API11B Sucker Rod with Coupling and Centralizer
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 rods and couplings are manufactured in accordance with API 11B. We can supply sucker rods as follows:
Grade: C, D, K, KD, H;
Size (in,): 5/8 (16 mm), 3/4(19 mm), 7/8 (22 mm) , 1 (25 mm), 1-1/8 (28 mm).
The sucker rods and conventional/slim hole couplings with various sizes are available as well.
We can also provide corrosion resistant sucker rods, FRP (fiber glass reinforced plastic) sucker rods, polished sucker rods and couplings, special sucker rods for progressive cavity pumps, hollow sucker rods and electric heating systems.
