What class does gas turbine oil 23699 fall under?

Gas turbine oil 23699 is classified under the Corrosion Inhibiting (CI) class. This type of oil is specifically formulated to provide protection against corrosion in the components of gas turbine systems. The presence of additives in this oil formulation helps to prevent the oxidation of metal surfaces and the degradation of oil over time, which could lead to potential failures in turbine operation.

Corrosion inhibition is essential in gas turbine systems because exposure to heat, moisture, and other operating conditions can lead to rust and corrosion, ultimately compromising equipment reliability. This property of the oil ensures that critical components are protected throughout their operational lifespan, enhancing performance and extending service intervals.

The other classes listed serve different purposes: Oxidation resistant oils focus on preventing degradation due to oxidation, whereas fire-resistant oils are engineered to reduce the risk of combustion and protect in high-heat situations. High-temperature oils are designed to maintain viscosity and lubrication qualities at elevated temperatures but do not inherently include corrosion protection in their primary function.
