1. Basic Information and Core Performance

• Developer: Sinopec Research Institute of Petroleum Processing (RIPP), a strategic product for domestic substitution.

• Temperature Range: -40°C to 180°C, with short-term tolerance up to 200°C.

• Standards: Complies with Q/SY16051-1976, partially aligned with military standard GJB-1263-1991.

• Key Performance:

• High-Temperature Oxidation Resistance: Reduces bearing wear and extends gear life (lab oxidation induction period >300h at 180°C).

• Extreme Pressure (EP) Load Capacity: Four-ball test PB value ≥1200N, suitable for high-load gear meshing.

• Low Acid Value: Acid value <0.1mg KOH/g (superior to Shell 555’s 0.15mg KOH/g), mitigating metal corrosion.

2. Core Application Scenarios and Case Studies

(1) Helicopter Transmission System Lubrication (Primary Application)

• Main Reducer and Drive Shaft:

• Case Study: Reduced gear pitting failure rate by 15% in Russian-made Mi-17 helicopter main reducers (field-tested at Xinjiang Army Aviation Base).

• Advantage: Maintains lubricant film stability in high-altitude, low-oxygen, and high-UV environments (validated in Qinghai-Tibet Plateau operations).

• Tail Rotor Drive Shaft Protection: Withstands localized transient high temperatures (180–200°C), minimizing sludge formation.

(2) Military-Civilian Integration

• Military Emergency Support: Shortened oil change cycles by 20% during high-intensity training (single maintenance time reduced from 4h to 3.2h).

• Domestic Helicopter Compatibility: Met low-temperature startup requirements (-40°C viscosity ≤4500cP) in trials for upgraded Z-20 transmission systems.

(3) Industrial Equipment Applications

• Wind Turbine Gearboxes: Reduced sludge generation by 30% compared to mineral oils in 2.5MW turbine high-temperature tests.

• High-Speed Rail Traction Motor Bearings: Extended bearing lifespan by 15–20% under transient 200°C thermal shocks.

3. Market Comparison and Competitive Analysis

Summary

The core application scenarios of RIPP 4051 focus on high-temperature, high-load lubrication of helicopter drive systems, and at the same time show potential in general aviation maintenance, military-civilian integration support, and industrial equipment life extension. Its actual value is reflected in the cost advantage of localization substitution and extreme environmental adaptability, and can be further expanded to the field of high-end equipment through performance optimization in the future.
