Operating in challenging conditions, industrial lubricants face exposure to elevated temperatures. This requires the selection of lubricants that not only provide effective lubrication but also withstand the rigors of high heat environments, ensuring machinery longevity.
Flash Point
When lubricants are exposed to high temperatures, usually above 200°C, they release vapors that can catch fire when they come into contact with air or an ignition source. This moment of ignition is known as the Flash Point. Although it doesn’t directly impact a lubricant’s performance or quality, it’s important to choose a lubricant with a lower temperature exposure than its Flash Point for safety reasons.
Fire Point
Closely related to Flash Point, the Fire Point is the temperature at which a lubricant sustains combustion. This metric goes beyond ignition, offering insights into the lubricant’s ability to resist further combustion. It acts as a key marker for assessing the overall safety of lubricants in high-temperature applications.
Auto-Ignition Temperature
Auto-Ignition Temperature is the lowest temperature at which a substance can spontaneously ignite without an external ignition source. For instance, the auto-ignition temperature of diesel fuel is approximately 256°C (492°F). If diesel fuel reaches this temperature, it will ignite on its own, without any external flame or spark.
Safety When Using Lubricants
When considering lubricant safety, mineral-based and synthetic lubricants emerge as safer alternatives compared to solvents and highly volatile mineral spirits, especially fluids with Flash Points at 40°C or lower. These lubricants inherently possess properties that reduce the risk of ignition, ensuring a safer working environment for machinery and personnel alike.
Fire-Resistant Hydraulic Fluids
Tailored for high-temperature applications, fire-resistant hydraulic fluids add an extra layer of safety to industrial operations. Their unique characteristics minimize the risk of ignition, making them ideal for machinery operating in environments where conventional lubricants may pose heightened risks.
Consult with Lubrication Experts
In navigating the complexities of lubricant selection and application, seeking the expertise of lubrication professionals becomes a strategic move. These experts bring in-depth knowledge of lubricant properties, machinery intricacies, and practical application aspects. Consulting with them ensures informed choices, aligning lubricant selection with specific industrial needs.
