This paper introduces principle of vinyl ester resin (acrylic modified epoxy resin) to resist chemicals and heat and with overseas use examples, narrates that coatings from vinyl resin can solve the present problems in oil storage tank, improve the corrosion resistance level and will be the development trend of oil storage tank.

With the development of the China, there are many large oil storage tanks established these years.

The soil corrosion of the oil storage tanks in Kelamayi Petrochemical Plant was introduced.

Stress Analysis of Big Oil Tanks on Flexible Foundation;

For the operation of oil tank, although the relevent safety and technical conditions (codes and/or standards) are being perfected,some unsafe factors,like tank earthing device and tank accessaries (breathing valve/hydraulic safety valve,flame arrester)exist.

The corrosion at the external bottom of the large scale oil tank were happened frequently.

The steel plate for large oil storage tank has shorter development history,its microstructure and properties are demanded grindingly and affected by many factors,the compositions and production processes are controlled subtly,the difficulty of production technology is larger and the development and research in China are late.
