Description
Sinopec L-TSA Turbine Oil (Grade A) is available in ISO viscosity grades 32, 46, and 68. Formulated with high-quality base oil and selected additives, it offers good oxidation stability and corrosion protection along with good demulsibility, antifoaming, and air release properties.
Applications:
Sinopec L-TSA Turbine Oil is suitable for use in:
- Steam turbines used in industrial power generation.
- Large to moderate marine steam turbine propulsion machinery and associated auxiliary equipment.
- Industrial steam turbines, gas turbines, and water turbines.
- Circulating systems, anti-friction bearings, enclosed gears, hydraulic units, and other industrial applications, providing there is no requirement for antiwear additives.
Features and Benefits:
- Good oxidation stability prolongs the service life of the oil and increases service intervals.
- Good air release properties protect against air entrainment and ensure optimum oil film thickness, protecting equipment components.
- Good antifoaming properties avoid the build-up of foam and reduce oil leakage from the system.
- Good water separation properties ensure that any water contamination can be easily separated from the oil, protecting equipment against rusting and corrosion and extending oil life.
- Anti-rust and corrosion prevention properties further protect equipment from rusting and corrosion and extend equipment life.
