摘要:

首先概述了长期静液压强度的2种预测方法(ISO 9080和ASTM D 2837)的原理、数据要求和处理、外推计算和结果应用等方面的异同点,进一步分析在2种标准体系下高密度聚乙烯(PE-HD)管道最大工作压力(MOP)的计算程序和结果,为在不同应用领域的管道设计和应用提供理论参考。

关键词: 材料分级, 长期静液压强度, 设计因子, 最大工作压力

Abstract:

This paper summarized and compared test principles, data requirements and extrapolation calculation of two test methods, ISO 9080 and ASTM D 2837, for PE-HD pipes. The calculation process of maximum operating pressure of PE-HD pipes under these two standard systems was further analyzed, which can provide a theoretical reference of design for pipeline in different applicable areas.

Key words: material classification, long-term hydrostatic strength, design factor, maximum operating pressure
