Function Description
Each part in our lineup plays a vital role in keeping your rig and handling tools operational, solving specific pain points you face in the field—many of which align with common fault scenarios outlined in industry maintenance guides: 14-630-180 “CMS-3” Taper Casing Slips provide a secure grip on tapered casing, preventing slippage and misalignment during running—solving the common problem of tapered casing damage that leads to well bore issues. 7624-5104 Rotary Slips grip 16 1/2″–18″ drill pipe tightly, avoiding slippage that damages the drill string and causes downtime. DCS R 2628 Button Inserts restore grip to AOT “DCS” Drill Collar Slips, preventing collar slippage and extending slip service life. SDXL 15562 Rotary Slips (less inserts) offer a durable base for high-torque pipe operations, allowing you to use your existing inserts and reduce costs. T11511 Long Jaw for Type C Tong and T11194-1 Long Jaw Assy for Type B Tong ensure secure pipe gripping during makeup/breakout, eliminating the risk of pipe slippage and worker injury. Hinge pins (7638-B-59, E26813) enable smooth movement of tong and slip components, reducing friction and wear—avoiding the seized or misaligned hinges that cause equipment jams. 34-632 Hydraulic Cylinder Assy ensures leak-free hydraulic flow, preventing hydraulic system failures that shut down rig operations. Every part works together to create a reliable, low-maintenance system that keeps your rig running.
Structural Characteristics
Our parts are built to withstand the harshest oilfield conditions, with structural features that address real-world wear and tear—incorporating lessons from industry fault data: All metal components (including 14-630-180 Taper Casing Slips and 7624-5104 Rotary Slips) are heat-treated to a hardness of 44-48 HRC, making them resistant to bending, wear, and impact—solving the problem of premature part failure. Our DCS R 2628 Button Inserts feature a reinforced button design that distributes load evenly, preventing insert wear and extending service life—addressing the root cause of insert failure in high-torque operations. Inserts (34-230, 7613-H-81) use a proprietary rubber compound that offers 34% better grip than standard inserts, even in high-pressure, high-mud environments—avoiding slip slippage. Hinge pins (7638-B-59, E26813) are zinc-plated and coated with a corrosion-resistant layer, ensuring durability in offshore saltwater environments. The modular design of all our parts makes installation quick and easy; most components (like E29337 Link Block or E34909 Latch Spring) can be replaced in under 15 minutes by a single technician, reducing labor costs and downtime. We also incorporate robust link block nuts (E939484-7) and lockwashers (E939352-64) to prevent component loosening, a common cause of tong and slip failure in high-vibration environments.
Applicable Working Conditions
Our spare parts are engineered to perform in the most challenging oilfield environments, including: onshore deep wells (temperatures up to 235°F, pressures up to 18,500 psi), offshore semi-submersible rigs (saltwater corrosion, high winds, and constant vibration), shale gas drilling sites (continuous high-torque operations), and acidic gas fields (H2S exposure). They are compatible with Type B/C tongs, AOT “DCS” Drill Collar Slips, DU Rotary Type Slips, TS-100 Slips, DCSL 2525/DCSR 2520 Drill Collars, ZJ series rigs (ZJ 30-ZJ 70), and HT series tongs (HT-65, HT-100). Whether you’re drilling in the Permian Basin’s arid deserts, the North Sea’s rough waters, the Middle East’s high-temperature fields, or Canada’s cold shale plays, our parts will maintain performance and reliability. Our 7624-5103 Rotary Slips handle 10 1/2″–11 5/8″ drill pipe, making them ideal for medium-depth wells, while our 34-632 Hydraulic Cylinder Assy works seamlessly with hydraulic systems in both onshore and offshore rigs—aligning with the diverse needs of modern drilling operations.
Maintenance & Care Recommendations
To maximize the service life of our parts and avoid costly mistakes, our senior oilfield engineers (with 33+ years of on-site experience, including expertise in fault排查) recommend these practical tips: Inspect 14-630-180 “CMS-3” Taper Casing Slips every 180 drilling hours for signs of wear or deformation—replace if the slip segments show cracks or uneven wear (a common mistake that leads to tapered casing slippage). Clean slip inserts (34-230, 7613-H-81) after each use with a non-abrasive cleaner to remove drilling mud and debris, which can reduce grip and cause premature wear—following the top priority of field maintenance: keeping slip surfaces clean. Lubricate hinge pins (7638-B-59, E26813) and link blocks (E29337) with high-temperature, corrosion-resistant grease every 120 hours to prevent friction and seizing—avoid using generic grease, which breaks down in high temperatures and causes component failure. Store SDXL 15562 Rotary Slips in a dry, clean area when not in use to prevent corrosion of the metal frame. For offshore applications, apply a corrosion-resistant coating to all metal parts every 3 months to protect against saltwater damage. Never reuse E939672-18 Cotter Pins—they are designed for one-time use, and reusing them can lead to breakage and equipment failure, a common oversight in field maintenance that costs rigs thousands in downtime.
