Abstract: Tthe new products included modified polyvinyl chloride(PVC-M) pipe, biaxial orientation polyvinyl chloride(PVC-O) pipe, polypropylene of raised temperature resistance(PE-RT) pipe, β-PP-R pipe, and Ultrahigh molecular weight polyethylene(PE-UHMW) pipe of plastic pipe industry in China were summarized. The features and application fields of composite metal/plastic pipe and composite plastics/plastic pipe were introduced,. In addition, some new piping system were described in detail, especially for the advantages when they were applicated in the new building technology. In the final, the analysis and prospect of plastic pipes industry in China were made in combination with national industrial policies as well.
