Sucker Rod Coupling
Introduction
Class T and Class SM coupling for sucker rods are manufactured as per API 11B Class T coupling is using AISI 5140 to manufacture. AS for Class SM coupling, the spray metal is a specified hardening process which is used on the base metal. The couplings are available in full size, slim hole and over size. Also, combination couplings are available for different diameters (sub-coupling) for both Class T and Class SM couplings
