Quality inspection of API 650 aboveground oil storage tanks

The structure of the API 650 aboveground oil storage tanks foundation mainly includes the insulating anticorrosion layer on the top surface of the foundation, the tank wall support, the edge retaining structure, the sand cushion, the oil and water barrier, the detection signal tube and other structures. The construction materials and requirements of each basic structure of the storage tank are different. After the structure of the API 650 aboveground oil storage tanks foundation is built in accordance with the construction requirements, the settlement of the storage tank foundation needs to be observed, and the uneven settlement value of the storage tank foundation should be within the allowable safety range.

Vertical Storage Tanks Security against Damage
The assemblies of relieving devices shall be secured against damage in service, the effects of storms, or mishandling. Access ladders and platforms that meet API 650 aboveground oil storage tanks plant safety rules are suggested.
Vacuum-relieving Devices
A vacuum-relieving device, when used, shall be as direct in inflow as possible with no pockets where moisture can collect, and it shall have no piping except a weather hood ahead of the inlet. An adequate vacuum-air inlet shall also be provided.

Before pressure testing, thoroughly flush the API 650 tank floating roof primary drain hose system. Supply API 650 aboveground oil storage tanks blind flanges, gaskets, and bolting (for other types of blanking covers as may be required) necessary for testing.
