API 650 aboveground petroleum storage tanks manufacturer's standard drain

Deformation of the welding seam of the API 650 aboveground petroleum storage tanks is a common quality problem during the actual use of the API 650 aboveground petroleum storage 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 aboveground petroleum storage 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.Uplift on Foundation
For API Standard 620 tanks with an internal design pressure less than 1 lbf/in.2 gauge, the uplift shall be taken as the smaller of the maximum uplift values computed under the following conditions:
a)The internal design pressure times 1.5 plus the design wind load on the shell and roof.
b)The internal design pressure plus 0.25 lbf/in.2 gauge plus the design wind load on the shell and roof.Storage tanks API 650 aboveground petroleum storage tanks designed in accordance with the rules and guidelines of API 650 are called API 650 storage tanks. API 650 is a control rule for welded storage tanks that work normally in the normal pressure range.In 2019, through the concerted cooperation of the enterprise team, the sales volume has grown steadily, and the annual sales volume has exceeded 300 million yuan.
