Product Description
API 11B Oilfield Sucker Rods
Zhongshi Group sucker rods are engineered for efficient transmission of translational or rotational motion from ground drive systems to well pumps in oil extraction operations. These round cross-section bars feature precision upset heads and threaded ends for reliable connections.
Product Grades & Applications
- Grade C: Carbon steel construction with medium strength, excellent plasticity, 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 after heat treatment. Suitable for no-corrosion or light-corrosion oil wells.
- Grade HL & HY: Super-high strength rods with tensile strength reaching 966-1195 MPa. Designed for deep wells and high-capacity pumping 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.
