GB 50251与ASME B31.8中输气管道试压规定的对比
发布时间：2019-07-26 10:31
【摘要】：管道试压是检验输气管道工程质量和保证管道安全的重要手段。GB 50251-1994《输气管道工程设计规范》对输气管道试压作了详细规定,是指导我国输气管道试压的最基础规范,该标准于2003年、2015年进行了修订。针对地区等级划分与设计系数选取、强度试验要求、严密性试验要求等管道试压关键问题,对GB 50251-2003、GB 50251-2015与ASME B31.8-2012《输气与配气管道系统》相关规定的差异进行了对比分析。结果表明:与采用0.8设计系数的ASME B31.8-2012相比,GB 50251-2015首次在一级一类地区采用0.8设计系数;在各地区等级沿线居民户数和(或)建筑物的密集程度的要求上,ASME B31.8-2012较GB 50251-2015更严格;在强度试验与严密性试验方面,GB 50251-2015对GB 50251-2003进行了补充和修改,降低了其保守性,但与ASME B31.8-2012相比仍然存在不全面之处。
[Abstract]:Pipeline pressure test is an important means to test the quality of gas pipeline engineering and ensure pipeline safety. GB 50251 / 1994 Code for Design of Gas Pipeline Engineering stipulates in detail the pressure test of gas pipeline, which is the most basic code to guide the pressure test of gas pipeline in our country. The standard was revised in 2003 and 2015. In view of the key problems of pipeline pressure test, such as the selection of regional grade classification and design coefficient, strength test requirements and tightness test requirements, the differences between GB 50251 2015 and ASME B31.8 2012 (Gas Transmission and Gas Distribution Pipeline system) are compared and analyzed. The results show that compared with ASME B31.8 / 2012 with 0.8 design coefficient, GB 50251 / 2015 adopts 0.8 design coefficient for the first class of areas for the first time, and ASME B31.8 / 2012 is more stringent than GB 50251 / 2015 in terms of the number of households and / or the density of buildings along each regional level. In terms of strength test and tightness test, GB 50251 / 2015 supplements and modifies GB 50251 / 2003, which reduces its conservatism, but it is still incomplete compared with ASME B31.8 / 2012.
