Structural Features

Our spare parts are built to withstand the harshest oilfield conditions, with structural designs that prioritize durability, compatibility, and ease of use—all tailored to solve real on-site challenges:

• Precision Machining: Using advanced CNC machining technology, all parts have a dimensional accuracy of ±0.01mm, ensuring perfect fit with original equipment—eliminating installation delays caused by size deviations. For example, the SB56J0017 bearing has a dimensional tolerance of 6204, matching seamlessly with pump and topdrive shafts.

• High-Durability Materials: Critical parts (bearings, valves, casings) are made of alloy steel and stainless steel with quenching and tempering treatment, achieving a tensile strength of 830MPa—resisting impact, corrosion, and wear in high-pressure, high-temperature oilfield environments. Seals use nitrile rubber and wear-resistant materials, with excellent oil resistance and temperature tolerance (-40°C to 130°C).

• User-Friendly Design: Parts like the CLEVIS PIN WITH HEAD DBS75-2-09 feature a head design for easy installation and removal, reducing on-site labor time by 30 minutes per use. Complete kits (like 123584-3) include all necessary components, eliminating the need to source individual parts and reducing installation errors.

• Safety & Compliance: All parts comply with API 6A (Twenty-First Edition, Addendum 3) and GB 1235 standards, ensuring safe operation in hazardous oilfield areas (Ex d IIB T3 Gb). For example, the Oring seal 115×3,1 GB 1235 is designed for BOP PPG 2FZ35-35, meeting pressure control requirements for wellhead equipment.

Applicable Working Conditions

Our spare parts are engineered to adapt to diverse oilfield environments, solving the problem of poor adaptability in extreme conditions and ensuring reliable performance where generic parts fail:

• Top Drive Systems: Parts like 107031-1AN (Varco TDS-11SA) and 110042 (NOV TDS-10SH) are ideal for continuous drilling operations with high loads (up to 520t) and high speeds (up to 125rpm), adapting to desert, offshore, and cold-weather environments.

• Pumps & Hydraulic Systems: Oil pump RGF1000-06.12.00, pump case W001-045-04-001 (2500SB68JC), and impeller W001-045-04-002 are designed for high-pressure pump operations (up to 5000PSI), suitable for mud pumps, hydraulic pumps, and fluid transfer systems in onshore and offshore oilfields.

• Drawworks & Winches: Brake disc JC503.02.03 (Drawworks JC-50) and Distributor gear XJFH 5/35-1000 (air winch) are built to handle heavy loads (up to 400t) and frequent start-stop operations, withstanding high vibration and wear.

• High-Pressure Wellhead Equipment: Oring seal 115×3,1 GB 1235 (BOP PPG 2FZ35-35) and Mud tube 722-10-0 (5000PSI) are designed for high-pressure wellhead operations, complying with API 6A pressure ratings (up to 35MPa) and resisting corrosion from drilling fluids.

• Emergency & Electrical Systems: Emergency Lighting Inverter INV-CCH08118-36 and CONTACTOR E10366 (24VDC, 25 HP) ensure reliable power supply in emergency situations, adapting to harsh oilfield electrical environments with IP67 protection.

Maintenance & Care Recommendations

Based on 17 years of on-site engineering experience, we provide practical, easy-to-follow maintenance tips to extend part life and reduce costs—avoiding common mistakes that lead to premature failure and unplanned downtime:

• Bearings (SB56J0017, 4500100201): Grease bearings every 200 working hours with lithium-based grease (NLGI Grade 2) to reduce friction and wear. Check for abnormal noise or overheating (temperatures above 75°C indicate issues)—a common mistake is neglecting grease maintenance, which shortens bearing life by 3,000+ working hours.

• Seals & Packing Kits (123584-3, 30182002500): Check seals every 300 working hours for leaks; replace packing kits when leakage exceeds 5 drops per minute (per industry standards). Clean the sealing surface with a non-abrasive cleaner before installation, and avoid using sharp tools—this prevents 75% of seal damage.

• Pump Components (RGF1000-06.12.00, W001-045-04-002): Filter hydraulic oil every 1,000 working hours (filter precision ≤10μm) to prevent impeller and pump case wear. Inspect impellers for corrosion or damage every 6 months—replace if blade wear exceeds 0.5mm to maintain flow rate.

• Fasteners (50008-12-C5D, 50005-8-C5D): Tighten bolts and screws to the recommended torque (150 N·m for 50008-12-C5D) using a torque wrench—over-tightening can crack components, while under-tightening causes loosening and vibration. Check fasteners every 500 working hours for looseness.

• Storage Tips: Store all parts in a dry, ventilated warehouse (temperature 5-25°C, humidity ≤60%); keep seals and gaskets in sealed packaging to prevent aging. Avoid storing metal parts near corrosive substances—this extends their service life by 2,200+ working hours. Label parts clearly with model numbers to avoid misselection during emergency repairs.
