Description
Sinopec Gas Turbine Oil is available in ISO viscosity grades 32, 46, and 68. Formulated with high-quality hydrogenated base oils and selected additives, it provides excellent high-temperature oxidation stability and sludge control performance. It is suitable for the lubrication of gas turbines and steam turbines.
Applications:
Sinopec Gas Turbine Oil is suitable for use in:
- Gas turbines and gas-steam combined circulation turbines.
- Gas turbines in the petrochemical and fertilizer industries.
- Steam turbines.
Features and Benefits:
- Excellent high-temperature oxidation stability prolongs the life of the oil and increases service intervals.
- Excellent control of sludge, deposits, and varnish prevents servo-valve sticking and blocking, ensuring smooth operation.
- Good air release properties protect against air entrainment, ensure optimum oil film thickness, and protect equipment components from cavitation.
- Good antifoaming properties avoid the build-up of foam and reduce oil leakage from the system.
- Good water separation properties ensure that oil/water emulsions are not formed, meeting the requirements of combined circulation gas turbines.
-
Excellent anti-rust and corrosion prevention properties protect equipment from rusting and corrosion, and extend equipment life.
