Foreword
This document was drafted in accordance with the provisions of GB/T 1.1-2020
“Directives for standardization - Part 1: Rules for the structure and drafting of
standardizing documents”.
This document integrates and revises GB/T 17395-2008 “Dimensions, shapes, masses
and tolerances of seamless steel tubes” and GB/T 21835-2008 “Dimensions and masses
per unit length of welded steel pipes”.
Compared with GB/T 17395-2008 “Dimensions, shapes, masses and tolerances of
seamless steel tubes”, in addition to structural adjustments and editorial changes, this
document has the following major technical changes:
a) MODIFY the outer diameter and wall thickness specification table of common
steel tubes, and EXPAND the outer diameter and wall thickness specification
range (see Table 1 and Table 2 of this document, Table 1 of GB/T 17395-2008);
b) DELETE the outer diameter series of precision steel tubes (see Table 3 of this
document, Table 2 of the 2008 edition);
c) MODIFY the outer diameter and wall thickness specification table of precision
steel tubes, and EXPAND the outer diameter and wall thickness specification
range (see Table 3 of this document, Table 2 of GB/T 17395-2008);
d) MODIFY the outer diameter and wall thickness specification table of stainless
steel tubes, and EXPAND the outer diameter and wall thickness specification
range (see Table 4 of this document, Table 3 of GB/T 17395-2008);
e) ADD the inner diameter tolerances (see 4.3.3 of this document);
f) ADD the minimum wall thickness tolerances (see 4.3.5 of this document).
Compared with GB/T 21835-2008 “Dimensions and masses per unit length of welded
steel pipes”, in addition to structural adjustments and editorial changes, this document
has the following major technical changes:
a) MODIFY the wall thickness series of common steel tubes (see Table 1 and Table
2 of this document, Table 1 of GB/T 21835-2008);
b) MODIFY the outer diameter and wall thickness specification table of common
steel tubes, and EXPAND the outer diameter and wall thickness specification
range (see Table 1 and Table 2 of this document, Table 1 of GB/T 21835-2008);
c) DELETE the outer diameter series of precision steel tubes (see Table 3 of this
document, Table 2 of the 2008 edition);
Dimensions, shapes, masses and tolerances of steel tubes
1 Scope
This document specifies the dimensions, shapes, masses and tolerances of steel tubes.
This document applies to the selection of dimension, shape, mass and tolerance when
formulating standards for circular steel tubes for various purposes.
2 Normative references
The following referenced documents are indispensable for the application of this
document. For dated references, only the edition cited applies. For undated references,
the latest edition of the referenced document (including any amendments) applies.
GB/T 30062 Terminology of steel pipes and tubes
3 Terms and definitions
For the purpose of this document, the terms and definitions defined in GB/T 30062
apply.
4 Dimension specifications
4.1 Outer diameter series
Except for the nominal outer diameter (D) of precision steel tubes, the nominal outer
diameters of other steel tubes are divided into three series: Series 1, Series 2 and Series
3. Series 1 is a general series and is recommended; Series 2 is a non-general series;
Series 3 is a few special and dedicated series.
4.2 Outer diameter and wall thickness
The nominal outer diameter and nominal wall thickness (S) of common steel tubes are
shown in Table 1 (S ≤ 65 mm) and Table 2 (S > 65 mm); the nominal outer diameter
and nominal wall thickness of precision steel tubes are shown in Table 3; the nominal
outer diameter and nominal wall thickness of stainless steel tubes are shown in Table 4.
