API Approval sucker rod couplings-used in oil well drilling

API Class T 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, it increases the life of sucker rod.

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.
