Foreword

This standard was drafted in accordance with the rules given in GB/T 1:1-2009: This standard replaces GB/T 17268-2009 "Industrial Non-refillable Welded Steel Cylinders", compared with GB/T 17268-2009, except for The main technical changes outside of the editorial modification are as follows: ---Modified the scope of application of the standard (see Chapter 1, Chapter 1 of the:2009 edition); ---Modified the requirements for bottle body materials and welding materials (see 6:1:1, 6:1:3, 6:1:1, 6:1:3 of the:2009 edition); ---Added the welding method requirements for the pressure welding seam connecting the valve seat and the cylinder body (see 9:2:3); ---Added material verification test and wall thickness measurement requirements (see 10:1, 10:3:1); ---Modified the requirements of the air pressure test (see 10:2:2, 10:1:2 of the:2009 edition); ---Added the artificial aging requirements for the water pressure blasting test sample bottle (see 10:3:3:1); ---Modified the welding procedure qualification (see Appendix B, Appendix B of the:2009 edition); ---Modified the welder examination rules (see Appendix C, Appendix C of the:2009 edition); --- Added Appendix D "Yield Point Extension" (see Appendix D): This standard uses the redrafting method to refer to the edition of ISO 11118:2015 "Specifications and test methods for non-refillable metal gas cylinders for gas cylinders" The degree of consistency with ISO 11118:2015 is not equivalent: Please note that certain contents of this document may involve patents: The issuing agency of this document is not responsible for identifying these patents: This standard was proposed and managed by the National Gas Cylinder Standardization Technical Committee (SAC/TC31): Drafting organizations of this standard: Zhejiang Jucheng Steel Cylinder Co:, Ltd:, China Special Equipment Inspection and Research Institute, Shanghai Special Equipment Supervision and Inspection Technology Research Institute, Zhejiang Golden Elephant Technology Co:, Ltd:, Wuyi Xilinde Machinery Manufacturing Co:, Ltd:, Sanjiang Kaiyuan Co:, Ltd:, Zhejiang Ansheng Machinery Manufacturing Co:, Ltd:, Jiangsu Kaisidi Chemical Machinery Co:, Ltd: The main drafters of this standard: Huang Qianghua, Wei Chunhua, Xu Weipu, Lin Jianhua, Ye Xiaoru, Wang Yuhang, Zhu Zhenri, Tang Jianxiong, Lin Kangsheng, Shan Dongfang: The previous versions of the standard replaced by this standard are as follows: ---GB 17268-1998, GB/T 17268-2009: Industrial non-refillable welded steel cylinders

1 Scope

This standard specifies the type, design, manufacturing, inspection rules and test methods of industrial non-refillable welded steel cylinders (hereinafter referred to as steel cylinders) Method, marking, coating, etc: This standard is suitable for use at ambient temperature of -40℃~60℃, test pressure PT≤6:2MPa (gauge pressure), volume V≤ 25L, PTV≤100MPa·L (when PT >4:5MPa, V≤5L), non-refilling toxicity is classified as Class A refrigeration according to GB/T 7778 (Liquid gas at low pressure): Note: Steel cylinders must not be used to fill compressed gas:
