Details

The raw material used for HDPE gas pipe is imported bimodal high density polyethylene pressure pipe special material. The special material for gas pipe is much slower than ordinary HDPE. It not only has excellent long-term compressive strength, but also has excellent resistance to slow stress cracking growth and rapid stress propagation, as well as excellent anti-draping performance. Fangsheng HDPE gas pipe has good resistance to high-speed cracking and expansion, which can ensure that the gas pipeline does not have accidental disasters.

Features:
1. Reliable connection: the polyethylene pipe system is connected by electric melting, 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 winter construction, due to the good impact resistance of the material, the pipe will not crack.
3. 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 prominent.
4. Good chemical corrosion resistance: HDPE pipeline can resist the corrosion of a variety of chemical media, and the chemical substances in the soil will not cause any degradation of the pipeline. Polyethylene is an electrical insulator, so there is no decay, rust or electrochemical corrosion.
5. Aging resistance and 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 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 longer service life and better economy.
7. Good flexibility: the flexibility of HDPE pipe makes it easy to bend, and the project can bypass obstacles by changing the direction of the pipe. In many occasions, the flexibility of the pipe can reduce the amount of pipe fittings and reduce the installation cost.
8. Convenient handling: HDPE pipe is lighter than concrete pipe, galvanized pipe and steel pipe, it is easy to handle and install, lower manpower and equipment requirements, which means that the installation cost of the project is greatly reduced.
