All-Union State Standards 9972-74
Turbine Oils with Additives Тp-22, Тp-30 and Тp-46 are used for greasing bearings and auxiliary mechanisms of turbo-units including steam gas turbines, turbocompressor machines, water turbines, ship’s steam turbine units and other analogous types of equipment. These oils are also utilized as hydraulic liquids for working with regulating systems of the mentioned machines.
Guarantee period of storage – 5 years from the day of manufacture.
