PE Pipe
Application
Our PE pipe is suitable for delivering water, natural gas, coal oven gas, ore sand and mud slurry in cities, food and chemical industry. It can also serve as replacement for cement pipe, cast iron pipe, steel pipe and landscape water supply pipe.
Features
1. The PE pipe we produce has excellent erosion resistance and will work well even when the temperature falls sharply.
2. With high strength and flexibility, our polyethylene pipe is of high adaptive capacity to uneven foundations and is resistant to earthquake and typhoon.
3. Our product features good weather fastness (anti-UV) and long-term thermal stability.
4. You do not need to take special consideration about the surroundings, water quality or soil quality when you lay the pipelines since our PE pipes are highly resistant to inorganic salt, inorganic acid, alkali metal, organic matter and other corrosive chemical substances.
5. Thanks to smooth inner wall, our PE water pipe has low flow resistance and high flow capacity, thereby helping reduce construction cost.
6. Our PE pipe is applicable for both traditional excavation construction mode and new trenchless construction mode such as pipe-jacking, directional drilling, pipe lining, pipe cracking and water sinking.
7. The PE material we use only contains the carbon and hydrogen elements. Hence, our PE gas pipe is environmentally friendly and non-toxic. It is completely in conformity with the national standard.
8. As a trustworthy pipe system suppler, we can offer you polyethylene pipes which are durable and have long lifespan.
