A283 grade C plates API Std 650 horizontal tank

Safety comparison between mechanical cleaning and manual cleaning of vertical storage tank, API Std 650 horizontal tank. Closed cleaning is adopted for mechanical cleaning. During the cleaning process, operators are not required to enter the tank. The inert gas space formed in the storage tank can prevent the occurrence of fire, explosion and other accidents. When the API Std 650 horizontal tank is manually cleaned, the operators should directly enter the tank for cleaning, threatening the health of employees, and there is no inert gas space in the tank, which is prone to fire and explosion accidents.

Aftershock Level Earthquake (ALE)
This design case shall be applicable only when regulations or project documents specifically require the tank system to be designed or evaluated for aftershocks.
If the outer tank is not designed as a secondary containment (i.e. it serves as vapor barrier and pressure boundary only and is not constructed of API 620 material suitable for the inner tank API Std 650 horizontal tank), then no design or evaluation for ALE is required by these provisions for the inner or outer tank.

Lateral braces between outer bay rafters must be provided if asymmetrical structural shapes are used for rafters and if the API Std 650 horizontal tank API 650 tanks are located in areas subject to earthquakes. The bracing must be adequately sized for the seismic zone specified.
