Foreword
This Standard is revised by reference to ASTM A53/A53M-05 "Standard Specification
for pipe, steel, Black and Hot-Dipped, zinc-Coated, Welded and Seamless" and JIS G
3444.2004 "Carbon steel tubes for general structural purposes".
This Standard replaces GB/T 13792-1992 "Welded steel pipe for supporting roller of
belt conveyer" and GB/T 13793-1992 "steel pipes with a longitudinal electric
(resistance) weld". Compared with GB/T 13792-1992 and GB/T 13793-1992, the main
changes are as follows.
-- Directly introduce general standard of welded steel pipe for dimensions;
-- revise permissible deviations of dimension;
-- revise the scope of length along full length;
-- add the classification of steel pipe’s curvature;
-- add the requirements in steel pipe end surface;
-- add the requirements in height of inner weld burr;
-- delete steel designations 08F, 10F and 15F; add steel designation Q235C and
low alloy steel;
-- add post-welding hot-working manufacturing method;
-- revise the spacing of slabs in flattening test;
-- revise the requirements in steel pipe hydraulic test;
-- add the requirements in steel pipe coating; propose the technical requirements in
galvanized pipe;
-- revise inspection and group-batching rules of steel pipe.
Annex A and Annex B of this Standard are normative.
This Standard was proposed by China Iron and steel Association.
This Standard shall be under the jurisdiction of National Iron and steel Standardization
Committee.

Steel pipes with a Longitudinal Electric
(Resistance) Weld
1 Scope
This Standard specifies classification, code name, dimension, shape, weight, technical
requirement, test method, inspection rules, packaging, marking and quality certificate
of steel pipe with a longitudinal electric (resistance) weld.
This Standard is applicable to steel pipe with a longitudinal electric (high frequency
resistance) weld for common purpose of which the outer-diameter is not larger than
630 mm.
