API standard 650 mixed material tanks dead load

Safety comparison between mechanical cleaning and manual cleaning of vertical storage tank, API standard 650 mixed material tanks. Closed cleaning is adopted for mechanical cleaning. During the cleaning process, operators are not required to enter the tank. The inert gas space formed in the storage tank can prevent the occurrence of fire, explosion and other accidents. When the API standard 650 mixed material tanks is manually cleaned, the operators should directly enter the tank for cleaning, threatening the health of employees, and there is no inert gas space in the tank, which is prone to fire and explosion accidents.

Floating roof is the key component of floating roof API 650 storage tank, which can be divided into external floating roof and internal API standard 650 mixed material tanks floating roof. The internal floating roof has a fixed top cover above the floating roof, which can prevent the floating roof from being exposed to wind and rain, and ensure the quality of oil stored under API 650 storage tank.

A cylindrical nozzle with a 12-in. inside diameter is located in solid plate in the sidewall of a cylindrical storage tank 60 ft in diameter so that its axis lies in a horizontal plane and forms an angle of 55° with a perpendicular to the sidewall at the point of intersection, as shown in Figure F-7. The thickness of the API standard 650 mixed material tanks sidewall plate, tw, in this area is 5/8 in., and no corrosion allowance is required. The total internal pressure, Pl + Pg, at the center of the opening is 26.1 lbf/in.2 gauge.
