中国石油网消息：6月5日记者获悉，由中国金属材料流通协会标准化工作委员会归口管理，宝石管业宝世顺公司参与制定的《氢气输送用大口径不锈钢焊接钢管》团体标准正式发布实施。

China Petroleum News: On June 5th, it was learned that the "Group Standard for Large-Diameter Stainless Steel Welded Steel Pipes for Hydrogen Transportation", which was managed by the Standardization Work Committee of China Metal Materials Distribution Association and participated in the formulation by Baishoushun Company of Gemstone Pipe Industry, has been officially released and implemented.

该标准涵盖氢气输送用大口径不锈钢焊接钢管的分类、代号、外形尺寸、技术要求、试验方法、检验规则等内容，适用于公称直径168毫米及以上规格的钢管产品。

This standard covers the classification, code, external dimensions, technical requirements, test methods, and inspection rules of large-diameter stainless steel welded steel pipes used for hydrogen transportation. It is applicable to steel pipe products with a nominal diameter of 168 millimeters and above.

该标准特别针对气态氢环境下的慢应变速率拉伸试验、断裂韧度试验、疲劳寿命试验等项目明确了指标要求，为氢能不锈钢输送管道的生产制造与检测应用提供了权威的技术支撑。

This standard specifically sets out the index requirements for projects such as slow strain rate tensile tests, fracture toughness tests, and fatigue life tests in gaseous hydrogen environments. It provides authoritative technical support for the production, manufacturing, and testing application of hydrogen-based stainless steel pipeline transportation.
