Detailed Product Description & Technical Parameters

1. Product Introduction

This comprehensive spare parts collection covers 35×35/35×70 BOP cylinder heads, gate rubber cores, shear knives, and locking shafts, ZQ203 power tong ears, bearing covers, and brake shoes, ZJ series rig sprockets, oil slingers, and brake belts, DQ70 top drive jaw holders and filter elements, hydraulic tank gaskets and clamps, electric control console accessories, and diesel engine filters, sensors, and seals, with unique model identifiers (0306-01M, JK00213-3L, JK212-40S-6-3, etc.) for quick identification and targeted procurement. Raw materials are selected for extreme oilfield resilience: forged alloy steel for load-bearing parts, high-temperature fluororubber for seals, hardened steel for wear components, and corrosion-resistant metals for hydraulic and BOP parts. Each part undergoes strict pressure testing, dimensional inspection, and wear testing before shipment to guarantee consistent performance and reliability.

2. Core Function Description

• BOP Well Control & Sealing: 35×35/35×70 BOP cylinder heads, gate rubber cores, and shear rams provide zero-leak pressure containment up to 105MPa, preventing blowouts and ensuring strict well control safety compliance; locking shafts and connecting bolts secure BOP components for stable operation.

• Drill Pipe Handling Stability: ZQ203-100/ZQ203-125 power tong ears, jaw plate rollers, and brake shoes enable secure, precise gripping and rotation of drill pipes; pneumatic components and adjusting screws ensure smooth tong operation, reducing pipe damage and handling hazards.

• Rig Power Transmission & Braking: ZJ series rig sprockets, oil slingers, and clutch hubs ensure smooth torque transfer for winch and turntable operation; brake belts and disc brake components deliver reliable, precise braking control to avoid operational accidents.

• Hydraulic & Diesel System Efficiency: F-series hydraulic tank gaskets, flanges, and safety valves maintain clean fluid flow and stable system pressure; diesel engine filters, sensors, and oil seals prevent fluid leaks and optimize combustion efficiency.

• Electric Control & Top Drive Performance: FKQ640/FKDQ640 control box accessories and proximity switches ensure stable operation of rig electric systems; DQ70 top drive components optimize drilling efficiency and pipe handling accuracy.

3. Structural & Material Features

• Ultra-Precision CNC Machining: All structural parts feature ±0.01mm dimensional tolerance, ensuring 100% OEM fit without modification or adjustment during on-site installation.

• Reinforced Multi-Layer Sealing: BOP rubber cores and hydraulic seals adopt a labyrinth design, effectively blocking dust, mud, and high-pressure fluid leakage in harsh field environments.

• High-Strength Wear Resistance: Load-bearing components use hardened alloy steel (58-64 HRC hardness); sealing parts use heat-resistant fluororubber that resists aging and cracking at extreme temperatures.

• Modular Quick-Change Design: Wear-prone parts (BOP seals, power tong brake shoes, rig sprockets) use a modular structure, reducing on-site repair time by 75% compared to traditional integrated parts.

4. Applicable Operating Conditions

These spare parts are engineered for onshore deep well drilling, offshore platform workover, desert oilfield operations, high-pressure well control, and rig emergency maintenance, with full adaptability to the following conditions:

• Pressure Range: 0-105MPa (BOP & high-pressure hydraulic systems) / 0-35MPa (rig winch & brake systems)

• Temperature Range: -45°C to 260°C (sealing components) / -35°C to 225°C (mechanical structural parts)

• Environmental Types: Offshore saltwater platforms, arid desert drilling sites, cold-region oilfields, high-temperature deep well operations

• Application Scenarios: Routine rig maintenance, emergency fault repair, equipment refurbishment, well control operations, drill pipe/casing handling

5. Maintenance & Upkeep Recommendations

• Regular Inspection Cycle: Inspect BOP sealing components, power tong wear parts, and rig winch shafts every 550 operating hours; check for wear, cracks, or leakage, and replace damaged parts immediately to avoid safety hazards.

• Lubrication Protocol: Lubricate rig sprockets, shafts, and clutch components with high-temperature lithium grease every 380 hours; replace hydraulic tank filters and diesel fuel filters every 1600 hours to prevent fluid contamination.

• Storage Requirements: Store spare parts in a dry, dust-free environment with relative humidity ≤55%; seal rubber seals and precision components in anti-oxidation packaging to prevent premature aging.

• Installation Standards: Follow API rig maintenance specifications for torque tightening (BOP bolts, engine fasteners); use specialized tools for seal installation to avoid damage and ensure proper seating.

• Performance Monitoring: Track hydraulic system pressure, diesel engine temperature, and top drive operation; adjust valves and replace worn components if fluctuations or abnormalities occur.

On-Site Fault Repair Cases (Field-Verified Solutions)

Case 1: FZ35-70 BOP Left Cylinder Head Failure Repair

An offshore drilling platform experienced BOP pressure loss and sealing failure due to a cracked left cylinder head (JK00213-3L) on the FZ35-70 BOP, halting well control operations. Replacing the damaged cylinder head with our precision-forged component restored pressure integrity, eliminated leakage, and the BOP passed 105MPa pressure testing on the first attempt, resuming operations within 2 hours.

Case 2: ZQ203-100 Power Tong Brake Shoe Wear Fix

A land drilling rig in the Middle East reported unstable drill pipe rotation and slippage due to worn brake shoes (E010101-00M) on the ZQ203-100 power tong, causing operational delays. Installing our high-friction, wear-resistant brake shoes restored braking control, eliminated slippage, and extended brake shoe service life by 70% compared to standard parts.

Case 3: ZJ32L6 Winch Brake Belt Breakdown Resolution

A ZJ32L6 drilling rig suffered complete winch braking failure due to a frayed brake belt, posing serious safety risks. Replacing the worn brake belt with our heavy-duty, heat-resistant model restored reliable braking function, and the rig operated safely for 12+ months of continuous use with no recurring issues.
