Large oil tanks are the trend of future development. With the rapid development of China's economy, the development of China's petrochemical industry, and the demand for national strategic development, the demand for oil tanks is becoming increasingly evident. China has very few land resources, and the prices of construction land have continued to rise in recent years. The use of small oil tanks cannot meet the demand for large amounts of inventory.

Therefore, the development of large oil tanks is imperative. Large equipment has the advantages of material saving, small footprint, convenient operation and management, and low investment, which is what customers need.

In recent years, China's petroleum industry has developed rapidly, with very cautious requirements for quality, bringing in a large number of customer resources. Therefore, there are requirements for the purity and quality of petroleum, and the use of large oil tanks to ensure better petroleum quality. In addition, the high requirements for fuel tank materials have not made good products more "colorful" and "seamless".
