The development trend of cryogenic tank in the future

Cryogenic tanks are indispensable and important basic equipment for petroleum, chemical, grain and oil, food, fire protection, transportation, metallurgy and other industries. Our economic life is always inseparable from large and small cryogenic storage tanks. In recent years, due to the further growth of demand from petrochemical companies, the development of low-temperature storage tanks has been rapid, and many technologies have also been applied.

For example, the submerged arc automatic transverse welding technology has made breakthrough progress. The single-wire submerged arc welding technology has been basically mature, the operation is simple, and the welding quality is stable. It will play an important role in the welding of large cryogenic liquid storage tanks. In the future, research on double-wire or multi-wire submerged arc transverse welding technology will be carried out to further improve welding efficiency. The gas-electricity vertical welding technology used for longitudinal seam welding of storage tanks should be researched and developed to achieve localization, which is of great significance for breaking the monopoly of foreign technologies, reducing engineering costs, and meeting the needs of storage tank construction. In addition, the structural transformation of the welding machine currently used for gas-electricity vertical welding should be solved so that it can be applied to the inverted construction process of the storage tank, further improve the welding quality and construction speed of the vaulted storage tank, shorten the construction period, and increase economic benefits .

In short, in the cryogenic storage tank industry, large volume, localization, and automatic welding will be the future development direction. Today, the construction of large storage tanks abroad has basically achieved mechanized operation. The important role played by low-temperature storage tanks in the development of the national economy is irreplaceable.
