Description

Pumping rods (of normal length, shortened) and their couplings are elements of the equipment of a rod well pumping unit for oil production. They are made of alloyed steel grades in accordance with customer requirements.
According to the technical specifications, the products meet the requirements for products of a high quality category in accordance with international standards.
The rod couplings are manufactured according to the Customer's requirements.
At the request of the Customer, the rods are equipped with centralizers mounted on the body of the rod: fixed centralizer scrapers, floating scrapers, CVN centralizers and inter—shaft centralizers. The above products are made of high-strength glass-filled polyamide at a comprehensive injection molding machine.
Designed to transfer translational or rotational motion from an onshore drive to a downhole pump during oil production.
