摘要
介绍了《输气管道工程设计规范》GB 50251-2003关于试压条款的内容、制定和修订主要依据及背景,与美国联邦法规49CFR 192和美国机械工程师协会标准ASME B31.8以及ISO、加拿大、英国及欧洲等国际标准相关条文进行了详细对比,同时对国标GB 50251-2003关于试压的条款提出了修订建议,对于我国天然气管道试压技术研讨和工程设计工作有一定的参考价值。
Described are pressure test requirements in the Chinese standard 'Specification for Gas Transmission Pipeline Engineering Design' GB 50251-2003,the background and main references upon which the test requirements have been made.A detail comparison is made with the Federal Regulation 49 CFR 192 and the Industry Code ASME B31.8 of USA,as well as ISO,Canadian,British,European pipeline standards and some amendment suggestions on the test requirements are given,which are beneficial to gas pipeline pressure test technology development and pipeline engineering design in China.
