6061 aluminum pipe API 650 liquid-storage tanks

Tank cracks are common API 650 liquid-storage tanks defects, mainly including tank wall cracks, internal cracks, weld zone cracks. The reason for these defects may be that the defects not exceeding the standard existed in the early stage of API 650 liquid-storage tanks construction, which become obvious after the later use. Or in the process of using the API 650 liquid-storage tanks, the tank body material generated new defects due to corrosion, pressure, wear and other reasons, and tank cracks.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.API 650 internal floating roof API 650 liquid-storage tanks tank can be used to store gasoline, jet fuel and other volatile oil products, as well as aldehydes, alcohols (methanol, ethanol), ketones (acetone), benzene (benzene, toluene, xylene, styrene) and other liquid chemicals.We specialize in the production and sale of steel products.
