Octal HDPE Pipes

Good chemical corrosion resistant performance Polyethylene is an inert material and resistant to erosion of many chemical media. It doesn’t have electrochemical corrosion and does not need anti-corrosion coating. Chemical substances present in the soil will not cause any degradation of the pipe. In addition, it will not promote growth of algae and bacteria.
Good anti-stress and cracking performance Polyethylene has low notch sensitivity, high anti-shearing strength and excellent capabilities in its resistance to trace; moreover its performance in anti environmental stress and cracking are also very prominent.
Good low-temperature impact brittleness Polyethylene’s low brittle temperature is very low and is can be used safely at the temperature range of -200Cto +400C.During winter construction, brittle rupture of the pipe will not occur due to its good anti impact performance.
Good wearing resistant performance The anti-wearing comparison test between polyethylene pipe shows that wearing resistant performance of polyethylene pipe is 4 times of steel pipe. In the fields of slurry transportation, polyethylene pipe has better wearing resistant performance compared to steel pipe which means polyethylene pipe possesses longer service life and better economy.

Anti-aging and long service life PE pipe with 2%-2.5% uniformly distributed carbon black can effectively shield UV rays and will not suffer damage resulted by ultraviolet radiation. Service life of 50 years can be ensured.
High toughness Polyethylene pipe is a kind of pipe with toughness; its broken elongation rate generally surpasses 500%; its ability to adapt to uneven subsidence of foundation is very strong. It is also an excellent pipeline with good antiseismic performance.
Good flexibility of polyethylene is a key performance indicator, which shows the material’s value to the pipeline project. Flexibility of polyethylene make the polyethylene pipe can be coiled and supplied with relatively long length while don’t need various connecting pipe fitting. In many occasions, the pipe’s flexibility can reduce the amount of used pipes and the installation costs.
Polyethylene pipe has good ability to resist scratches Studies show that polyethylene with PESO grade has relatively good ability in resisting SCG and scratches. While the polyethylene with PE100 grade has much excellent ability in resisting scratches.
