浅谈化工设计中工业金属管道等级划分

Brief Discussion of Industrial Metal Pipeline Classification in Chemical Engineering Design

现行国家和行业标准对化学工业金属管道分级分为压力管道和石油化工金属管道两个体系。通过对两个体系流体类别分类、管道等级划分、无损检测进行梳理,有助于设计、施工、检验等工程技术人员对工业管道分级体系有更深刻的理解,能在实际工作中正确应用管道分级的方法。

Chemical industrial metal pipelineclassification contains the pressure pipelineand petrochem- ical metal pipeline in the current national and industrial standards. Fluid category, piping classification,non- destructive testing in the two systems were combed, whichare helpful for engineering and technical personnel to have a more profound understanding and classify chemical industrial metal pipeline correctly in engineering application.
