Sucker rods are designed for transmission of translational or rotational motion from ground drive to the well sucker for oil extraction. The rods are round cross-section metal bars ending 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) display enhanced strength and anticorrosion properties, and are highly competitive in terms of quality with the products of world famous companies.
