What is a Sucker Rod Coupling
The sucker rod coupling is a coupling used to connect two sucker rods. Both ends of the sucker rod coupling are threaded, and sucker rods of different diameters can be combined as required. The couplings produced by our company include sucker rod couplings and reducing couplings, which are designed in accordance with API Spec 11B and made of high-quality carbon steel or alloy structural steel (equivalent to AISI 1045 or AISI 4135). Under normal circumstances, there are two wrench squares on the coupling and the outer circle, but according to user needs, a wrenchless square coupling can also be provided. The hardness of T-class coupling after heat treatment is HRA56-62, which has good corrosion resistance and wear resistance.
In use, sucker rod couplings are used to connect sucker rods of the same size, and reducer couplings are used to connect sucker rods of different sizes or to connect polished rods and sucker rod strings.
