Kelly Saver Sub A Kelly Saver Sub is a heavy-duty drilling accessory installed between the Kelly and the drill string swivel or drill pipe to protect the Kelly's threaded connections from excessive wear and damage caused by repeated make-up and break-out operations. By acting as a sacrificial connection, the Kelly Saver Sub extends the service life of the Kelly, reduces maintenance costs, and improves drilling efficiency in rotary drilling operations. Our Kelly Saver Subs are available for sale and lease, providing reliable performance for onshore and offshore drilling contractors, exploration companies, and oilfield service providers. Applications Rotary drilling operations Oil and gas exploration wells Onshore drilling rigs Offshore drilling platforms Water well drilling Geothermal drilling Mining exploration drilling Directional drilling operations Drill string protection Drill pipe connection management Technical Features Manufactured from premium forged alloy steel. Precision-machined API pin and box threaded connections. Heat-treated for superior strength and wear resistance. High torsional strength for demanding drilling conditions. Protects Kelly threads from repeated wear. Corrosion-resistant surface treatment. Suitable for high-torque drilling applications. Excellent fatigue and impact resistance. Compatible with standard rotary drilling systems. Designed for long service life and easy replacement. Available Types Standard Kelly Saver Sub Heavy-Duty Kelly Saver Sub API Regular Kelly Saver Sub API IF Kelly Saver Sub Custom Thread Kelly Saver Sub High-Torque Kelly Saver Sub Sour Service Kelly Saver Sub Typical Specifications Parameter Specification Outside Diameter (OD) 3½" – 8" Length 24" – 60" Connection API REG, IF, FH, NC Series Material High-strength alloy steel Heat Treatment Quenched and Tempered Torque Capacity High-torque drilling applications Standard API Spec 7-1 Service Standard and Sour Service (NACE compliant options) Key Benefits Protects expensive Kelly threads from wear. Extends the service life of the Kelly. Reduces maintenance and replacement costs. Improves drilling efficiency. Provides reliable high-torque performance. Minimises downtime during drilling operations. Enhances drill string reliability. Suitable for harsh drilling environments. Easy to install and replace. Long operational lifespan. Industries Served Oil & Gas Exploration Offshore Drilling Onshore Drilling Geothermal Drilling Water Well Drilling Mining Exploration Energy Service Companies Drilling Contractors Petroleum Engineering Firms National Oil Companies (NOCs) Kelly Saver Sub Sales and Lease We supply new and refurbished Kelly Saver Subs from leading global manufacturers for both sale and short- or long-term lease. Every unit undergoes rigorous dimensional inspection, thread gauging, non-destructive testing (NDT), and quality assurance to ensure compliance with API standards before delivery. Our Sales & Leasing Services Include New and refurbished Kelly Saver Subs. Short-term, long-term, and project-based rental options. API-certified inspection and quality assurance. Thread inspection and recertification. Refurbishment and repair services. Technical consultation for equipment selection. Fast mobilisation for offshore and onshore operations. Worldwide logistics and delivery. Complete documentation, inspection reports, and test certificates. Our Kelly Saver Subs are engineered to provide exceptional durability, thread protection, and dependable performance in demanding drilling environments. Designed to reduce wear on valuable Kelly connections, they help operators lower operating costs, minimise non-productive time (NPT), and improve overall drilling efficiency.
