Functional Specifications

• MAN Heavy Truck Parts: Covers transmission, cooling, fuel, brake, and clutch systems for MAN33.373DFC/430TGA models, resolving seal leaks, filter blockages, belt tension issues, and clutch component wear to maintain truck hauling efficiency and safety

• Logging & Inclinometer Accessories: Delivers sealing, connection, and centering components for MAXIS-500 logging tools and ZT-MWD650/HT-MWD.X15 inclinometers, ensuring stable data transmission, pressure resistance, and downhole tool alignment

• Drill Pipe Power Tong Components: Provides jaws, hydraulic hoses, fasteners, and rollers for ZQ203-100/125 tongs, supporting high-torque drill pipe handling and preventing slippage or equipment damage during drilling operations

• Drilling Rig Accessories: Includes flush tubes, oil seals, and packing assemblies for XJ/SL/ZJ rigs, maintaining hydraulic system integrity and preventing fluid leakage in continuous drilling operations

Structural & Material Advantages

• High-Grade Material Construction: Wear-resistant alloy steel for drill tong jaws, heat-resistant nitrile rubber for oil seals, corrosion-resistant stainless steel for logging tool pins, and high-pressure braided material for hydraulic hoses

• Precision Tolerance Machining: CNC manufacturing with ±0.015mm dimensional accuracy, guaranteeing seamless docking with original equipment interfaces and eliminating installation rework

• Reinforced Durability Design: Anti-wear coatings on load-bearing parts, burst-resistant layers on high-pressure hoses, and dust-proof sealing for filter assemblies to extend service life

• Verified Service Life Data: Drill tong jaws withstand 1,200+ clamping cycles without deformation; MAN truck oil seals maintain leakproof performance for 35,000+ operating kilometers; logging tool sealing rings resist 28MPa downhole pressure without failure

Applicable Operating Conditions

• Oilfield Downhole Operations: -25°C to 90°C temperature range, 0-30MPa pressure environments, drilling fluid corrosion, and high-vibration downhole conditions for logging/inclinometer tools

• Heavy Truck Hauling: Long-haul highway use, off-highway oilfield roads, full-load continuous driving, and extreme weather fluctuations

• Drilling Rig Field Work: 24/7 continuous operation, high-torque mechanical loads, hydraulic pressure fluctuations, and dusty outdoor drilling sites

Maintenance & Engineer Practical Tips

• Replace MAN truck fuel filters and oil-water separators every 12,000 kilometers to prevent fuel system clogging; avoid mixing different grades of lubricants for seal components

• Inspect ZQ203 drill tong hydraulic hoses for cracks or bulges every 150 operating hours; torque hose fittings to specified values to avoid leakage

• Clean and lubricate inclinometer centralizer and hard connection assemblies before each downhole run; replace logging tool sealing rings in full sets to ensure uniform pressure resistance

• Store hydraulic hoses and rubber seals in a cool, dry area away from direct sunlight to prevent material aging; protect precision jaw assemblies from physical impact during storage
