Product Description

API Grade D H 7/8" 1 1/4"  Sucker Rod
API 11B Sucker Rod Polished Sucker Rod and Pony Rod

 

Product Description

 

Product Description
 

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.
