压力管道判定中的疑难问题分析

Analysis of Difficult Problems in Determination of Pressure Piping

对压力管道判定中常见的疑难问题进行梳理和分析:诸如压力管道判定中涉及的非金属材料管道、介质的毒性、介质的腐蚀性、介质的可燃性等方面的问题,压力管道类别的问题、压力管道等级尤其是GC3级管道等问题。依据压力管道规范及标准对上述问题进行分析和归纳总结,为压力管道设计单位、使用单位以及监管机构提供参考。

In this paper,the common difficult problems in the determination of pressure piping are sorted out and analyzed,such as the determination of pressure piping involving non-metallic material piping,the toxicity of media,the corrosion of media,the flammability of media,the categories of pressure piping,the grade of pressure piping,especially the GC3 grade piping.According to the pressure piping codes and standards,the above problems are analyzed and summarized,which provides reference for pressure piping design units,users and regulatory agencies.
