Sucker Rod

Sucker Rod

Sucker rod is an important part of a sucker rod pumping equipment. Sucker Rod connect with coupling to be a rod string, and up through polished rod connection on the pumping unit or PCP motor, down connection on the pump piston or PCP, its role is to ground the reciprocating movement of the pumping unit horsehead suspension point is passed to the downhole pump or pass the rotation of the PCP motor torque to downhole PCP.

Note: when the yield strength cannot be measured, it should be considered to be processed into standard sample installation drawing
a It is generally made of high quality carbon steel, which can reach the mechanical properties of the table.
b Molybdenum steel (but not limited to this type of steel) is generally used, and the mechanical properties of this table can be achieved through effective heat treatment.
