Abstract:

This paper reported a comparative analysis on four types of engineering PVC pipes, including unplasticized PVC (PVC-U) water supply pipe, high performance unplasticized PVC (PVC-UH) water supply pipe, modified impact resistance PVC (PVC-M) water supply pipe, and oriented unplasticized PVC (PVC-O) water supply pipe. This analysis covered five aspects, including the technical requirements for compound, the allowable internal pressure and external pressure resistance capacity, the requirement for equipments, the requirement for performance, and the bell type. The advantages and application cases of PVC-UH pipeline were also summarized, and some practical suggestions for PVC-UH pipeline construction were proposed.

Key words: poly(vinyl chloride), water supply pipe, high performance, impact modification, biaxial orientation
