We are pleased to deliver HDPE gas pipe and HDPE electrofusion fittings, HDPE Pipe Floats, if any doubt to the quality of our products, we will certify to deal with it within 24hours upon receiving the quality objection.
Features
1.Non-toxic.The HDPE material is non-toxic and tasteless.
2.Low flow resistance. The Smooth inner wall is easy for pipeline transportation .Under the same condition, HDPE pipe’s delivery capacity can be increased by 30%, as its roughness is much less than that of steel pipe and glass reinforced pipe.
3. No Leakage. HDPE pipe is connected in the ways of butt fusion, socket fusion and electrofusion, which means the strength of joint point is higher than tube itself .
4. Excellent Flexibility. HDPE pipes could be coiled for the small diameter products. Also, it could be slightly bended for the large diameter products, which will be much more convenient in the construction site.
5.Good resistance ability for scratch. HDPE pipe is 4 times the wear resistance of steel pipe, which means HDPE pipe has longer service life and better economical efficiency.
6.Convenient for construction. PE pipe could be installed in a variety of trenchless ways, so it is very convenient for construction and installation.
7.Long life-span. Designed 50 years’ service life under rated temperature and pressure.
8.Lower operation and maintenance costs. HDPE pipe is not only convenient to transport and install, but also greatly reduce the worker’s labor intensity and improve work efficiency.
Tengyuan can supply municipal engineering pipe, dredging engineering pipe, HDPE Gas Pipe, Power Engineering Pipe, Mining Pipe and agriculture irrigation pipe, etc. Integrity is the foundation of us, as well as the guarantee for enterprise's sustainable development.

Application:
HDPE gas pipe is suitable for the gas conveying pipe system whose operating temperature range from -20℃ to -40℃ and long time maximum working pressure no more than 0.7 MPA.
