PE pipe inner wall is smooth with features of low friction resistance and energy saving and does not change with the use of time.Its pressure loss is about *0% smaller than steel pipe, therefore,smaller pe pipe is a better way than steel pipe.PE pipe has good hygienic performance with no additives, so it is impossible to pollute the drinking water.Polyethylene material level is 0 (the lowest level) in ISO standard and it is moldy material. Compared with other commonly used plastic materials,mildew resistance of polyethylene is much higher resulting a long term use without scaling.
