EFFICIENCY OF TREAD ALLOYS FOR VERTICAL STEEL TANKS

Abstract

The article discusses the use of various protector alloys made of magnesium and aluminum to protect vertical steel tanks when storing oil and oil products. Characteristics of protector alloys made of magnesium or aluminium and their alloys are shown. Data on the rate of selfdissolution of protector alloys depending on the degree of mineralization of bottom water are given. Gravimetric tests were used to calculate the mass index of the corrosion rate and electrochemical tests were used to calculate the efficiency of the anode current density. An empirical equation is shown by which the self-dissolution rate of protector alloys made of aluminum and magnesium alloys can be calculated, and empirical coefficients are given for the case of using protector alloys considered in the work. The obtained empirical dependence will make it possible to predict the rate of self-dissolution of aluminum and magnesium protector alloys. The efficiency of magnesium and aluminum protector alloys was analyzed and the dependence of the efficiency factor on the anode current density for magnesium and aluminum protector alloys was shown. Shows the effectiveness of using aluminum protector alloys to protect vertical steel tanks. It was concluded that the use of aluminum protector alloys is more efficient, since their efficiency is higher than that of magnesium alloys, this is clearly seen in the graph presented in the work on the dependence of the efficiency on the total mineralization of bottom water. The results of the work can be used in the design of protector protection for vertical steel tanks pre-designated for storage of oil and oil products containing produced water of various salinity.
