Marine hardware anti-corrosion lubrication
Lubrication of parts exposed to moisture or salinity
Also known as: Graphite lubricant for marine environments · Anti-corrosion lubrication of brakes and hardware · Anti-friction for parts in salinity · Lubricant for moisture-exposed hardware
Graphite film for marine hardware exposed to moisture or salinity.
[ Technical summary ]
In marine service, hardware sees moisture and salinity. Grease washes off or traps salts and stops protecting the contact. A graphite film lubricates and reduces bare metal exposure. This record covers marine hardware; ports and railway are separate uses. It does not replace a paint anti-corrosion coating when the equipment standard requires one.
Each process needs a specific product and application method. ESGRAF selects the solution according to temperature, material, load, cycle, and application method.
[ Problem it solves ]
Lubricate marine hardware exposed to moisture or salinity without grease that washes off or traps salts.
Processes
- Marine-hardware maintenance
- Lubrication of contacts exposed to salts
Operating conditions
- Moisture and salinity
- Outdoor hardware
When it is suitable
- Grease washes off or traps salts
- Hardware seizes with corrosion and dirt
- The contact must stay lubricated outdoors
When it may not be suitable
- The equipment standard requires a different anti-corrosion coating
- There is advanced corrosion that requires repair
- The surface tolerates no black residue and there will be no cleaning stage
Process challenges
- Lubricant wash-off
- Salts in the contact
- Seizing from corrosion
Advantages
- Film that does not wash off like a light oil
- Reduces bare metal in the contact
- Useful on outdoor hardware
Limitations
- Does not replace an anti-corrosion paint when the standard requires one
- Does not repair advanced corrosion
- Reapplication follows inspection
