Title
Recommended Practice on Thread Compounds for Casing, Tubing, and Line Pipe

American Petroleum Institute

Publication Date:
Jul 1, 2003

Scope:

This International Standard provides requirements, recommendations and methods for the manufacture, testing and selection of thread compounds for use on ISO/API round thread, buttress thread and proprietary casing, tubing and line pipe connections. The tests outlined within this International Standard are used to evaluate the critical performance properties, and physical and chemical characteristics of thread compounds under laboratory conditions.

These test methods are primarily intended for thread compounds formulated with a lubricating base grease. It is recognized that there may be materials used for the lubrication and/or sealing of threaded connections for which these test methods are not applicable.

This International Standard is not intended for the evaluation of compounds used with rotary shouldered connections. Such evaluation is described in API RP 7A1.

This International Standard does not address the environmental issues associated with the use and disposal of thread compounds.
