API RP 7A1

Abstract

This recommended practice is under the jurisdiction of the API Committee on Standardization of Drilling and Servicing Equipment. <br>This recommended practice provides recommendations for testing the frictional performance of thread compounds for rotary shouldered connections. For additional information regarding development of this recommended practice, refer to IADC/SPE 23844¹. All manufacturers, users and others conducting rotary shouldered connection thread compound tests in accordance with this recommended practice are encouraged to submit suggested revisions to the Director of the Production Department, American Petroleum Institute, 1201 Main Street, Suite 2535, Dallas, Texas 76202-3904. <br>Paragraphs 4.1 and 4.2 include provisions whereby a manufacturer may state on the compound label that the manufacturer's compound conforms to API Recommended Practice 7A1. One of the conditions for this is that the manufacturer shall retain the laboratory test results for review on request. API does not evaluate or validate such test reports. API does not in any way approve or make any representation or warranty with regard to a particular compound, its test results, or facilities used for such tests. <br>Conversions of U.S. customary values to International System (SI) metric units are provided throughout the text of this recommended practice in parenthesis, e.g., 6 inch (152.4 mm). <br>¹ E.
