3 General

Unless otherwise specified in this standard, this standard adopts the corresponding regulations of API SPEC 5CT.2018 standard steel grade given in Table 1.Generally used The API SPEC 5CT.2018 standard in Table 1 corresponds to the PSL1 grade requirements of the steel grade. When the contract indicates that the product specification level is PSL2 or For PSL3, it can also be supplied according to the PSL2 or PSL3 grade of the corresponding steel grade in the API SPEC 5CT.2018 standard in Table 1, but at this time, it should be supplied by supply and demand. The two parties negotiate and specify the specific requirements of the selected PSL2 or PSL3 level in the contract. 4 Designation methods, terms, definitions, symbols and abbreviations 4.1 Representation of grades The grades (steel grades) of this standard are named after "BG strength grade characteristic values use performance characteristic letters-characteristic elements and content representative values (default)". Among them, "BG" is composed of the first pinyin letter "B" of "bao" in Baosteel Co., Ltd., and the first pinyin letter "G" of "pipe" in pipe. The characteristic value of the strength level is the value that specifies the minimum yield strength (in ksi). The characteristic letter used for performance is H, which means it has high temperature resistance. "-3Cr" means that the representative value of the characteristic element Cr content is 3%. 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.
