1 Scope
This Standard specifies the technical delivery conditions of cost-effective tubing and casing for CO2-containing or CO2 + H2S-containing environment for Baoshan Iron and Steel Co., Ltd.
This Standard is applicable to cost-effective seamless tubing and casing (hereinafter referred to as tubing and casing) that is applied under medium or mild CO2-containing corrosive environment or CO2 + H2S-containing compound corrosive environment in oil and gas exploitation in the petroleum and natural gas industry.
In this Standard, steel grades of tubing and casing are. BG80-3Cr, BG90-3Cr, BG95- 3Cr and BG110-3Cr, which are applicable to CO2-containing corrosive environment; BG80S-3Cr, BG90S-3Cr and BG95S-3Cr, which are applicable to CO2 + H2S-
containing compound corrosive environment.
Tubing and casing that are stipulated in this Standard include three product specification levels (PSL1, PSL2 and PSL3).
2 Normative References
The following documents are indispensable to the application of this Standard. In terms of references with a specified date, only versions with a specified date are applicable to this Standard. The latest version (including all the modifications) of references without a specified date is also applicable to this Standard.

Unless it is otherwise stipulated in this Standard, this Standard adopts corresponding stipulations of API SPEC 5CT.2011 standard steel grade provided in Table 1. Generally speaking, delivery shall comply with the requirements of PSL1 steel level in API SPEC 5CT.2011 in Table 1. When it is indicated in the contract that product specification level is PSL2 or PSL3, products can also be delivered in accordance with PSL2 or PSL3 in API SPEC 5CT.2011 in Table 1. However, the demand side and the supply side shall BG90S-3Cr
BG95S-3Cr
T-10-80
a The sampling dimension shall be as large as possible. When it is insufficient to take 1/2 dimension of sample, impact test shall be unnecessary.
b The sampling orientation, the sequence of dimension and the evaluation of test result shall comply with the stipulation in API SPEC 5CT.2011.
7.5 Sulfide Stress Corrosion Cracking Test Requirements
Products manufactured with the designations BG80S-3Cr, BG90S-3Cr and BG95S- 3Cr shall receive sulfide stress corrosion cracking test. This test shall adopt Method A or Method D in NACE TM0177-2016 and Solution B. When Method A is adopted, products shall satisfy the stipulation in Table 5. When Method D is adopted, at least the average value K1SSC of three valid samples and the unit value K1SSC of all the valid samples shall satisfy the stipulation in Table 6.
If the supplier can guarantee that products are qualified in this test, this test shall be unnecessary.
7.6 CO2-containing Anti-Corrosion Performance
When users request, and it shall be indicated in the contract, the supplier shall select appropriate methods to conduct autoclave test to test CO2-containing anti-corrosion performance. The acceptance criteria shall be negotiated by the demand side and the supply side. Appendix A (informative) lists out recommended test conditions. 7.7 CO2 + H2S-containing Anti-Corrosion Performance
When users have requirements towards CO2 + H2S-containing anti-corrosion performance and can provide the practical working conditions, simulated working condition evaluation test can be conducted in accordance with users?€? practical working conditions. This shall be negotiated by the demand side and the supply side and indicated in the contract.
7.8 Special Requirements
In accordance with the demand side?€?s requirements, and the negotiation between the demand side and the supply side, tests on hardenability, surface hardness, hardness variation, grain size or other items can be conducted. The specific requirements shall be stipulated through the negotiation between the demand side and the supply side. Table 5
