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.
Class T coupling is using AISI 5140 to manufacture.The coupling is
coated using phosphate chemical treatment or black oxide on
customer's request.For Class SM coupling, the spray metal is a
specification hardening process and is applied 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.
