API standard 650 low-alloy steel tanks overturning stability

The company has a group of mature steel plate production and processing line construction and production management experience. In addition, the company has professional and technical personnel. BBN steel is a modern enterprise integrating scientific research and development, production processing, sales and service. The company now has finance department, production department, sales team, technical department, quality control department, logistics department and after-sales service team. At the same time, it also adheres to international standards and adheres to the international line.

As we know, the vertical metal tank, API standard 650 low-alloy steel tanks is welded by many components, and the welding quality of each component determines the later use effect of the API standard 650 low-alloy steel tanks. Professional API standard 650 low-alloy steel tanks manufacturers should have a set of professional skills in the welding process of API standard 650 low-alloy steel tanks. Key points for weld inspection of vertical metal tank, API standard 650 low-alloy steel tanks:
1. It is strictly forbidden to paint the welds before passing the inspection.
2. Visual inspection shall be carried out for welds.
3. NDT shall be carried out on the weld.

Ultrasonic Examination of Butt-welds in Plates
Butt-welds in all tank wall courses subjected to a maximum actual operating membrane tensile stress, perpendicular to the welded joint, greater than 0.1 times the specified minimum tensile strength of the API standard 650 low-alloy steel tanks plate material shall be completely examined.
Butt-welds in API 620 oil tank wall courses subjected to maximum actual operating membrane tensile stress, perpendicular to the welded joint, less than or equal to 0.1 times the specified minimum tensile strength of plate material shall be spot examined in accordance with Figure Q-2.
