API Class T sucker rod couplings for oil drilling equipment
Sucker rod couplings are used to connect sucker rod. It is very important for the performance of sucker rod.
We can produce API SM sucker rod couplings and API T sucker rod couplings.
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.
