PE Pipe
- Anti-aging and long service life: The PE pipe containing 2-2.5% evenly distributed carbon black can be stored or used outdoors for 50 years without being damaged by ultraviolet radiation.
- Good wear resistance: The comparison test of the wear resistance of HDPE pipes and steel pipes shows that the wear resistance of HDPE pipes is 4 times that of steel pipes. In the field of mud transportation, HDPE pipes have better wear resistance than steel pipes. , Which means that HDPE pipes have a longer service life and better economy.
- Convenient handling: HDPE pipes are lighter than concrete pipes, galvanized pipes and steel pipes. It is easy to handle and install. Lower manpower and equipment requirements mean that the installation cost of the project is greatly reduced.
- A variety of new construction methods: HDPE pipelines have a variety of construction technologies. In addition to traditional excavation methods, a variety of new non-excavation technologies such as pipe jacking, directional drilling, and lining can also be used. It is the only choice for some places where excavation is not allowed. Therefore, HDPE pipelines are more widely used.
- Reliable connection: The polyethylene pipe system is connected by electric heating and the strength of the joint is higher than the strength of the pipe body.
- Good flexibility: The flexibility of HDPE pipeline makes it easy to bend. In engineering, obstacles can be bypassed by changing the direction of the pipeline. In many cases, the flexibility of the pipeline can reduce the amount of pipe fittings and reduce installation costs.
- Small water flow resistance: HDPE pipes have a smooth inner surface, with a Manning coefficient of 0.009. The smooth performance and non-adhesive characteristics ensure that HDPE pipes have a higher conveying capacity than traditional pipes, and at the same time reduce the pressure of the pipeline Losses and energy consumption for water delivery.
- 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℃. During winter construction, due to the good impact resistance of the material, pipe brittleness will not occur.
- Good stress cracking resistance: HDPE has low notch sensitivity, high shear strength and excellent scratch resistance, and its environmental stress cracking resistance is also very outstanding.
- Good chemical corrosion resistance: HDPE pipelines can withstand the corrosion of a variety of chemical media, and the chemical substances 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. Nevertheless, harmful substances will be released during combustion.
