长输天然气管道试压研讨

Research on Pressure Test for Long Distance Natural Gas Pipeline

随着我国“西气东输”等高压、大口径、长输天然气管道的建设 ,如何参照国外经验并结合我国管道建设的实际 ,安全、经济、适宜地进行管道的试压 ,成为工程建设各方所共同关注的问题。文章通过对相关设计标准、制管要求的分析及对不同介质试压方式的比较 ,并以“西气东输”管道进行气压试验为例 ,对空气试压的可行性进行了计算研究 ,同时对试压操作提出了建议。

In construction of high pressure,large diameter,long distance gas pipelines,the involved parties commonly focus on safe,economic and reasonable pressure test.Taking West East Gas Pipeline pressure test with air for example,through analysis on relative design standards and piping requirements and comparison of pressure test methods with different media,researched is the feasibility of pressure test with air and suggestions are made to this pressure test method.
