第 736 号

关于发布国家标准

《工业金属管道工程施工规范》的公告

现批准《工业金属管道工程施工规范》为国家标准，编号为 GB50235-2010，自 2011

年6月1日起实施。其中，第 1.0.5、8.6.1（2）、8.6.6（1）条（款）为强制性条文，

必须严格执行。原《工业金属管道工程施工及验收规范》GB50235-1997 同时废止。

本规范由我部标准定额研究所组织中国计划出版社出版发行。

前言

本规范是根据原建设部《关于印发<二 00 六年工程建设标准规范制订、修订计划

（第二批）>的通知》（建标[2006]136 号）的要求，由中国石油和化工勘察设计协会

和中国化学工程第三建设有限公司会同有关单位在《工业金属管道工程施工及验收规

范》GB50235-1997 的基础上修订完成的。

本规范在修订过程中，规范编制组经广泛的调查研究，认真总结实践经验，参考

有关国际标准和国外先进标准，并在广泛征求意见的基础上，修订本规范，最后经审

查定稿。

本规范共分 10 章和 1 个附录。主要技术内容是：总则，术语和符号，基本规定，

管道元件和材料的检验，管道加工，管道焊接和焊后热处理，管道安装，管道检查、检

验和试验，管道吹扫与清洗，工程交接等。

本规范修订的主要技术内容是：

1 在不适用范围中增加了石油、天然气、地热等勘探和采掘装置的管道，采暖通风

与空气调节的管道及非圆形截面的管道等。

2 增加了“符号”一节。

3 增加了管道分级的规定。

4 增加了管道组成件光谱分析的材质范围。

5 增加了安全阀应进行整定压力调整和密封试验的规定。

6 增补了斜接弯头、焊制翻边接头、支吊架制作的通用技术要求。

7 删除了部分“焊接”的通用技术要求。增补了法兰连接、支管连接的焊接要求。

8 增加了锆材有色金属管道、加套管和阀门安装的通用技术要求。

9 增加了焊缝射线和超声波检测的技术等级要求。

10 增加了“脱脂”一节。

本规范中以黑体字标志的条文为强制性条文，必须严格执行。

本规范由住房和城乡建设部负责管理和对强制性条文的解释，由中国工程建设标

准化协会化工分会负责日常管理，由全国化工施工标准化管理中心站负责具体技术内

容的解释。本规范执行过程中如有意见或建议，请寄送全国化工施工标准化管理中心

站（地址：河北省石家庄市桥东区槐安东路 28 号仁和商务 1-1-1107 室，邮编：050020），

以便今后修订时参考。
