The remarkable characters of PE gas pipe
◇ Permanently using life-PE pipe can be used for more than 50years safely under the rated temperature and pressure.
◇ Good corrosion-resistant-except a few strong oxidizings.It is corrosion-resistant to many chemical medium.and no electric chemical corrosion.
◇ Good flexibility-PE pipe can be rolled or coiled.
◇ Quite good impact-resistant-PE pipe has good flexibility and impact-resistant that it won't be broken when heavy object presses on it.
◇ Reliable joining the seam of joining won't be cracked due to the moving of soil or load because the strength of the heat or elect-melted inlerface is stronger then the PE pipe it self.
◇ Convenient for installation-the pipeline has a light weight,Simply welding skill.Convenient for installation and a lower cost of the project.
