1. Basic Properties and Standards

• Product Type: Aviation-grade lubricating grease designed for high-temperature threads, bolts, and fasteners, providing protection and lubrication.

• Standards Compliance: Meets the enterprise standard Q/SH3360021-2011. Some references also mention alignment with national standards (GB), depending on application scenarios.

• Packaging: Typically available in 1 kg or 3 kg containers.

2. Key Performance Features

• High-Temperature Resistance: Operates effectively in a wide temperature range of -40°C to 1100°C. Maintains adhesion and lubrication without thinning, melting, or leakage. Formulated with partial benzene ester synthetic oil, which minimizes carbon residue and ensures thermal stability.

• Protection: Prevents thread wear, cold welding, galling, and sintering. Particularly effective for anti-seizure applications in high-temperature bolts, such as automotive exhaust flanges and aerospace equipment.

• Water Resistance & Anti-Corrosion: Retains a stable lubricating film in humid or water-contaminated environments. Free from aluminum, lead, copper, sulfur, and fluorine, ensuring no corrosion to metal components.

• Longevity: Maintains consistent torque performance even after repeated disassembly and reassembly, reducing maintenance frequency.

3. Applications

• Aerospace & Military: Widely used in fire control systems, aircraft instruments, gears, lead screws, and high-temperature bolts.

• Industrial High-Temperature Environments: Suitable for boilers, turbines, valves, and other high-pressure equipment in power plants, metallurgy, and petrochemical industries.

• Automotive Industry: Applied to spark plug threads, oxygen sensors, and brake friction components requiring high-temperature assembly lubrication.

4. Comparison with Competing Products

• RIPP 7455: The 7451 variant is optimized for aerospace applications, while the 7455 focuses on broader industrial use.

• Sinopec Great Wall 7409 Drill Lubricant: The 7451 offers a superior temperature range (-40°C to 1100°C vs. -15°C to 200°C) and excels in extreme heat scenarios.

• Competitors: Products like Caidon GP1100 and Ecco HT1400 claim similar 1100°C tolerance, but the 7451 has more authoritative validation in aerospace applications.

5. Usage Recommendations

• Dilution Ratio: Mix with water at 1:10 or 1:30 ratios. Use low-mineral water to extend working fluid lifespan.

• Operational Guidelines: Always add the concentrate to water (never reverse). Adjust concentration based on evaporation and consumption rates during routine maintenance.

6. Strengths and Limitations

• Strengths: Exceptional temperature adaptability, military-grade reliability, and versatility across industries.

• Limitations: Does not explicitly mention low-temperature extreme-pressure performance (compared to Shiyou Academy 7253, which operates at -73°C). Regular maintenance is still required despite low carbon residue.

Summary

The RIPP 7451 High-Temperature Thread Lubricating Grease is a benchmark product for extreme-heat scenarios, offering 1100°C tolerance, anti-seizure performance, and military-grade durability. It is ideal for critical applications demanding stability and longevity. Users should select standards (GB or enterprise) based on specific conditions and consider complementary use with low-temperature or extreme-pressure greases for comprehensive protection.
