摘　　要：从混配料技术要求、允许内压及抗外压能力、设备要求、性能指标要求及接口形式5个方面分别介绍并对比了硬聚氯乙烯(PVC-U)给水管、高性能硬聚氯乙烯(PVC-UH)给水管、抗冲改性聚氯乙烯(PVC-M)给水管及双轴取向聚氯乙烯(PVC-O)给水管4种硬质聚氯乙烯管材,并重点总结了PVC-UH管道的选取优势和应用案例,最后针对PVCUH管道的施工给出了实践性建议。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 PVCUH pipeline construction were proposed.
