Full Description

This specification covers requirements on drill-stem members (except drill pipe), including threaded connections, gauging practice, and master gauges therefore.

This specification primarily specifies the minimum design, material, inspection and testing requirements for upper and lower kelly valves. This specification also applies to drill-stem safety valves used with overhead drilling systems. It applies to valves of all sizes with rated working pressures of 5,000 through 15,000 psi (34.5 through 103.4 MPa) applied in normal service conditions (H2S service conditions are addressed as a supplemental requirement). Rated working temperatures are -4?F (-20?C) and above for valve bodies; sealing system components may have other temperature limitations. See more
