- 对比分析了国内外主要管道试压规范,指出了GB50251-2003《输气管道工程设计规范》的不足,特别是此规范中没有对一、二级地区气试压的应用条件作具体规定。同时针对国内外试压规范均没有对现场气试压的安全预防范围进行定量规定的现状,为减少气试压时安全预防的盲目性,运用高压气体爆炸能量计算方法,以西气东输和忠武线为例,计算了气试压时管道爆破的损伤半径。为我国气试压规范的完善,特别是在一、二级地区气试压应用条件的制定,管材韧性分析,现场气试压的安全保护措施等方面提供了较有价值的参考依据。
Based on the comprehensive analysis of major codes for pipeline pressure test at home and abroad,the insufficiency of the Code for Design of Gas Transmission Pipeline Engineering (GB50251- 2003) is pointed out.In particular,this code does not contain specific provisions for applicative conditions of air test in Class One region or Class Two region.Meanwhile,under the situation that there have been no quantitative provisions of air test safety scope in relevant domestic and foreign codes,to reduce the safety blindness during air test,the damage radius of pipeline blasting is calculated by the computational method of high pressure air explosive energy with the examples of Zhongxian-Wuhan gas pipeline and West to East Pipeline.The study provides some valuable references for improving the domestic code relevant to air test,especially for establishing the air test applicative conditions and analyzing the pipe material toughness and making some field security measures of air test in Class one or Two region.2008,1(1): 5-8 收稿日期：2007-2-8分类号：TE973基金项目：中国石油天然气股份有限公司科学研究与技术开发项目(050304)作者简介：闫锋(1976-),男,河北定州人,2006年毕业于中国石油大学(北京),硕士研究生,现为该校在读博士研究生,从事油气储运系统安全工程的研究工作.参考文献：
