Product Description

Sucker Rod Introduction:

A "sucker rod" is a long, slender, and flexible rod used in the oil and gas industry to transmit power from a surface pumping unit to downhole pumping equipment such as a pumpjack. Sucker rods are typically made of high-strength steel and are connected in a series to create a rod string that extends down into the wellbore. These rods are essential for transferring the reciprocating motion from the surface to downhole pumps, allowing for the extraction of oil or other fluids from the well.
All sizes of sucker rod (standard, heavy, polish rod) which conform to API specification latest version 11B are available in grade K, C, D and HL.
