Future technology development trends of cryogenic storage tanks
Date: Sep 23, 2020
Cryogenic storage tanks are essential 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 increase in demand from petrochemical enterprises, the development of cryogenic storage tanks has been rapid, and many technologies have also been applied.
For example, breakthroughs have been made in submerged arc automatic horizontal welding technology. Single-wire submerged arc welding technology is basically mature, simple in operation, and stable in welding quality. It will play an important role in the welding of large cryogenic storage tanks. In the future, it is necessary to carry out research on double-wire or multi-wire submerged arc welding technology to further improve welding efficiency. 
The gas-electric vertical welding technology 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 technology, reducing engineering costs, and meeting the needs of storage tank construction. In addition, the structural transformation of the currently used gas-electric vertical welding machine should be solved, so that it can be applied to the storage tank upside-down construction process, and further improve the welding quality and construction speed of the vault storage tank, shorten the construction period, and improve economic benefits .
In short, in the cryogenic storage tank industry, large volume, localization, and automatic welding will be the future development direction. Nowadays, the construction of large foreign storage tanks has basically realized mechanized operation. To catch up with developed countries, China still has a long way to go. The important role played by cryogenic liquid storage tanks in the development of the national economy is irreplaceable.
