标准摘要
[中文适用范围]： 本文件规定了一种推导压力降低系数的方法，以获得聚乙烯 (PE) 管道系统在 20 °C 至 40 °C 或 50 °C 温度下运行的允许运行压力，具体取决于所用材料的分类用于制造。 [外文原描述]： ISO 13761:2017 specifies a method for the derivation of pressure reduction factors to obtain the allowable operating pressure for operation of polyethylene (PE) pipeline systems at temperatures between 20 °C and 40 °C or 50 °C, dependent on the classification of the material used for manufacture.
