damaged by ultraviolet radiation.

⑹ Wear resistance: THE wear resistance of HDPE pipe and steel pipe comparison test shows that the wear resistance of HDPE pipe is 4 times that of steel pipe. In mud transportation, HDPE pipes offer better wear resistance compared to steel pipes, which means longer service life and better economy.

High flexibility: The flexibility of the HDPE pipe makes it easy to bend and can be used to bypass obstacles by changing the direction of the pipe. In many cases, the flexibility of the pipe can reduce the amount of pipe fittings and installation costs.

⑻ Low flow resistance: THE HDPE pipe has a smooth inner surface and a Manning coefficient of 0.009. The smooth performance and non-adhesive characteristics of HDPE pipes ensure higher delivery capacity than conventional tubing, while reducing pressure loss and water consumption.

(9) Easy handling: HDPE pipe is lighter than concrete pipe, galvanized pipe and steel pipe. It is easy to handle and install, and requires less manpower and equipment, which means the installation cost of the project is greatly reduced.

We will also introduce a variety of new construction methods: HDPE pipeline has a variety of construction technology, in addition to the traditional way of excavation construction, can also use a variety of new trenchless technology such as pipe jacking, directional drilling, lining, cracking pipe and other ways of construction, which is not allowed for some places of excavation, is a good choice
