Exceptional tensile strength exceeding 1,000 MPa (145,000 psi) ensures reliable performance in demanding oilfield applications. The optimal surface finishing provides proper sealing in stuffing boxes, while the corrosion-resistant properties extend operational lifespan in challenging environments.
Sucker rods are steel rods threaded at both ends, used to connect surface and downhole components of reciprocating piston pumps in oil wells. They serve as the critical link between the pump jack (surface drive) and the downhole pump at the well bottom.
