Turbine oil TP-22S. Specifications

Composition

The basis for the production of turbine oil TP-22s are oils that do not contain sulfur compounds at all (or in a minimal amount). At the same time, up to 97% of the composition is the base oil, and the rest is various additives, which include:

  • corrosion inhibitors;
  • antioxidants;
  • anti-foam components;
  • demulsifiers.

These additives are blended into the base oil at low levels to protect both the oil and turbine components from harmful external factors. Additives are selected so that they provide optimal performance in the turbine according to the technical requirements for its operation. Data from laboratory tests show that the use of the above components provides a longer lubricant life, which is reflected in its increased thermal stability and resistance to chemical and mechanical effects of the smallest particles - wear products.

Physical and mechanical parameters

The main document for turbine oil TP-22s is GOST 32-74, which specifies the main characteristics of this oil in its pure form, without additives. For the direct manufacturers of the product, TU 38.101821-2001 serve as governing regulatory documents, which are periodically agreed and confirmed by the main manufacturers. Oils marked as TP-22s, but not having such confirmations, are considered counterfeit and do not guarantee the necessary performance of components and mechanisms.

Turbine oil TP-22S. Specifications

According to the specified specifications, turbine oil TP-22s is produced with the following final indicators:

  1. Kinematic viscosity, mm2/ s: 20… 35.2.
  2. Viscosity index limits: 90…95.
  3. Acid number, in terms of KOH: 0,03 ... 0,07.
  4. The presence of sulfur,%, not higher: 0,5.
  5. The minimum flash point outdoors, °C, not below:
  6. thickening temperature, °C, not higher: — 15…-10°C.
  7. Density at room temperature, kg/m3 - 900.

The composition of the product does not allow the presence of water and phenolic compounds, as well as acids and alkalis that dissolve in water.

To comply with international standards (in particular, ASTM D445 and DIN51515-1), turbine oil TP-22s is produced in two groups - 1 and 2, and the oil of the first group has improved antioxidant characteristics.

Application

Like oil TP-30, which is related in properties, the oil product in question is resistant to high temperatures and pressures, when the risk of formation of varnishes and mechanical sediment, which worsen friction conditions, increases. Particular importance is attached to the possible vaporization, since this worsens environmental performance.

The optimal area for using TP-22s turbine oil is considered to be turbine units of small and medium power. In more severe operating conditions, the viscosity of the oil is insufficient to form a stable oil film on the surface of steel parts, which effectively separates areas with increased sliding friction.

The price of an oil product is determined by its packaging:

  • wholesale (barrels of 180 l) - 12000… 15000 rubles;
  • wholesale, in bulk (per 1000 liters) - 68000… 70000 rubles;
  • retail - from 35 rubles / l.
