Turbine & Industrial Oils

turb 2


Industrial lubricants specially Turbine oils are a very important part of Iran's very large market. Yekta group, considering the 30 years of experience in the oil industry, the urgent need of the heavy industries, gas, petrochemical and power plant industries, designed and formulated a new turbine, hydraulic and compressor gear oil, so that each of these lubricants has low ash (Ash) and Sulfur is very low and will not have corrosive and abrasive effects in the workplace, and the additives for industrial lubricants produced by this company are all with international certifications and world quality.

Industrial oils including turbine oil, hydraulic oil, agricultural oil, marine oil, industrial gear oil, industrial greases have occupied a large and important market in the global lubricant industry.
---Turbine oils are widely used in commercial aviation, military aviation, petroleum transportation & refineries,   development of gas transmission pipelines by petroleum pipelines and large ships and aircraft carriers.


---Also, hydraulic oil has various and vital applications in heavy industries, large factories, power plants, commercial   aircraft, military jets, transportation and mines, and the automotive industry.
---And Large factory automation department
---Agricultural oils are used for agricultural machinery and tractors.
---Marine oils including tankers, military ships, merchant and transport.




industrial lubricants are very important to developing of big and heavy industries around of world.and turbine oil have a strategic efect to oil & gas  , military jets , commercial jets,petroleum transferring by pipeline,...



For most large gas turbine frame units, high operating temperature is the leading cause of premature turbine oil failure. The drive for higher turbine efficiencies and firing temperatures in gas turbines has been the main incentive for the trend toward more thermally robust turbine oils.
Today’s large frame units operate with bearing temperatures in the range of 160ºF to 250ºF (71ºC to 121ºC).

Next-generation frame units are reported to operate at even higher temperatures. Gas turbine OEMs have increased their suggested limits on RPVOT - ASTM D2272 (Rotation Pressure Vessel Oxidation Test) and TOST - ASTM D943 (Turbine Oil Oxidation Stability) performance to meet these higher operating temperatures.

Hydro turbines typically use ISO 46 or 68 R&O oils. Demulsibility and hydrolytic stability are the key performance parameters that impact turbine oil life due to the constant presence of water. Ambient temperature swings in hydroelectric service also make viscosity stability, as measured by viscosity index, an important performance criterion.

Aero-derivative gas turbines present unique turbine oil challenges that call for oils with much higher oxidation stability. Of primary concern is the fact that the lube oil in aero-derivative turbines is in direct contact with metal surfaces ranging from 400ºF to 600ºF (204ºC to 316ºC). Sump lube oil temperatures can range from 160ºF to 250ºF (71ºC to 121ºC).

These compact gas turbines utilize the oil to lubricate and to transfer heat back to the lube oil sump. In addition, their cyclical operation imparts significant thermal and oxidative stress on the lubricating oil. These most challenging conditions dictate the use of high purity synthetic lubricating oils.
Average lube oil makeup rates of .15 gallons per hour will help rejuvenate the turbo oil under these difficult conditions.

changing turbine oil depend on  quality control engineer & lubrication experts. you must controlling  each day ,each month ,each year by condition monitoring program. you never change turbine oil ISO 32 to ISO 46 or reverses.

The question “How long will this turbine oil last?” should be answered with the sound engineering response of “it depends.”

Turbine oil suppliers can give fairly wide-ranging estimates, say 5 to 15 years, in gas turbine applications. Any attempt to create a more exact estimate requires consideration of so many variables that it becomes somewhat useless. Water, heat, contamination, operating hours and maintenance practices will have a significant impact on turbine oil longevity.

There is no denying that properly tested and maintained, higher quality turbine oils will provide longer life than poorly tested and maintained, lower quality products. Following is a discussion of new turbine oil performance characteristics that will promote longer, trouble-free service.

More than 100 tons of steel, rotating at 3600 rpm, is supported by plain bearings on a cushion of oil that is thinner than a human hair. In power plants around the world, the same fluid dynamics take place day-in and day-out without much notice.

Lost revenue at seasonal peaks can be counted in millions of dollars. An average utility sells electricity for about $50/MW hr during nonpeak periods, and as much as $1,000/MW hr during peak periods. Poor selection and maintenance of turbine oil can result in production losses exceeding $500,000 per day.

When selecting a turbine oil for steam, gas, hydro and aero-derivative turbines, oil supplier services and commitment to the customer should be evaluated as part of

Turbine and industrial oils are closely related. Many energy (  oil & gas sections) or people ( jet airplane) transferring devices are made by turbine machines and therefore the role of turbine oil in industry is of particular importance and also industrial oils have conquered an important part of the world lubricant market.

A good practice for turbine oil performance documentation is to take a 1-gallon sample from the supply tank and then a second gallon sample from the turbine reservoir after 24 hours of operation.


The recommended testing is consistent with turbine oil condition assessment testing: VISCOSITY ASTM D445  ,  RPVOT ASTM D2272 , WATER BY KARL FISCHER TITRATION ASTM D1744 , ACID NUMBER  ASTM D664 , ISO CLEANLINES CODE 4406 , RUST ASTM D664A , DEMOLSIBILITY ASTM D1401 , FOAM ASTM D892 , ICP METALS
