Function Description

Each spare part is designed to solve specific on-site challenges, ensuring reliable performance under the extreme conditions of oilfield operations. Here’s how our key parts address common pain points:

• Rotary Slips Parts: The Die (Slips Inserts 73 mm) 2161 for SDML 3 1/2″ Rotary Slips provides a secure grip on 73 mm drill pipe, with a load-bearing capacity of 400kN, preventing drill pipe slippage that can cause equipment damage and downtime.

• Hydraulic Motors & Wrenches: The 8Y-1000 HYDRAULIC MOTOR delivers a stable torque of 1000 N·m, solving motor stalling and torque fluctuations in drilling operations; the SSW-40 Pneumatic Spinning Wrench provides quick pipe make-up/break-out, reducing operation time by 40 minutes per connection.

• Well Control Components: The DownIBOP assembly 114706-502 ensures quick shutoff in well control emergencies, with a response time of 0.7 seconds, solving valve jamming that endangers well safety; the HYD IBOP ACTUATOR 125594 provides reliable hydraulic force, with a working pressure of 35MPa, preventing actuator failure.

• Filters & Seals: The H11-1003-010 Low pressure filter for Canrig removes 99.9% of contaminants larger than 10μm, preventing system clogging and extending equipment service life by 15 months; the sealing ring 5300102008 has a leakage rate of less than 1ml/h, solving fluid leakage in hydraulic systems.

Structural Features

Our spare parts are built with high-quality materials and precision manufacturing, designed to withstand the harshest oilfield environments—from extreme temperatures to high pressure, salt spray, and dust—while being easy to install and maintain. Key structural features include:

• Durable Material Selection: Critical components like Die (Slips Inserts 73 mm) 2161, 8Y-1000 HYDRAULIC MOTOR, and DownIBOP assembly 114706-502 are made of 42CrMo alloy steel (HRC 52-56), ensuring wear and impact resistance; seals (5300102008, O-RING S01-1459-01N) use nitrile rubber and Turcon materials, resisting crude oil, seawater, and chemical corrosion.

• Precision Machining: All parts are processed by CNC precision machine tools with a machining accuracy of ±0.002mm, ensuring perfect fit with original equipment. Threaded components (30115757 hex screw, PIN CLEVIS 102.24.17) meet 6H precision standards, preventing connection failure and leakage.

• Extreme Environment Adaptability: The ENCODER,DIGITAL LOW TEMP 30122725-HE operates reliably at -50℃ to 80℃, solving encoder failure in frozen oilfields; the SHAFER RUBBER 136791 resists salt spray and high humidity, suitable for offshore operations.

• Easy Installation & Maintenance: Optimized for on-site efficiency— the w18-09-000 shim is pre-cut to 1/16″ thickness, requiring no on-site trimming; the suction filter 5400200008 has a quick-release design, reducing replacement time by 50% for busy on-site teams.

Applicable Working Conditions

Our spare parts are engineered to perform reliably in the most challenging oilfield environments, solving the problem of poor adaptability that plagues ordinary parts:

• Onshore & Offshore Drilling: Resistant to high humidity, salt spray, and corrosive media— the DownIBOP assembly 114706-502 and SHAFER RUBBER 136791 maintain performance in offshore environments, preventing corrosion and leakage.

• High-Pressure Well Control Scenarios: Suitable for wells with working pressure up to 35MPa (5,000psi), such as the HYD IBOP ACTUATOR 125594 and Hydraulic Valve 30173386, ensuring safe well control even in high-pressure conditions.

• Low-Temperature Frozen Oilfields: Adapt to temperatures as low as -50℃— the ENCODER 30122725-HE and 8Y-1000 HYDRAULIC MOTOR start without jamming, ensuring stable operation in cold regions like Daqing Oilfield.

• High-Dust & High-Impact Sites: Desert and open-pit oilfields benefit from the H11-1003-010 Low pressure filter and Rubber Bumper QF36001-04.10, which prevent dust intrusion and protect equipment from impact, reducing wear and failure.

Maintenance and Care Suggestions

Based on decades of hands-on on-site experience, our engineers share practical maintenance tips to extend part life, reduce costs, and avoid common mistakes—these are real-world insights from professionals who’ve worked directly in the field:

• Rotary Slips Parts: Inspect the Die (Slips Inserts 73 mm) 2161 every 3 months for wear; replace if the wear exceeds 0.6mm. Clean the slips inserts after each use to remove drill pipe debris—debris buildup causes uneven wear and drill pipe slippage. Avoid using damaged inserts, as they can scratch or damage drill pipe.

• Hydraulic Motors & Actuators: Check the 8Y-1000 HYDRAULIC MOTOR for oil leaks monthly; add hydraulic oil (ISO VG 46) if the level is low. Lubricate the HYD IBOP ACTUATOR 125594 every 4 months with lithium-based grease—under-lubrication causes actuator jamming and premature failure.

• Filters & Seals: Replace the H11-1003-010 Low pressure filter every 6 months; check the suction filter 5400200008 weekly for clogging. Replace the sealing ring 5300102008 every 18 months—store spare seals in a cool, dry place to prevent aging.

• Fasteners & Connectors: Tighten the 30115757 hex screw with a torque wrench (25-30 N·m) to prevent over-tightening, which strips threads. Inspect the Power connector red 114869-PB-RED monthly for loose connections—loose connectors cause electrical failures in drilling systems.
