10ft diameter API standard 650 open top welded storage tanks
API 650 petroleum storage tank body design is mainly the design of tank bottom, API standard 650 open top welded storage tanks tank top and tank wall, and the design of tank wall is particularly important. As the main pressure bearing part of API 650 petroleum storage tank, the tank wall bears loads including liquid pressure, wind pressure, seismic load, opening stress, etc. The calculation of such loads is explained in detail in various API standard 650 open top welded storage tanks storage tank design standards. But in addition, the API 650 petroleum storage tank wall also bears the push-pull force and torque of the connected pipeline.
Inspection of weld and micro crack of API standard 650 open top welded storage tanks: the inner and outer surface of API standard 650 open top welded storage tanks, weld and heat affected zone shall be observed by naked eyes first. 100% ultrasonic testing or 100% penetrant testing are carried out for butt welds of API standard 650 open top welded storage tanks. For the defects found by 100% magnetic particle inspection, dye detection, 100% ultrasonic inspection or 100% penetrant inspection, the radiographic inspection shall be used again to ensure the accuracy of the test results.
The pressed-steel, round manhole with a 20-in. inside diameter shown in Figure F-8 is located in API 620 crude oil tank solid plate in spherical portion of a torispherical roof on a cylindrical storage tank 72 ft in diameter. The internal pressure, Pg, on the underside of the roof is 15 lbf/in.2 gauge. The thickness, t, of the roof plate required by 5.10.3 for the spherical portion of the roof is 1/2 in., which is exactly the thickness provided. No corrosion allowance is required. The materials in the oil tank roof plates and manhole frame conform to ASTM A283 Grade C steel; the main joints in the roof are double-welded butt joints, spot radiographed in accordance with 7.16 and 7.17.
