Sucker Rod Coupling Centralizer is a kind of modified coupling, which is used to avoid the abrasion between coupling and tubing, so that a long working life.

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

Steel sucker rod is the major equipment for oilfield. We provide grade C, D, K, KD, HL, HS and special alloy sucker rod which are made according to API Spec 11B. Grade C sucker rod is made of fine carbon-steel, featured by moderate strength, good plasticity and better corrosion-resistance. Grade C sucker rod is suitable for sour medium environment where they are not susceptible to sulphuric stress cracking.

Drive Rods for Progressing Cavity Pump applications are available in 1” (25.40mm), 1 1/4” (31.75mm) and 1 1/2” (38.10mm) body diameter and in 25’ (7.62m) lengths.
