API11B Sucker Rod Coupling SM

Haige offers Class T Sucker Rod Couplings and SM Sucker Rod Couplings.Class T and Class SM coupling for sucker rods are manufactured as per API Specification 11B. For the thread cutting, we are using cold form rolled by displacing rather than by removing of material for making the coupling thread. The thread rolling cutting results in a compressive stress at the root of the thread, giving maximum strength to the traditional weak point of cut-thread couplings.
