PE water supply pipe and PE gas pipe which is better quality?

Difference 1: The color of the pe gas pipe we usually see is a black pipe with a yellow vertical bar above it, and the 100 pe water supply pipe is a black pipe blue bar. Why do you want to mark different colors? I would say that everything is the same except for the difference in color and color, then you are very wrong, we will look down
Difference 2: Pe gas pipe asks because gas is transported, and gas friction will cause combustion and explosion, so the material used in pe gas pipe is added with an antistatic material, relatively speaking, the raw material price of pe gas pipe is cheaper than pe water pipe It's much higher.
Difference 3: Some people may say that the requirements of the PE gas pipe are higher than the requirements of the PE water pipe, then the PE gas pipe can be used as the PE water pipe, then it is very wrong, because the PE gas pipe and the PE water pipe The pressure bearing range of PE water pipe is different from PE gas pipe.
Difference four: The environmental standards of pe gas pipes and pe water pipes are also different. The pe water pipes can be used as cold water pipes for tap water pipes, but the pe gas pipes are not.
