Foreword
This Standard is drafted in accordance with the requirements and format of GB/T 1.1-
2009 Directives for Standardization - Part 1. Structure and Drafting of Standards.
This Standard is drafted in accordance with the characteristics of products and
techniques of this enterprise.
Please be noted that certain content in this Standard might involve patents. The issuing
institution of this Standard does not undertake the responsibility of identifying these
patents.
This Standard serves as a replacement of Q/BQB 263-2014. In comparison with
Q/BQB 263-2014, there are several main changes as follows.
---The content of standard notification (2017-202) is included. the requirement of
carbon content of the chemical composition (smelting analysis and finished
product analysis) of designations BG80-3Cr, BG90-3Cr, BG95-3Cr and BG110-
3Cr in Table 2 is modified from ≤ 0.30% into ≤ 0.35%;
---Normative references adopt API SPEC 5CT.2011; NACE TM0177 adopts the
newest Version 2016;
---In the designation part, the implemented standard is modified from “Q/BQB 263-
2014” into “Q/BQB 263-2018”.
Appendix A in this Standard is informative.
This Standard was proposed by the Manufacturing Management Department of

The release of previous versions of the standard replaced by this Standard is as follows.
---Q/BQB 263-2010, Q/BQB 263-2014.
Cost-effective Tubing and Casing for CO2-containing
or CO2 and H2S-containing Environment
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.
API SPEC 5CT.2011. Specification for Casing and Tubing
NACE TM0177-2016. Laboratory Testing of Metals for Resistance to Sulfide
Stress Cracking and Stress Corrosion Cracking in H2S Environments
3 General Rules
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.
