Each component undergoes strict quality testing to match or exceed original equipment standards, ensuring minimal downtime, reduced maintenance frequency, and improved operational efficiency. We supply over 50 types of oilfield spare parts, covering hydraulic systems, transmission components, sealing parts, electrical parts, and structural components, supporting both onshore and offshore oilfield operations.

Product Overview

Key Product Models & Functional Explanations

Our product line covers a wide range of oilfield spare parts, each designed to address specific operational challenges. Below are the core models and their practical functions:

• HYDRAULIC CYLINDER H18-1506-001 & 205PZL029D: These hydraulic cylinders are built to withstand high pressure and heavy loads, solving the problem of cylinder leakage and insufficient lifting force in oilfield equipment. They are compatible with top drive systems, winches, and drilling rigs, with a maximum working pressure of 35MPa and a service life of 8,500 working hours—1,200 hours longer than standard cylinders.

• VARCO AUX POWER CONNECTOR 114729-SL-676-20: This inline socket connector ensures stable power transmission for oilfield electrical equipment, avoiding power interruptions caused by poor contact. It is designed for 19C QD specifications, with IP67 protection rating to resist dust and water, suitable for harsh oilfield environments.

• Weatherford Jaw set 109589-002 (12 3/4″, 324 mm): Specifically designed for Weatherford tongs, this jaw set provides strong clamping force (up to 120kN) to prevent pipe slipping during drilling, solving the problem of frequent jaw wear and replacement. It is made of high-strength alloy steel, with a wear resistance of 6,800 clamping cycles.

• Sealing Parts (O-RING S01-1267-01N, ABCO 602/1002 SEAL-4.0 BUNA, W001-045-02-015 oil seal): These sealing components prevent fluid leakage in hydraulic systems, gear boxes, and pipelines. The O-rings are made of Buna material with high temperature resistance (-40°C to 120°C) and oil resistance, while the 63.5*88.8*12 oil seal (Kit20619) solves the problem of oil leakage in rotating shafts, with a sealing life of 5,200 working hours.

• Top Drive Components (124517-502 BEAM, 120262-1 Adjusting shim): Compatible with NOV TDS-10SH top drive systems, the intermediate beam ensures stable power transmission, while the adjusting shim maintains precise alignment of moving parts, reducing vibration and extending the service life of the top drive by 2,000 working hours.

Structural Features

All our spare parts adopt industry-leading structural designs to adapt to the harsh oilfield environment:

• High-Strength Material: Key components (such as jaw sets, shafts, and bolts) are made of alloy steel with quenching and tempering treatment, ensuring tensile strength of up to 800MPa and resistance to corrosion and impact.

• Precision Machining: Using CNC machining technology, the dimensional accuracy of each part is controlled within ±0.02mm, ensuring perfect compatibility with original equipment and avoiding installation difficulties caused by size deviations.

• Sealing & Protection: Sealing parts adopt double-layer sealing structure, and electrical components are equipped with explosion-proof and waterproof designs, meeting the safety requirements of oilfield hazardous areas (Ex d IIB T3 Gb).

• Modular Design: Components such as rapid change assy 12048-00 and packing gland set W001-045-04-042 adopt modular design, making installation and replacement faster, reducing maintenance time by 40 minutes per operation on average.

Applicable Working Conditions

Our spare parts are widely applicable to various oilfield working conditions, solving the problem of poor adaptability of ordinary parts in harsh environments:

• Onshore & Offshore Drilling Rigs: Suitable for high-temperature (up to 150°C) and high-pressure (up to 40MPa) environments, resistant to salt spray and humidity, applicable to offshore platforms and desert oilfields.

• Top Drive Systems: Compatible with NOV TDS-10SH and other top drive models, suitable for continuous drilling operations with high load (up to 500t) and high speed (up to 120rpm).

• Hydraulic Systems: Hydraulic cylinders, valves (BK-FY Overflow valve, P614000063-IAN Relief Valve), and motors (CMN135) are suitable for hydraulic systems of drilling rigs, winches, and tongs, adapting to frequent start-stop and heavy-load operations.

• Electrical Equipment: Explosion-proof magnetic starter BQD58-15kW (380VAC/50HZ) and VARCO power connector are suitable for oilfield hazardous areas, ensuring safe and stable operation of electrical systems.

Maintenance & Care Recommendations

To extend the service life of spare parts and reduce maintenance costs, our engineers provide practical operation suggestions based on 15 years of on-site experience:

• Sealing Parts: Check O-rings and oil seals every 300 working hours; clean the sealing surface before replacement to avoid scratches, and apply special lubricating oil (model: 32# anti-wear hydraulic oil) to prevent aging. Avoid using sharp tools during installation to prevent damage to the sealing lip.

• Hydraulic Components: Regularly filter hydraulic oil (filter precision ≤10μm) to avoid impurity wear of cylinder inner walls and valve cores; check hydraulic cylinder rod surface for scratches every 500 working hours, and apply anti-rust oil if necessary.

• Mechanical Components (Jaw sets, Bearings): Grease bearings (100151-001) every 200 working hours with lithium-based grease; replace jaw sets when the wear depth exceeds 0.5mm to avoid pipe slipping. Do not overload the jaw set beyond its rated clamping force (120kN).

• Electrical Components: Clean the surface of explosion-proof magnetic starters and power connectors every 10 days to remove dust and oil; check the wiring terminals for looseness to avoid poor contact. Do not disassemble electrical components in hazardous areas without power cut.

• Storage: Store spare parts in a dry, ventilated warehouse with a temperature of 5-25°C and humidity ≤60%; avoid direct sunlight and contact with corrosive substances. Sealing parts should be stored in sealed packaging to prevent aging.
