TURBINE OILS according to All-Union State Standard 32-74 ALL-UNION STATE STANDARD 32-74
Turbine oils Т22, Т30, are used for greasing of bearings and auxiliary machinery turbines (steam and gas turbines, turbo machinery, turbines), as well as to work in control systems of these machines as a hydraulic liquids.
Turbine oils Т46 и Т57 are used in the ship steam-turbine plants (geared-turbine sets) and other auxiliary ship mechanisms with hydraulic.
