1/8" API Certified Sucker Rod with Coupling - 5/8" to 1-1/8" Diameter, 620-1195 MPa Tensile Strength
Sucker rods are engineered for transmitting translational or rotational motion from ground drive systems to well pumps during oil extraction operations. These round cross-section bars feature upset heads and threaded ends for secure connections.
- Compatible with various centralizers to protect rods, couplings, and oil well tubing from wear
- Optional mobile scrapers available for paraffin deposit removal
- API "D" class rods offer enhanced strength and superior corrosion resistance
- Competitive quality matching world-renowned manufacturers
- Grade C: Carbon steel construction with medium strength, excellent plasticity, toughness, and corrosion resistance suitable for sour medium environments
- Grade D: Alloy steel with high strength, superior plasticity, and extended service life after heat treatment for non-corrosive or light-corrosion environments
- Grade HL/HY: Super-high strength rods with tensile strength of 966-1195 MPa, ideal for deep wells or high-capacity pump applications
- Grade K/KD/KH: Cr-Ni-Mo alloy steel with powerful anti-corrosion properties for strong corrosion environments
