Storage tanks are mainly used for gas and liquid storage in oil fields and chemical plants. By maintaining the stability of parameters such as liquid level and pressure, the safety and efficiency of the process system can be ensured. For flammable, explosive, toxic, and harmful liquids or gases, dedicated storage tanks are designed with sealing, anti-corrosion, and fire prevention measures to isolate hazardous materials from the outside world and reduce risks such as leaks and explosions. The storage tank can store emergency supplies for centralized management and bulk sales.
