Design and construction of thermal insulation structure in large floating roof crude oil tank wall will directly affect normal operation,safety,energy conservation and economy of oil tank. Aiming at the engineering practice in 10×10 4 m 3 floatingroofoil tank design ofSichuan Petrochemical Project,proposed are key points for material selection and structure design of thermal insulation layer in tank wall and introduced are construction principles and methods of thermal insulation color steel tiles in key positions of tank wall. In this project,applied are color steel tile with hot- dip galvanized base plate and PVDF finishing paint in external protective layer of thermal insulation structure so as to assure normal operation,safety,energyconservation and economyofoil tank.
