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:
