ASTM A992 structural shapes API standard 650 cylindrical liquid-storage tank

Deformation of the welding seam of the API standard 650 cylindrical liquid-storage tank is a common quality problem during the actual use of the API standard 650 cylindrical liquid-storage tank, which easily causes the tank body to leak and affects the safety of the oil storage tank. The welding seam deformation of the API standard 650 cylindrical liquid-storage tank 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.

For open top and fixed roof API 650 tanks, the net working capacity is the liquid volume contained between the minimum operating level (top of API 650 tanks API standard 650 cylindrical liquid-storage tank outlet connection) and the maximum operating level [limited to the bottom of overflow connection, 75 mm below foam chamber connection, or 150 mm below rim, whichever is greater.

If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
