Working principle and application of stainless steel oil storage tank

The combined long-term corrosion protection technology of coating protection and sacrificial anode protection is a highly effective method for preventing corrosion in oil and field storage tanks, as well as sewage tanks. This approach is not only efficient but also cost-effective, requiring minimal investment while significantly extending the service life of the equipment. Due to its practicality and benefits, it is highly suitable for widespread adoption and application.

**Oil Storage Tanks**

The fireproof vacuum pressure safety cap for oil storage tanks provides energy-saving, environmentally friendly, and fire-resistant advantages. This advanced safety device is installed on the pressure equalization port of oil storage tanks and consists of a housing with an outlet valve and an inlet valve. During tank filling, the outlet valve opens to release air, while during discharging, the inlet valve opens to allow ambient air in, maintaining pressure balance. When the tank is idle, both valves close simultaneously, isolating the tank from external factors and preventing the escape of gaseous oil or the entry of external fire sources.

The oil surface conditions in tanks vary under different circumstances. A functional relationship between oil volume, oil level, longitudinal tilt angle, and lateral deflection angle is established using the least square method and MATLAB software. The calibration of the tank capacity table after displacement is also provided. The model is validated using sampled data to ensure accuracy.
