EN S355J0 plates API Std 650 SUG I tanks

This specification, in conjunction with API 650 Standard, prescribes minimum standards for the API Std 650 SUG I tanks design, supply, fabrication, erection, and testing of field erected welded steel storage tanks complete with accessories as specified herein and as shown on attached Datasheets and/or Drawings.

The API Std 650 SUG I tanks outer wall shall be designed for the purging and operating pressure of the space between the inner and outer tank shells and for the loading from the insulation, the pressure of wind forces, and the roof loading.
The outer tank bottom, shell, and roof shall have a minimum nominal thickness of 3/16 in. (7.65 lbf/ft2) and shall conform to the material requirements of Q.2.3.

Deformation of the welding seam of the API Std 650 SUG I tanks is a common quality problem during the actual use of the API Std 650 SUG I 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 Std 650 SUG I 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.
