API 650 mechanically-anchored flat-bottom tanks forgings
Deformation of the welding seam of the API 650 mechanically-anchored flat-bottom tanks is a common quality problem during the actual use of the API 650 mechanically-anchored flat-bottom 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 mechanically-anchored flat-bottom 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.
The API 650 mechanically-anchored flat-bottom 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.
