 SANMON can supply sucker rods,polished rods and sinker bars.

Sucker rod is the common equipment in the oil extraction. It is manufactured through many process including the testing, straightening and forging. The sucker rod is placed between the polished rod and oil well pump. To deliver power. Sucker rod is manufactured from high quality carbon steel and alloy steel, which is conform to the API Spec 11B standard.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 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 horse head suspension point is passed to the down-hole pump or pass the rotation of the PCP motor torque to down-hole PCP.
