Product Description

API Polished & Sucker Rod Couplings for Oilfield Rods

Product Description

Sucker Rod Coupling

Couplings are manufactured from quenched and tempered micro alloyed steels. API couplings are furnished in two classes: Class T and Class SM (Spray Metal). The later has a superficial hardening
One sucker rod coupling must be processed by a few fabrication procedures, such as, Blanking, drilling hole, boring hole, milling, thread tapping, and so on. At the last step, do the surface treatment. The surface treatment includes black coating, phosphating or per the customers requirement. Besides, it has good anticorrosion and anti-friction property. The following table shows the related information about the sucker rod coupling

Polished rod coupling
Polished rod couplings are designed for connecting of the polished rod to the top rod of the string. Contrary to rod couplings, polished rod couplings have a female cone that eliminates the coupling twist-off in the course of operation.
