*Test Parameters:

  1. Viscosity
  2. Viscosity Index
  3. Flash Point
  4. Pour Point
  5. Demulsification
  6. Copper Corrosion
  7. Acid Number
  8. Foam Characteristics
  9. Oxidation Characteristics
  10. Water Separation
  11. Rust Prevention
  12. Cleanliness

*Oxidation Stability Test : Turbine Oil Oxidation Stability Test (TOST) is a valuable tool in order to indicate oil life for lubricants that are continuously exposed to gross water contaminations, high temperatures, and air entrainment in field service.

ASTM D943 commonly referred to as Turbine Oil. Oxidation Stability Test (TOST), is widely used in the lubrication industry to evaluate the oxidation stability.

*Best Practices for Steam Turbine Lubrication:

  1. Keep Oil Clean, Cool and Dry
  2. Install High Capture Efficiency Breathers to your Oil Respective Oil Tanks
  3. Monitor returning bearing oil temperature regularly
  4. Maintain proper alignment
  5. Inspect for signs of foaming and/or Air Entrainment
  6. Install primary (return line) and secondary sampling points
  7. Perform regular oil analysis
  8. Routinely inspect sight glasses for level, foam, and water
  9. Keep tank headspace dry using blowers, condensers or instrument air
  10. Drain accumulated water regularly
  11. Use offline fluid conditioning for precision contamination control
  12. Regularly inspect for varnish, especially in gas turbines
  13. Protect against water and or detergent ingress during wash-down
  14. Inspect bulk delivery of new oil before acceptance
