Product Description
Zhongshi provides API 11B sucker rods in various grades (D, K, H) manufactured from high-quality alloy steel or customized to client specifications. Our production process utilizes advanced equipment and rigorous quality control, with all rods undergoing professional performance testing and evaluation before delivery.
Product Grades & Applications
- Grade C: Moderate strength, resistant to sulfide stress cracking, suitable for sour medium applications
- Grade D: High tensile and yield strength from heat-treated steel alloy, ideal for non-corroding or mildly corrosive environments
- Grade K: Excellent corrosion resistance in H2S, CO2, and NaCl media with superior tensile strength
- Grade HL/HY: High strength design matching Grade D dimensions, withstands 966-1,136 MPa (140,000-164,720 psi), suitable for deep and large displacement wells
We also provide comprehensive rod accessories including polish rods, sinker bars, rod couplings, and pony rods. API Type T or spray metal couplings are available in pin sizes from 5/8" through 1 1/8" in full size or slim-hole diameters, with sub couplings for connecting polished rods or tapered rod strings.
