输气管道站场气体严密性试验方法的比较

Comparison Of gas test method on leakage in The gas transmission Pipeline station

输气站场施工过程中必须进行气体严密性试验,通过比较现有的3种气体严密性试验方法、试压介质、试验设备,分析试验方法的经济性和适用性,本文结合实践对气体严密性试验方案进行了总结。

In the course of gas transmission station construction,gas test on leakage must be carried out.By comparing the three existing gas test methods on leakage,test material l,and test machine,the economy and applicability of the test methods are analyzed,this paper concludes some construction methods for gas test on leakage in The gas transmission Pipeline station on the basis of engineering practice.
