API 650 closed top welded storage tanks fabrication requirements

,API 650 closed top welded storage tanks. Visual InspectionUpon completion of all the foregoing tests, the pressure in the tank shall be released and a thorough visual inspection shall be made of both the inside and outside of the tank, giving particular attention to all internal ties, braces, trusses, and their attachments to the walls of the tank. Anchors shall be checked for snug tightness and adjusted if required. Anchor threads shall be fouled by peening or tack welding to prevent loosening. In lieu of thread fouling, double nuts may be used.Rate of Water Filling and Water TemperatureThe rate at which water is introduced into a tank for a hydrostatic test shall not exceed 3 ft of depth per hour. The foundation, venting equipment, or other conditions may limit the water filling to a lower rate. Pressure shall not be applied above the surface of the water before the tank and its contents are at about the same temperature.The American standard API 650 design has been widely used.
