API 650 self-anchored flat-bottom steel tanks shell

This standard only applies to API 650 storage tanks API 650 self-anchored flat-bottom steel tanks with uniform bottom support and non-refrigerated service storage tanks with a maximum design temperature of not more than 93 degrees Celsius (200 degrees Fahrenheit).

When the API 650 self-anchored flat-bottom steel tanks is welded, the weldment should be fixed rigidly. After welding, when the weldment is cooled to normal temperature, the rigid fixation can be removed, which can effectively prevent angular deformation and wave deformation. Although some measures have been taken, the welding deformation of API 650 self-anchored flat-bottom steel tanks is still unavoidable, so it is necessary to take corrective measures to compensate the deformation. Mechanical correction is to make the parts easy to deform in the welding process by mechanical or other rigid materials to produce simple deformation, so as to restore the state before welding.

API 620 Crude Oil Tank Pneumatic Pressure
An air pressure equal to 1.25 times the pressure for which the vapor space is designed shall be applied to the enclosed space above the water level. In the case of a double-wall tank with an open-top inner tank, where the air pressure acts against the outer tank and the inner tank is thus not stressed by the air pressure, the inner API 650 self-anchored flat-bottom steel tanks may be emptied of water before the pneumatic pressure test begins. The test pressure shall be held for 1 hour.
