Audited Supplier API 11B Sucker Rod with Coupling and rod guide
Sucker rods are designed for transmission of translational or rotational motion from ground drive to the well pump for oil extraction. The rods are round cross-section bars whose ends are provided with upset heads and thread.
The rods can be rigged with various centralizers, to protect rods, couplings, and oil well tubing from wear; rods can be additionally provided with mobile scrapers for removal of paraffin deposits. "D" class sucker rods (as per API specification) display enhanced strength and anticorrosion properties, and are highly competitive in terms of quality with the products of world famous manufacturers.
