4 Representation Methods of Designations, Terms,
Definitions, Symbols and Abbreviations
4.1 Representation methods of designations
The designations (steel grades) of this Standard are named according to "BG +
characteristic value of strength grade + characteristic letter of use performance ".
Among them, "BG" is composed of the first pinyin letter "B" of "Bao" in Baosteel Co.,
Ltd., and the first pinyin letter "G" of "Guan" in tubes. The characteristic value of the
strength grade is the value that specifies the minimum yield strength (in ksi). The
characteristic letter of use performance U means Upgrade; and S means Super;
corresponding to different alloy content.
4.2 Terms, definitions, symbols and abbreviations
Unless otherwise specified in this Standard, the terms, definitions, symbols and
abbreviations used in this Standard are consistent with those specified in API SPEC
5CT:2018.
