Name:sucker rod couplings

Product Description


1.Class T and Class SM coupling for sucker rods are manufactured as per API 11B

 

2.Class T coupling is using AISI 5140 to manufacture.

 

3.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.

 

4.Also, combination couplings are available for different diameters (sub-coupling) for both Class T and Class SM couplings.Sucker rod coupling is one of our flagship products.

 

5.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.
