前 言
本文件按照GB/T 1.1—2020《标准化工作导则　第1 部分：标准化文件的结构和起草规则》的规
定起草。
本文件代替GB/T 29038—2012《薄壁不锈钢管道技术规范》，与GB/T 29038—2012 相比，除编辑
性修改外，主要技术变化如下：
——更改了公称压力范围为不大于PN 25、公称尺寸范围为不大于DN 300（见第1 章，2012 年版
的第1 章）；
——增加了齿环卡压式连接的定义（见3.10）；
——增加了卫生间配水管布置要求（见5.1.9）；
——增加了建筑内抗震要求（见6.3.11）；
——增加了齿环卡压式连接方式要求（见6.4.6）；
——增加了不锈钢沟槽式连接方式要求（见6.4.11）；
——增加了附录G 不锈钢齿环卡压式连接规范要求（见附录G）；
——增加了附录L 不锈钢管沟槽式连接规范要求（见附录L）。
