API 650 open top welded storage tanks floating suction line
Lateral braces between outer bay rafters must be provided if asymmetrical structural shapes are used for rafters and if the API 650 open top welded storage tanks API 650 tanks are located in areas subject to earthquakes. The bracing must be adequately sized for the seismic zone specified.
During heavy rain, closely observe the change of the water level in the storage area of the API 650 open top welded storage tanks. If the water level rises to the dangerous range, drain the water immediately. There are more thunderstorms in heavy rain, and lightning protection devices should be installed in the API 650 open top welded storage tanks area to avoid lightning accidents. Observe the groundwater level of the API 650 open top welded storage tanks area at any time, clean and dredge the drainage ditch in time to ensure unobstructed drainage, and prevent the bottom of the API 650 open top welded storage tanks from leaking and rusting due to untimely drainage.
Preheating should be performed by heating and maintaining this heat in appreciable lengths of the joint to be welded, preferably using a strip burner with a mild flame rather than a harsh flame such as that from a cutting torch. Electrical strip heaters are available and have been found to be satisfactory. The preheat of 300°F should be checked with a temperature-sensitive crayon, or similarly accurate means, so that the steel 4 in. (or four times the API 650 open top welded storage tanks plate thickness, whichever is greater) on each side of the joint will be maintained at the minimum preheat temperature. Ring burners or heaters are recommended for nozzle and manway welds. At no time during the welding should the base metal fall below a temperature of 300°F.
