API Class T sucker rod couplings
SUCKER ROD COUPLINGS
Sucker rod couplings are a key component in the successful performance of a sucker rod string. By minimizing the wear and corrosion of couplings, the life of the sucker rod string is increased. This can substantially decrease service and repair costs. Our products has set an industry standard with the design of the Premier Performance Sucker Rod couplings including both API Class T (through hard) and API Class SM (spray metal) designs.
For excellent service in mild well environments the API Class T Coupling is the ideal choice. The Class T coupling is manufactured with a through hardiness of between 16 and 23 Rc. This results in high tensile and fatigue strength for the coupling. The outside diameter is smooth to minimize stress concentrations, and an accurate chamfer allows for controlled contact stress. The threads are rolled full form which results in compressive stresses at the thread root and improved fatigue resistance.
