Threading and Gauging of Rotary Shouldered Connections
Also Known As:
1.1 CoverageThis standard specifies the following requirements on rotary shouldered connections for use in petroleumand natural gas industries: dimensional requirements on threads and thread gauges, stipulations on gaugingpractice and gauge specifications, as well as instruments and methods for inspection of thread connections.These connections are intended primarily for use in drill-string components.
Other supplementary specifications can be agreed between interested parties for special tolerancerequirements, qualification, testing, inspection, and finishing. This standard applies both to newlymanufactured connections and connections that are recut after service. It should be realized that recutconnections are subject to additional inspection and testing—the user is referred to API 7G-2 for suchinformation.
This standard is applicable to preferred rotary shouldered connection designs. These are traceable to aninternationally supported system of gauges and calibration that can be described as number (NC) style,regular (REG) style, or full-hole (FH) style.
