Except as permitted by API standard 620 Q.8.6, the test shall be conducted after the entire tank is complete, before the insulation is applied. Except as limited by foundation or stress conditions, the test shall consist of filling the tank with water to the design liquid level and applying an overload air pressure of 1.25 times the pressure for which the vapor space is designed. The load on the supporting foundation shall preferably not exceed the established allowable bearing value for the tank site. Where a thorough evaluation of the foundation justifies a temporary increase, the established allowable bearing may be increased for the test condition, but the increase shall be not more than 25%.

The seismic effects on the tank wall of API 650 oil storage tank include the inertia moment generated by the weight of the API620 internal tank pressures tank and the hydrodynamic pressure of the reservoir, which can be divided into short period pulse pressure and long period fluid slopping convective pressure.

We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.

In the event of continuous heavy rainfall, the inspection of the API620 internal tank pressures farm should be strengthened to monitor and pay close attention to the soil moisture content of the tank farm in order to quickly take emergency measures. Check whether the seals of the oil unloading port and the oil measuring port are in good condition in time to prevent rainwater from leaking into the API620 internal tank pressures from the oil unloading port and the oil measuring port, which will affect the oil quality.
