API 650 open-top tanks in SUG III
API 650 petroleum storage tanks use lightning protection, anti-static, and fire protection measures. The internal corrosion protection should be determined according to the API 650 open-top tanks storage medium, and the outer wall corrosion protection should be determined according to the soil quality of the buried tank.
As we know, the vertical metal tank, API 650 open-top tanks is welded by many components, and the welding quality of each component determines the later use effect of the API 650 open-top tanks. Professional API 650 open-top tanks manufacturers should have a set of professional skills in the welding process of API 650 open-top tanks. Key points for weld inspection of vertical metal tank, API 650 open-top 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.
The API 650 open-top tanks outer tank, which is not in contact with the vaporized liquefied gas, may be of single-welded lap or single-welded butt construction when the thickness does not exceed 3/8 in.; at any thickness, the API 620 oil tank outer tank may be of double- welded butt construction without necessarily having full fusion and penetration. Single-welded joints shall be welded from the outside to prevent corrosion and the entrance of moisture.
