2 Normative references

The following documents are indispensable for the application of this document. For dated reference documents, only the dated version applies to this document. For undated references, the latest version (including all amendments) applies to this document. API SPEC 5CT.2018 Specification for casing and tubing (Specification for casing and tubing) NACE TM0177-2016 The laboratory test of resistance to sulfide stress cracking and stress corrosion cracking of metals in H2S environment (Laboratory testing of metals for resistance to sulfide stress cracking and stress corrosion cracking in H2S environments)

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 according to "BG strength grade characteristic values use performance characteristic letters". 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). Use the characteristic letter S or SS, which means it is applicable In an acidic environment, when the "use performance characteristic letter" of the brand is different but the others are the same, the brand with "SS" means this standard The specified sulfide stress corrosion cracking test loading stress requirement (ie, the minimum SSC threshold value) is higher than that of grades containing "S". Performance characteristics The sign letters are "TS" and "TSS", which means that it is suitable for acidic environments and has higher anti-collapse performance than API SPEC 5CT.2018 standard requirements When the "use performance characteristic letter" of the brand is different but the others are the same, the brand with "TSS" means the vulcanization specified in this standard The loading stress requirement (ie the minimum SSC threshold value) of the physical stress corrosion cracking test is higher than that of the grades containing "TS". 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.
