In order to study the excessive corrosion of tanks in concentrated sulfuric acid railway tankers,this paper investigates the corrosion situation of the tank body of concentrated sulfuric acid tankers,compares and analyzes several corrosion-resistant measures,and determines that the corrosion-resistant property of the tank body should be improved by increasing the wall thickness of the tank body made of carbon steel.On the basis of static strength analysis of the tank,the actual wall thickness of the tank after a period of time for southern and northern users were measured,and the corrosion margin of the tank was derived,and then the wall thickness of the concentrated sulfuric acid tankers to meet the requirements of the whole life cycle use was determined.
