HDPE Gas Pipes

HDPE Gas Pipeline

HDPE gas pipes are made of high-density polyethylene material, which has good corrosion resistance, aging resistance, wear resistance and high ﬂexibility. These characteristics make HDPE pipes a high-quality choice in the field of gas transmission, especially in the construction of urban gas pipeline networks.

product details

FeaturesFeatures

1. Non-toxic. HDPE material is non-toxic and tasteless.

2. Low flow resistance. The inner wall is smooth, the pipeline is convenient, and the conveying capacity of HDPE pipe can be increased by 30% under the same use environment, and its roughness is much smaller than that of steel pipe and glass fiber reinforced pipe.

3. No leakage. HDPE pipes are connected in hot melt butt, socket butt, and electric fusion, which means that the strength of the connection points is higher than the pipe itself.

4. Strong flexibility. Small-diameter bright density polyethylene pipes can be coiled, and large-diameter pipes can also be slightly bent, which is more convenient for construction.

5. Good flex resistance. The wear resistance of HDPE pipe is 4 times that of steel pipe, which means that HDPE pipe has a longer service life and is more economical and practical.

6. Convenient construction. PE pipes can be installed in various trenchless projects, which is convenient for construction and installation.

7. Long life. It has a practical life of 50 years at rated temperature and pressure.

8. Reduce operation and maintenance costs. High-density polyethylene pipes are not only convenient for transportation and installation, but also greatly reduce the labor intensity of workers and improve work efficiency.
