Gas Turbine Specific
Features excellent high-temperature oxidation resistance and anti-wear performance, suitable for high-temperature and high-pressure operating environments, ensuring stable equipment operation under severe conditions.
Product Performance: Gas turbines, characterized by energy efficiency and high power output, expose lubricating oil to high-temperature surfaces during operation, where it mixes with air (flue gas), is pumped and circulated at considerable rates, and operates under high pressure. Therefore, gas turbine oils require superior high-temperature oxidation stability and anti-wear properties compared to steam turbine oils. Application: Suitable for bearing lubrication of various smoke turbines without gear connections, also applicable for smoke turbines with an inlet temperature of approximately 800°C, as well as large gas turbines operating at 1100-1300°C.
