API Std 650 ambient temperature tanks roof support legs sleeves

In the event of continuous heavy rainfall, the inspection of the API Std 650 ambient temperature tanks 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 API Std 650 ambient temperature tanks from the oil unloading port and the oil measuring port, which will affect the oil quality.

Uplift on Foundation
For API Standard 620 tanks with an internal design pressure less than 1 lbf/in.2 gauge, the uplift shall be taken as the smaller of the maximum uplift values computed under the following conditions:
a)The internal design pressure times 1.5 plus the design wind load on the shell and roof.
b)The internal design pressure plus 0.25 lbf/in.2 gauge plus the design wind load on the shell and roof.

API 650 is the standard for welded tanks for oil storage. It specifies the API Std 650 ambient temperature tanks design, manufacturing, welding, inspection and installation requirements of oil tanks. API 650 is widely used in storage tanks with internal pressure less than or equal to 2.5 PSI.
