Use of steel oil tanks and service life of tanks

During the use of oil tanks, most of the oil tanks are used in harsh environments. When some oil tanks are used outdoors, it is inevitable to suffer from rain. This is easy to cause pollution of oil by water. The water in the oil is mostly mixed during transportation, loading and unloading, and storage. The long-term storage of the oil will also precipitate the water dissolved in the oil. In the long-term accumulation, an acidic layer will appear at the bottom of the tank. . Among all the oils that have deteriorated due to storage, most of the oils are unqualified due to the mixing of water.

Related requirements for oil storage of oil tanks The cleaning cycle of various oil tanks is: light oil and lubricating oil storage tanks are cleaned once every three years; heavy diesel oil storage tanks are cleaned once every two and a half years. The cleaning and regular inspection of the tank not only ensures that the oil is not contaminated, but also allows you to have an accurate grasp of the health of the tank and avoid further safety hazards. In addition to various mechanical impurities mixed into the oil, it will block the filter and the oil circuit, causing oil supply failure, and also increase the wear of the base member and even cause scratches on the friction Surface. The moisture mixed into the oil can corrode the machine (the water will block the oil when it freezes under low temperature conditions); the presence of moisture will cause some additives such as detergent dispersants, antioxidants, antiknock agents, etc. to decompose and precipitate. Failure; when moisture is present, the oxidation rate of the oil is accelerated, and the amount of gum formation is also increased. In addition, the acidic water layer deposited at the bottom of the tank accelerates the corrosion of the tank, causing the tank wall to thin or even leak.

Oils of different natures of oil tanks cannot be mixed, otherwise the quality of the oil will be degraded, which will seriously deteriorate the oil. Bite is a variety of high-grade oil products, containing a variety of special effects of additives, when mixed with oils with different system additives, it will affect the special performance, and even the additive precipitation deterioration. When oil drums, tank cars, oil tanks, oil tankers, etc. are modified from non-same oils, the containers should be thoroughly cleaned, brushed and dried to achieve no impurities, moisture, grease and fibers.
