API standard 650 anchored liquid-storage tanks fabrication
In order to prevent the deformation of the bottom of metal vertical storage tank, API standard 650 anchored liquid-storage tanks during welding, the number of welders should be reasonably distributed. When welding metal vertical API standard 650 anchored liquid-storage tanks, personnel and welding position shall be reasonably allocated according to the actual situation of welding personnel, and random welding is not allowed.
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 standard 650 anchored liquid-storage tanks), then no design or evaluation for ALE is required by these provisions for the inner or outer tank.

API 650 is an American standard for welding flat bottom vertical storage tanks. This API standard 650 anchored liquid-storage tanks standard specifies requirements for the design, manufacturing, welding, inspection and installation of storage tanks. API 650 is widely used in storage tanks designed to withstand low internal pressures and used to store typical products such as API standard 650 anchored liquid-storage tanks crude oil, gasoline, chemicals and water. BBN has extensive experience in API 650 tanks, from +/- 500 cubic meters of tanks produced in the factory to +/- 15000 cubic meters of tanks produced on site
