Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 23512-2009 "Oil and Gas Industry casing, tubing and line pipe thread compound", and
GB/T 23512-2009 compared, in addition to editorial changes, the major technical changes are as follows.
--- Modify the standard name;
--- Increased consistency;
--- Modify the terms and definitions;
--- Increased APIRP7A1 "rotary shouldered threaded joints fat test" content.
This standard uses the translation method identical with ISO 13678.2010 "oil and gas industry --- casing, tubing, line pipe and drill string member
Threaded fat. "
And this standard Normative international document correspondence between consistency of the following documents.
--- GB/T 269-1991 grease and petroleum grease cone penetration assay (eqv ISO 2137. 1985);
--- GB/T 4929-1985 Determination of dropping point grease (eqv ISO 2176. 1979);
--- GB/T 7326-1987 grease copper corrosion test (eqv ASTMD4048. 1981).
Please note that some of the content of this document may involve patents. Release mechanism of the present document does not assume responsibility for the identification of these patents.

Oil and gas industry casing, tubing,
Line pipe and drill string member threaded grease Evaluation and testing
1 Scope
This standard specifies requirements for a threaded sleeve, tubing, line pipe and rotary shouldered threaded connection fat, inspection and test methods.
This standard specifies the test is used to evaluate the thread compound under laboratory conditions using the properties and physical and chemical properties.
The standard test method is applicable to screw grease grease formulations, does not apply to other thread grease formulations. Or the site of many areas
This type of thread compounds have environmental protection requirements, but are not included in this standard to meet the requirements of environmental protection. The end user is responsible for investigating
These requirements and accordingly make a choice, use and disposal of waste thread compound and related decisions.
2 Conformance
Dual 2.1 Normative references cited documents
Normative references listed in Chapter 3, and the contents of its requirements (API), American Society for Testing and Materials American Petroleum Institute
(ASTM) relevant documents and American National Standards Institute (ANSI) to develop interchangeable. These files behind ISO file,
"Or" connection, such as "ISO ×××× or API ××××". This way replace the files listed using the previous ISO file
Member may lead to different results. However, both the result is acceptable, so in actual use of these documents is considered to be mutually
Exchanged.
2.2 units of measurement
In this standard, data is presented in the International System of Units (SI) and USC units (USC) units of two systems. For a particular
Order approved, except as otherwise provided, should only be used in one system represents the data can not be useful combinations of data expressed in other units.
Regulate the production of these products according to any one of the units represented by the units should be considered equivalent and interchangeable. Therefore, in line with
Expressed in one system of the requirements of this product must also comply with the requirements in another unit system representation.
In the SI system of units, comma represents the decimal separator and a space represents thousands separator. In USC units, the small dots (Online
A) represents the decimal separator and a space represents thousands separator. In this standard, the brackets are expressed in SI units after the USC
Data units indicated.
