Product Q&A
Q:What standards do the couplings meet?
A:
Class T and Class SM couplings are manufactured in strict accordance with API Specification 11B.
Q:What is the difference between Class T and Class SM?
A:
Class T uses AISI 5140 steel, while Class SM features a spray metal coating hardening process applied to the base metal.
Q:Are the threads cut or rolled?
A:
Threads are cold form rolled by displacing material, which creates compressive stress for higher strength compared to cut threads.
Q:What surface treatments are available?
A:
Customers can request phosphate chemical treatment, black oxide, or spray metal coating depending on the coupling class.
Q:What is the recommended maintenance for couplings?
A:
We recommend changing sucker rod couplings after three make-ups, provided the threads are inspected and deemed acceptable.
