Product Description

Product Description

    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.

Ordinary sucker rod is manufactured according to API Spec 11B which mainly includes grade C and D. Grade H sucker rod is developed to suit for deep well and larger pumps.

Sucker rod: A string or solid or hollow tubular that is moved by a pump jack at the surface to operate a rod pump at the bottom of the well.

Pony rod: A short rod for spacing out a rod string.

Anti-corrosion sucker rod:The material used for the nickel based alloy spray welding, the spray welding layer is larger than 0.25mm so that the ends has antiseptic performance and mechanical protection. In the process of oil sucking rod in rod elevator, can avoid the anticorrosion layer damage. The tooth tongs used in the process of assembly is preventing damage of the wrench side anticorrosion layer.
