Product Description

API 11B Grade C D K KD Sucker Rod for Oil production
 

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.
