10ft diameter API Std 650 stainless and carbon steel tank

The reticulated API Std 650 stainless and carbon steel tank shell API 650 storage tank is an important large-span space structure with high safety. Generally, the large-scale API 650 storage tank with a diameter of 21-60 meters or a volume of more than 20000 cubic meters should adopt the reticulated shell technology, which has been widely promoted and adopted in the world and China's petrochemical industry for more than 30 years.

Deformation of the welding seam of the API Std 650 stainless and carbon steel tank is a common quality problem during the actual use of the API Std 650 stainless and carbon steel 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 Std 650 stainless and carbon steel 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.

In this project, an area of steel storage oil tank wall is constructed of ASTM A285, Grade C, steel plate that is 5/8-in. thick and has spot-radiographed, double-welded butt joints. The wall is subject to tension in a meridional direction and to compression in a latitudinal direction. The values of R1 and R2 at the point under consideration are 75 in. and 300 in. respectively. A corrosion allowance of 1/16 in. is required. The computed (meridional) tensile stress, stc, in the net thickness after deduction of the corrosion allowance is 6000 lbf/in.2.
