A sucker rod is a steel rod, typically between 25 and 30 feet in length, and threaded at both ends, used in the oil industry to join together the surface and downhole components of a reciprocating piston pump installed in an oil well. The pumpjack is the visible above-ground drive for the well pump, and is connected to the downhole pump at the bottom of the well by a series of interconnected sucker rods.
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.
We provide three kinds of sucker rods: solid sucker rods, hollow sucker rods and special sucker rods for PC pumps. The features are as follows:
The rod connector is welded with the rod body through friction welding followed by heat treatment and rolling depression. The sucker rods have the advantage of stable mechanical property and improved fatigue strength.
The thread is machined using a compression and rolling machine resulting in a continuous metal fiber of the thread. This technique improves thread strength and decreases stress concentration. The center diameter of the thread is controlled strictly, which makes the load to be evenly taken by the thread teeth thus increasing load capacity and preventing loosening of the connection.
The rod body, connector and coupling are made of quality 20CrMo and 35CrMo quenched and tempered alloy steel, which improves overall mechanical properties.High coaxiality between the connector thread and the rod body gives the sucker rod high bending strength.
