Oil tp 22s decoding. Turbine oil, main characteristics. Applied equipment and cleaning methods. Regeneration of used turbine oils. Application and useful properties
Turbine oils are designed for lubrication and cooling of bearings of various turbine units: steam and gas turbines, hydraulic turbines, turbocompressor machines. The same oils are used as working fluids in control systems of turbine units, as well as in circulation and hydraulic systems of various industrial mechanisms.
Turbine oils should have good oxidation stability, does not precipitate during long-term operation, does not form a stable emulsion with water, which can penetrate into the lubrication system during operation, protect the surface of steel parts from corrosive attack. The listed performance properties are achieved by using high-quality oils, using deep refining during processing and introducing additive compositions that improve the antioxidant, demulsifying, anticorrosive, and in some cases antiwear properties of oils.
turbine oil apply for lubrication of bearings and auxiliary mechanisms of turbine units (steam gas turbines, turbocompressor machines, hydraulic turbines, marine steam turbine installations and other similar types of equipment), as well as for operation in control systems of these machines as a hydraulic fluid.

Turbine oil TP 22S is a lubricant intended for use primarily in steam turbines. This is evidenced by the very designation TP, which means "steam turbines".
Application of oil TP 22S
In addition, turbine oil TP 22S is widely used in centrifugal compressors and turbochargers. The main reason for the use of turbine oil TP 22S is the need to improve the anti-wear properties of turbines, as well as compressors.
Due to its composition, this engine oil has become the most widely used in Russia and the CIS countries, thanks to which it began to be produced by the largest oil refineries in the country, such as Lukoil and others. It should be noted that TP 22C oils produced by Lukoil have two varieties - grades 1 and 2.
Due to its properties this turbine oil is excellent for use in gas turbines, steam as well as hydroelectric installations. It is also widely used in the operation of marine turbines, and often serves the operation of transmission mechanisms.
Turbine oil composition
Machine turbine oil TP 22S, the specifications of which are provided for by the technical conditions TU 38.101821-83, has a special composition, the reason for which is the raw material for the production of this oil.
As a rule, it is produced from crude oil with a fairly large capacity of sulfur and waxy compounds. The raw materials for the production of this turbine lubricant are purified by a special method, using selective solvents for cleaning. An important fact is that TP 22C oils do not contain additives with extreme pressure properties.
Like any other machine oil, TP 22C incorporates a certain package of additives that enhances its basic properties.
The main properties of this oil should be considered the following:
- high antioxidant resistance to precipitation formation;
- anticorrosive composition;
- high demulsibility.
Technical characteristics of turbine oil TP 22S
This oil has the following characteristics that determine its scope:
- Its kinematic viscosity is at different temperatures (50 and 40 degrees Celsius) values from 20 to 23 and from 28.8 to 35.2 mm² / s, respectively. In this case, the viscosity index of the oil is 90 units.
- The alkalinity of TP 22C has a fairly low value - up to 0.07 mg KOH / g, which makes it possible to largely avoid negative impact oxidative processes.
- According to the specifications, the pour and flash point in an open crucible forms a range from minus 15 to plus 186 degrees Celsius, at which oil operation is possible, which ensures the operation of turbines with a sufficiently large amount of excess heat.
- In addition, TP 22C does not contain acidic or alkaline compounds, mechanical additives, or phenol at all. But at the same time, turbine lubricant contains sulfur substances at a level of up to 0.5%.
These oils have a fairly high stability against oxidation. As an example, the mass fraction of sediment is not more than 0.05 ppm.
This and other indicators are the lowest among analogues, which allows this turbine oil to remain the most used among other types of lubricants for turbine installations.

The turbine oils subgroup includes petroleum lubricating oils used for the lubrication and cooling of turbines and turbine sets.
In the designation of a number of brands of turbine oils, the regulatory and technical documentation provides for the following procedure:
the letter "T" - defining the belonging of the oil to a subgroup of turbine oils;
digital designation - characterizing the level of kinematic viscosity of the oil at a temperature of 50 0 С.
For example: T 22 - turbine oil with a kinematic viscosity at 50 0 C, in the range of 20-23 mm 2 / s.
In addition, after the letter “T”, for a number of brands, the letter “p” is introduced into the designation, which means the presence of an additive composition in this brand of oil, for example: Tp-30.
Turbine oils of grades T 22, T 30, T 46, T 57 that do not contain additives are produced in accordance with GOST 32-74 “Turbine oils. Specifications» from high-quality low-sulphur, paraffin-free Baku oils by acid cleaning. The required level of performance properties of oils is achieved by the choice of raw materials and the depth of purification.
The scope of turbine oils is mainly determined by their composition and level of viscosity properties. So, for use in high-speed steam turbines, turbo- and centrifugal compressors, oils of the T 22, Tp-22S, Tp-22B brands are used; ship steam turbines T 46 and Tp-46.
Characteristics of turbine oils are presented in table. 3 and 4.
Oils Tp-22, Tp-30 and Tp-46 according to GOST 9972-74 “Petroleum oils with additives. Specifications" with rev. 1-9 are produced from waxy oils using selective solvent cleaning. The required level of performance properties of oils for various purposes is achieved by introducing into their composition an appropriate complex of additives with antioxidant, anticorrosive and demulsifying properties.

- maximum pour point of oil - "minus" 17 degrees Celsius;
- the percentage of sulfur in the composition of the oil is not more than 0.06 percent.
Advantageous features of TP oil
The oil of the line of lubricating fluids Tp, including Tp-22s, incorporates a complex of special additives that can ensure reliable performance of the equipment. In particular, it is approved and used at power generating stations of RAO UES. At the same time, it has such competitive advantages during application:
- exhibits high parameters of resistance to oxidation processes;
- possesses resistance to preservation of anticorrosive properties;
- not subject to foaming, being among the rotating parts of the equipment;
- has a good demulsifying ability;
- reliably and efficiently protects turbine shafts and their bearings from wear.
TP oil decoding
Turbine oils are marked with the letter indices "Tp" or "T" and a combination of numbers and letters that classify their intended use, in particular, TP-22s means that this is a turbine oil intended for high-speed turbines and centrifugal compressors. It has a wide range of applications and is therefore the most common.
TP 22 oil analogs
An analogue of Tp-22s in terms of the scope of the lubricating fluid is T30 oil.
operation of turbine oil tp 22s
Turbine oils operate under severe operating conditions, but the lubricant must not be allowed to overheat by using various cooling systems.
oil overheating tp 22s consequences
Overheating of turbine oil leads to such negative consequences as “oil aging”, which manifests itself:
- in increasing the oxidation of the lubricating fluid;
- in increasing the viscosity parameters;
- leads to a decrease in the flash point;
- and decrease in deemulsion properties.
