Application of High Density Polyethylene Pipe (HDPE) in Same Floor Drainage System

This paper analyses the technology characteristics of HDPE pipes and UPVC pipes that used in drainage. Using a residential building project in Hangzhou as an example, it compares the economic benefits and comprehensive benefits of HDPE pipes with those of UPVC pipes. It concludes that it’s better to use HDPE pipes in same floor drainage system, and the using of HDPE pipes will bring benefits in the promoting of the same floor drainage system.
