Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
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.,

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.
