1. Basic Properties and Standards Compliance

• Product Type: High-temperature thread lubricating grease designed for heavy-duty, high-temperature threaded connections (e.g., bolts, nuts, threads), offering anti-seizure, anti-wear, and anti-sintering properties.

• Standards Compliance: Meets the enterprise standard Q/SH360019-2010, with adaptability to general industrial standards (e.g., GB standards) for specific applications.

• Packaging: Typically available in 3 kg containers, with bulk options (3 kg × 6 containers per box).

2. Key Performance Features

Core Advantages

1. High-Temperature Stability:

• Operating Temperature Range: -20°C to 400°C, with long-term durability in high-temperature environments. Short-term tolerance up to 400°C for fixed thread protection.

• Base Oil: Formulated with partial benzene ester synthetic oil, exhibiting low carbon residue (tested steel mesh oil separation rate: 2.3%) and resistance to leakage or carbonization at high temperatures.

2. Anti-Seizure and Anti-Wear Properties:

• Contains solid extreme-pressure additives (e.g., molybdenum disulfide), effectively preventing cold welding, galling, and sintering in threaded connections under heavy loads (e.g., heavy machinery bolt assembly).

• Passes 100°C corrosion testing on 45# steel plates, confirming non-corrosiveness to metals.

3. Eco-Friendliness and Safety:

• Free from heavy metals (lead, copper, aluminum), sulfur, fluorine, and other harmful components, compliant with industrial environmental regulations.

4. Long-Term Lubrication and Reduced Maintenance:

• Strong adhesion and minimal leakage (evaporation rate: 0.9%), reducing the need for frequent re-greasing.

• Pressure-induced oil separation rate of 2.9% ensures stable lubricating films under dynamic loads.

Limitations

• Limited Low-Temperature Performance: Lower temperature limit of -20°C; requires complementary low-temperature greases (e.g., Shiyou Academy 7253, rated for -73°C) in extreme cold environments.

• Comparison with Competing Products:

• Compared to RIPP 7451 (-40°C to 1100°C), the 7455 is better suited for medium-high temperature industrial applications (≤400°C), while extreme heat scenarios demand upgrades to 7451 or Ecco HT1400.

• Unlike Fuchs RENOLIT COPPER PASTE (contains copper powder), the 7455 avoids copper-induced corrosion but may lack suitability for high-conductivity applications.

3. Application Fields

• Industrial Equipment:

• Bolts in thermal power plant boilers, high-temperature valves in petrochemical facilities, and threaded connections in metallurgical equipment.

• Low-speed, high-load rolling/sliding friction components (e.g., large bearing break-in operations).

• Automotive Manufacturing:

• Exhaust pipe flanges, spark plug threads, and oxygen sensor assembly lubrication to prevent high-temperature sintering.

• Aerospace:

• Mid-to-high-temperature bolt protection in rockets, missiles, and similar equipment (non-extreme heat scenarios), partially replacing RIPP 7457 grease.

4. Usage and Storage Guidelines

• Operational Instructions:

1. Cleaning Requirements: Thoroughly clean the lubrication area before application to avoid contamination.

2. Compatibility: Do not mix with other brands or types of grease to prevent performance degradation.

3. Dilution Recommendations:

• For dilution, follow general high-temperature thread grease ratios (e.g., 1:10 or 1:30 with water), using low-mineral water to extend service life.

• Slowly add the concentrate to water; reverse mixing is strictly prohibited.

• Storage Conditions:

• Store in sealed containers in dry, waterproof environments away from direct heat or extreme humidity.

5. Competitive Analysis and Market Positioning

6. Cost-Effectiveness and Market Feedback

• Price Drivers: Subject to fluctuations in RIPP’s production capacity, raw material costs (e.g., synthetic esters), and industrial demand cycles.

• User Reviews:

• Strengths: High cost-effectiveness in sub-400°C applications, excellent anti-seizure performance, ideal for frequently disassembled industrial bolts.

• Improvement Requests: Some users recommend enhancing low-temperature performance for broader applicability (e.g., winter operations in northern regions).

Summary and Selection Guidance

The RIPP 7455  Thread Lubricating Grease is a top choice for medium-high-temperature industrial scenarios, excelling in automotive, power generation, and petrochemical sectors with its anti-seizure properties, low carbon residue, and eco-safety. 

Key considerations for selection:

1. Temperature Matching: Upgrade to 7451 or 7253 for conditions exceeding 400°C or requiring extreme cold tolerance.

2. Competitor Substitution: Consider Fuchs RENOLIT COPPER PASTE for copper-based or conductive needs, but assess corrosion risks.

3. Maintenance Strategy: Regularly inspect lubricating film integrity and adjust re-greasing frequency based on operational conditions. Avoid mixing with other greases.

With proper application, the 7455 significantly extends the lifespan of threaded connections, reduces maintenance costs, and delivers a reliable solution for industrial lubrication.
