Product Description
API 11B Certified Sucker Rods for Oilfield Applications
Our polished sucker rods are manufactured according to API Spec 11B standards, available in multiple grades including D, K, KD, HL, and HY types. These rods are engineered for reliable performance in various oilfield environments.
Product Grades & Applications
- Grade C: Moderate strength, resistant to sulfide stress cracking, suitable for sour medium environments
- Grade D: High tensile and yield strength from quality heat-treated steel alloy, ideal for non-corroding or mildly corroding environments
- Grade K & KD: Excellent corrosion resistance in H2S, CO2 and NaCl media with superior tensile strength
- Grade HL & HY: High strength construction matching grade D dimensions, capable of withstanding 966-1,136 MPa (140,000-164,720 psi) for deep and large displacement wells
- Hollow Sucker Rods: Grade D 1-inch hollow rods available for specialized well drilling and oil gas production
