The Function and Working Principle of Sucker Rod Coupling

The Function and Working Principle of Sucker Rod Coupling

The sucker rod is a slender rod of the pumping well, the sucker rod is a single length of 7.62 or 8 meters, 9.14m, the material is generally low carbon alloy steel after tempering treatmSucker ent, in the oil pipe with internal thread hoop one by one connected to extend to the underground oil layer of the piston, through the reciprocatSucker Rod Couplinging movement to pump oil.

SVES Oilfield Supply Co., Ltd provide a wide range of high precision and tight connections, including SM class and T class, designed in accordance with APISpec11B specifications and manufactured from high-quality carbon steel and alloy structural steel.

Under normal circumstances, there are two wrench sides on the collar and the outer circle, but according to the needs of the user, no wrench can also be provided.

The hardness of the T-grade coupling after heat treatment is HRA56-62, which has good corrosion resistance and wear resistance.

In use, rod coupling is used to connect rod of the same size and reducer coupling is used to connect rod of different size or to connect sucker rod and sucker rod string.
