摘　　要：介绍硬质聚氯乙烯(PVCU)管材的优点,结合工程实践指出了PVCU管在给排水工程应用中应注意的问题,如提高使用寿命、降低噪音、防止返气、减少变形、避免渗漏等,展望了PVCU管的应用前景。The merits of unplasticized poly(vinyl chloride)(PVC-U) pipe were described. Several problems such as raising service life, reducing noise, preventing gas-returning, decreasing distortion, and avoiding leakage which should be noticed when PVC-U pipe was used in water supply and drain were pointed out, combining with the engineering practice. The application prospect of PVC-U pipe was expected.
