27m diameter API standard 650 unanchored flat-bottom tank
If additional requirements are met, higher internal pressures are allowed. API 650 only covers tanks that support the whole bottom evenly and API standard 650 unanchored flat-bottom tank tanks in non-refrigerated service that have a maximum design temperature of 200 degrees F. It requires that you have a minimum material thickness of 3/16 inch.
Atmospheric API standard 650 unanchored flat-bottom tank inspection includes annual inspection and comprehensive inspection. Annual inspection is an inspection during operation to ensure the safety of atmospheric storage tanks during the overhaul period, at least once a year. Comprehensive inspection is a more comprehensive inspection of atmospheric storage tanks according to a certain inspection cycle. The inspection content of metal atmospheric API standard 650 unanchored flat-bottom tank includes the safety management of the storage tank, the inspection of the tank body and its operating conditions, etc.
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%.
