Sinker bar are used between the rod string and oil well pump. Under the action of its weight, the rod string is in a state of tension and keep the rod in the center of the tubing, to avoid sucker rod bending friction tubing in the oil well. Our company can manufacture sinker bar according to API Spec11 B.

Sinker Bar is made of fine carbon steel or alloy steel. It's threads may be either sucker rod pin- thread or polished rod pin-thread. Both ends have the wrench and one end has elevator neck.

When used, sinker bar can be connected with the polished rod at the top of the well, can also be connected with the sucker rod of the underneath of the well.

 

Pony rods are manufactured to the same chemical properties, rod diameters, dimensions and tolerances of our sucker rods. Standard lengths include 2' (0.61 m), 4' (1.22 m), 6' (1.83 m) and 8' (2.44 m). Other lengths are available as a special order.
