Taking combined stainless steel plastic pipe and PPR pipe which was widely used in the secondary water supply system as research objects, we do a research of effect on water quality of these pipelines. These test indexes were divided into basic indexes and additional indexes. In addition, heterotrophic bacteria plate count was used to observe the attached bacteria on the inner wall of these two different pipes. The results showed that these two kinds of pipes are qualified for their hygienic safety as drinking water distribution equipments. The effects of pipe wall on water quality increased with the immersion time. Combined stainless steel plastic pipe is better than PPR pipe for less impact on water quality, less biofilm microbes attached, better stability, superior antibacterial effects. The combined stainless steel plastic pipe can give a better hygienic safety protection for drinking water.
