Because of its special structure,the internal floating roof tank has become one of the most efficient methods to reduce the evaporation loss of oil products in petrochemical enterprises.However,it is easy to damage the internal floating disc and floating disc seal during use,which not only affects the production efficiency,but also may cause security risks.Based on the analysis of the reasons for the damage of the floating plate of the internal floating top tank and the comparison of several common forms of the floating plate seal,the paper summarizes the optimization process of the floating plate structure and the sealing of the floating plate of the internal floating top tank.
