Elastic displacements of API standard 650 aboveground petroleum storage tanks

Deformation of the welding seam of the API standard 650 aboveground petroleum storage tanks is a common quality problem during the actual use of the API standard 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 standard 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.

Cylindrical Oil Storage Tanks Discharge Pipes
When a discharge pipe is used on the outlet side of such relieving devices, its area shall be not less than the area of the valve outlet, or if a single pipe provides for discharge from several relief devices, its area shall be not less than the aggregate area of the valve outlets. The API standard 650 aboveground petroleum storage tanks discharge pipe shall be fitted with an open drain to prevent water or other liquids from lodging in the discharge side of the valves.
Discharge pipes shall be supported so that no undue stress is placed on the valve body. Open discharges shall be placed and oriented so that the outflow is directed away from the tank and will not create a hazard over walkways, stairways, or operating platforms.

Since the foundation of the company, the Spring Festival Gala is an annual activity held at the end of the year. Now it is a part of the BBN company culture to enrich the employee's life.

There are opening ceremony, leader's speech, BBN steel performance, awards for outstanding employees, lucky draw, party game, curtain call, company group photo, annual Gala dinner and other links.

Determination of API 650 oil tank container: The total volume should be determined according to factors such as transportation mode and API standard 650 aboveground petroleum storage tanks fuel supply cycle. For train and ship transportation, the maximum consumption is not less than 20-30 days; the maximum consumption for automobile transportation is not less than 5-10 days.
