How to test deck seams of API 650 insulated tanks

Determination of API 650 oil tank container: The total volume should be determined according to factors such as transportation mode and API 650 insulated tanks fuel supply cycle. For train and ship transportation, the maximum consumption is not less than 20-30 days; the maximum consumption for automobile transportation is not less than 5-10 days.

The main contents of safety inspection for atmospheric storage tank, API 650 insulated tanks are to see whether the tank foundation is sunk, whether the tank is corroded, whether there are cracks in the tank body and bottom, whether there is concave convex phenomenon on the top and wall of the tank, whether the accessories of the storage tank are in good condition, etc. After the API 650 insulated tanks safety inspection and detection, the defects found in the tank should be handled according to the inspection rules in time to ensure the normal and safe use of the storage tank in the later stage.

The opening pressure or vacuum of the pressure relief and API 650 insulated tanks vacuum relief valves shall be checked by pumping air above the water level and releasing the pressure and then partially withdrawing water from the tank. After the tank has been emptied of water and is at atmospheric pressure, the anchorage, if provided, shall be rechecked for tightness against the hold-down brackets. Air pressure, equal to the design pressure, shall be applied to the empty tank, and the anchorage, if provided, and the foundation shall be checked for uplift.
