Product Description
API 11B Sucker Rod Product Overview
Zhongshi Group sucker rods are engineered for transmitting translational or rotational motion from ground drive systems to well pumps for efficient oil extraction. These round cross-section bars feature upset heads and threaded ends for secure connections.
Product Features by Grade
- Grade C: Carbon steel construction with medium strength, excellent plasticity, toughness, and corrosion resistance. Ideal for sour medium environments resistant to sulphuric stress cracking.
- Grade D: Alloy steel with high strength, superior plasticity, and extended service life through heat treatment. Suitable for non-corrosive or light-corrosion oil wells.
- Grade HL & HY: Super-high strength rods with tensile strength reaching 966-1195 MPa. Designed for deep wells or high-capacity pump applications.
- Grade K, KD & KH: Cr-Ni-Mo alloy steel with enhanced anti-corrosion properties. Available for shallow, middle, and deep well applications in corrosive environments.
