前言

本文件按照GB/T1.1—2020《標準化工作導則第1部分：標準化文件的結構和起草規則》的規

定起草。

本文件代替GB/T29038—2012《薄壁不銹鋼管道技術規范》，與GB/T29038—2012相比，除編輯

性修改外，主要技術變化如下：

——更改了公稱壓力范圍為不大于PN25、公稱尺寸范圍為不大于DN300（見第1章，2012年版

的第1章）；

——增加了齒環卡壓式連接的定義（見3.10）；

——增加了衛生間配水管布置要求（見5.1.9）；

——增加了建筑內抗震要求（見6.3.11）；

——增加了齒環卡壓式連接方式要求（見6.4.6）；

——增加了不銹鋼溝槽式連接方式要求（見6.4.11）；

——增加了附錄G不銹鋼齒環卡壓式連接規范要求（見附錄G）；

——增加了附錄L不銹鋼管溝槽式連接規范要求（見附錄L）。
