Oil IGP-91 (TOR 38.101413-97) is a distillate oil, residual oil or a mix of distillate and residual oils from sulfurous petroleums of deep selective clearing with antioxidizing, wear-protective, anticorrosive and antifoam additives.
This oil usually is used for greasing of the modern domestic and import equipment in various branches of a national economy for which operation oils with the improved operational properties are necessary.
Oil IGP-91 is used in hydraulic systems of heavy pressure equipment and for greasing gear transfers, middle-loaded gear and worm reducers, in circulating systems of grease of the various equipment.
The basic indicators characterizing operational properties of oils IGP are viscosity, stability against oxidation, anticorrosive properties and firmness to foaming.

Kinematic viscosity, cSt, at 40 °?, not less than: 148-165
Mass fraction of zinc, %, not less than: 0.04
Mass fraction of sulfur, %, not less than: 1
Flash temperature, in an open cup, °C, not lower than: 225
Hardening temperature, °C, not above: -15

Data on operational temperatures represent values, which are guided by a structure of lubricants, and also on a scope and technology of use. Depending on a kind of mechanical-dynamic loading lubricants change the consistence, conditional viscosity or viscosity at various temperatures, pressure and duration of operation. These changes of indicators can affect work of components.

Oil IGP-38 (TOR 38.101413-97) is distillate oil, residual oil or a mix of distillate and residual oil oils from sulfurous petroleums of deep selective clearing with antioxidizing, wear-protective, anticorrosive and antifoam additives.
The oil usually is used for greasing of the modern domestic and import equipment in various branches of a national economy for which operation oils with the improved operational properties are necessary. Oil IGP-38 serves as a working liquid in hydraulic systems of machine tools, automatic transfer lines, presses.
Use this oil for greasing of high-speed transmissions, variable-speed transmissions, electromagnetic and gear couplings, bearing sites, plain slide ways and roller guide way and in other sites and mechanisms where oils with the improved antioxidizing and wear protective properties are required. The basic indicators characterizing operational properties of oils IGP are viscosity, stability against oxidation, anticorrosive properties and firmness to foaming.

Oil I-50A (GOST 20799-88) is a distillate oil or a mix of distillate oil with residual from sulphurous and low-sulphur petroleums of selective clearing.
It used as working liquids in hydraulic systems of the machine-tool equipment, automatic transfer lines, presses, for greasing it is easy — also middlingloaded tooth gearings, slideways bearing and sliding of machine tools where it is not required special oils, and other mechanisms. Most widely apply oil ?-50? in hydraulic systems of the industrial equipment, to the building, road and other machines working on open air.
Application specified oils in those or other mechanisms depends on their viscosity: in process of its increase in oil use in more loaded and less high-speed mechanisms. It is possible to replace the specified oil with alloyed oils ???-18, ???-30, ???-38 and ???-49 (THAT 38) corresponding viscosity.

Data on operational temperatures represent values which are guided by a structure of lubricants, and also on a scope and technology of use. Depending on a kind of mehaniko-dynamic loading lubricants change the consistence, conditional viscosity or viscosity at various temperatures, pressure and duration of operation. These changes of indicators can affect work of components.

Oil I-12A (GOST 20799-88) is distillate oil, produced is from sulfurous petroleums of selective clearing. Serves for greasing of plugs, bearings of spindles roving and other machines, sites full-fashioning and looping machines, spindles of the metal-cutting machine tools working with frequency of rotation to 5 thousand of mines-1, for directing grandmas of filler-boring, filler-polishing and other machine tools, for bearings of low-power electric motors with ring system of grease, as working liquids in the volume hydro drives working indoors and outdoors for piston group of ammoniac compressors and for many other things equipment kinds.
The oil is also used for manufacturing of oils with additives, plastic antifriction and conservation greases, emulsifying structures, technological greases and liquids.
