ISO 630 grade E355 plates API 650 vertical welded storage tanks

Deformation of the welding seam of the API 650 vertical welded storage tanks is a common quality problem during the actual use of the API 650 vertical welded storage tanks, which easily causes the tank body to leak and affects the safety of the oil storage tank. The welding seam deformation of the API 650 vertical welded storage tanks is mainly caused by the lack of reserved welding seam gap and irregular operation. The oil storage tank has not reserved the corresponding weld gap, resulting in deeper root removal during the front welding activity. The heat output of the weld will increase under the influence of a long time, and the deformation of the weld will gradually become serious.

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