摘　　要：随着我国对安全生产及环境保护的高度重视,对化工工艺管道的设计和化工系统运行安全提出更高的要求,文章从管道材质、分级、柔性、支架和泄露试验等5个方面对化工管道设计进行系统分析,对标国家对化工工艺管道泄漏试验规定,提出采用试验压力不小于105 kPa或25%设计压力(取较小值)的敏感性泄漏试验方法较为符合管道泄漏试验现状,为化工工艺管道设计和泄漏试验提供理论依据。As China attaches great importance to safe production and environmental protection,higher requirements are put forward for the design of chemical process pipelines and the safety of chemical system operation.This article summarized the key points of chemical pipeline design from five aspects,analyzed and studied the national regulations on leakage test of chemical process pipelines,It is proposed that the sensitivity leakage test method with the test pressure not less than 105kPa or 25%of the design pressure(whichever is smaller)is more consistent with the current situation of pipeline leakage test,which provided a theoretical basis for the design and leakage test of chemical process pipelines.
