This standard replaces GB/T 13793-2008 “Steel pipes with a longitudinal electric (resistance) weld”. As compared with GB/T 13793-2008, the main changes are as follows. - MODIFY the scope of application; - MODIFY the allowable dimensional deviations; - MODIFY the allowable deviation of sizing length and length of double length; - MODIFY the weight conversion factor of galvanized steel pipe; - ADD the designation Q275, Q390, Q420, Q460; DELETE the designation Q295 AND its technical requirements; - DELETE the post-weld cold and hot working methods from the manufacturing method; - MODIFY the mechanical property requirements of Q195; - ADD the sampling methods and sampling locations for tensile test; - MODIFY the transverse tensile test requirements of welds; - MODIFY the non-destructive testing requirements of welds in steel pipes; - MODIFY the galvanized layer weight requirements; - MODIFY the conversion factor of the unit weight and thickness of galvanized layer. This standard was proposed by the China Iron and Steel Association. This standard shall be under the jurisdiction of the National Steel Standardization Technical Committee (SAC/TC 183). This standard was drafted by Zhejiang Jinzhou Pipeline Technology Co., Ltd., Tianjin Youfa Steel Pipe Group Co., Ltd., Tianjin Juncheng Steel Pipe Group Co., Ltd., Jinghua Innovation Group, National Petroleum and Natural Gas Pipeline Engineering Technology Research Center (Baoji Petroleum Steel Pipe Co., Ltd.), Anji Zhongyuan Pipe Industry Co., Ltd., Qian'an Zhengda Steel Pipe Co., Ltd., Metallurgical Industry Information Standards Institute. Steel pipes with a longitudinal electric (resistance) weld 1 Scope This standard specifies the classification and code, ordering content, size, shape, weight and allowable deviations, technical requirements, test methods, inspection rules, marking, packaging and quality certificates of the steel pipes with a longitudinal electric (resistance) weld. This standard applies to the steel pipes with a longitudinal electric (resistance) weld which is used for machinery, construction and other structural purposes, AND for which the outer diameter is not greater than 711 mm; it is also applicable to the welded steel pipes for general fluid delivery services. 2 Normative references The following documents are essential to the application of this document.
