Spray Polished Rod

Function of Polish Rod

Polish rod is a kind of special sucker rod connected with sucker rod and beam hanger. It is at the top of sucker rod, need to bear the most strength,so with bigger diameter and higher steel grade than sucker rod, and the surface is very smooth.

We also provide: API AISI 4140 Polished Rod, 3/4" Polished Rod.

Main function:

Combined with packing set in packing box to seal wellhead and prevent oil、gas、water disclosure.

Interim connector between sucker rod and mule head hanger.

Finishing indicator diagram test.

Complete various wellhead operation, such as pump striking, regulating pump setting.
