Overview
Turbine oil is a lubricant for water, steam and gas turbines made from base oils and special additives, offered in standard and Plus versions. Grades: T-32, T-46, T-68, T-100, T-32 Plus, T-46 Plus, T-68 plus.
The specification table lists each grade separately, with the test method for every value, so grades can be compared directly before ordering.
Application
Turbines whose manufacturer specifies the viscosity offered.
Feature
T-32: KV100 5.3 cSt, VI 100, pour point -18 °C, flash point 210 °C; T-46: KV100 6.8 cSt, VI 100, pour point -15 °C, flash point 215 °C; T-68: KV100 8.7 cSt, VI 100, pour point -12 °C, flash point 220 °C; T-100: KV100 11.4 cSt, VI 100, pour point -12 °C, flash point 230 °C; T-32 Plus: KV100 5.8 cSt, VI 128, pour point -24 °C, flash point 210 °C; T-46 Plus: KV100 7.3 cSt, VI 130, pour point -24 °C, flash point 210 °C; T-68 plus: KV100 9.9 cSt, VI 130, pour point -24 °C, flash point 210 °C.
Feature
The Plus versions publish a higher viscosity index (about 128–130) than the standard versions (100) at the same viscosity class.
Follow the equipment manufacturer's viscosity recommendation at operating temperature, then compare the grades' published values in the specification table.
Next step
The range above is what we publish. Formulation to a customer brief is a route of its own, and a sample is the first stage of it.
