API 650 floating-roof tanks general requirements for delivery of plates

In the petrochemical industry and other industries, large vertical API 650 floating-roof tanks are often used to store various production raw materials. Usually, the medium with high melting point and easy to crystallize at room temperature can be exported and used after heating, which involves the heating of large vertical storage tanks. The heating system is an auxiliary facility for heating of large vertical storage tank. It is often necessary to design external heating coil or internal heating coil system.

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 650 floating-roof tanks), then no design or evaluation for ALE is required by these provisions for the inner or outer tank.

Before the start of erection, inspect each API 650 tank foundation to ensure that it is level and acceptable to receive Work. Remove temporary erection attachments welded to the interior or exterior of the API 650 floating-roof tanks shell or to the bottom by arc gouging, and grind weld area smooth.
