Sucker rod couplings, polished rod couplings and sub-couplings are engineered and designed to meet the challenges existing in today's rod-pumped applications. They are available in API Class T or SM, and in all Sucker rod sizes. Couplings are manufactured from special quality cold-formed steel extrusions or cold drawn seamless mechanical steel tubing. Sucker rod couplings, polished rod couplings and sub-couplings are available in full size, slimhole or oversize outside diameters with effective-width Enhanced Contact Face (ECF) designs.
The main types of sucker rod couplings are sucker rod couplings, polished rod couplings and sub-couplings.
All the three types have two classes: class T and class SM.
The outer diameter of the sucker rod couplings has a full size and slim hole types…
