Advantages of HDPE Piping System
- Sep 20, 2018 -


HDPE piping system advantages:


1. Reliable connection: The polyethylene pipe system is connected by electric hot melt method, and the strength of the joint is higher than the strength of the pipe body.

2. low temperature impact resistance: polyethylene low temperature embrittlement temperature is very low, can be safely used in the temperature range of -60-60 °C. In winter construction, due to the good impact resistance of the material, the tube will not be brittle.

3. good resistance to stress cracking: HDPE has low notch sensitivity, high shear strength and excellent scratch resistance, and environmental stress cracking resistance is also very prominent.

4. good chemical resistance: HDPE pipeline can withstand the corrosion of a variety of chemical media, the chemical substances in the soil will not cause any degradation of the pipeline. Polyethylene is an electrical insulator and therefore does not rot, rust or electrochemically corrode; it also does not promote the growth of algae, bacteria or fungi.

5. anti-aging, long service life: Polyethylene pipes containing 2-2.5% of uniformly distributed carbon black can be stored or used outdoors for 50 years without damage from UV radiation.

6. Good wear resistance: The comparison 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 transport, HDPE pipes have better wear resistance than steel pipes, which means HDPE pipes have a longer service life and better economy.

7. Good flexibility: The flexibility of the HDPE pipe makes it easy to bend. In engineering, the obstacle can be bypassed by changing the direction of the pipe. In many cases, the flexibility of the pipe can reduce the amount of pipe fittings and reduce the installation cost.

8. Low water flow resistance: The HDPE pipe has a smooth inner surface with a Manning coefficient of 0.009. The smooth performance and non-adhesive properties ensure that the HDPE pipe has a higher conveying capacity than conventional pipes, while also reducing the pressure loss and water consumption of the pipe.

9. Convenient handling: HDPE pipes are lighter than concrete pipes, galvanized pipes and steel pipes. They are easy to handle and install. The lower manpower and equipment requirements mean that the installation cost of the project is greatly reduced.

10. A variety of new construction methods: HDPE pipelines have a variety of construction techniques. In addition to traditional excavation methods, a variety of new non-excavation techniques such as pipe jacking, directional drilling, and liners can be used. Construction in the form of split pipes, etc., which is a good choice for some places that are not allowed to be excavated, so HDPE pipelines are more widely used.
