摘要
介绍了在聚丙烯给水管道设计中 ,应根据工程使用性质、运行水温及其频率确定使用条件等级及Scalc,max的计算方法。并确定了根据Scalc,max值选择管系列S值的原则 ,从而确定管材壁厚的大小。
In this paper according to engineering operation characters, operational water temperature and its frequency the determining method of operational grade and calculation method of S value are introduced for polypropylene water supply pipeline's design. At the same time the principle of choosing pipeline according to S value is established to determine the value of tube wall.
