API 650 welded aluminum storage tanks service conditions
In API 650 oil storage tank, when the mixing ratio of combustible medium and air reaches a certain limit, it is easy to cause explosion. Therefore, it is necessary to add API 650 welded aluminum storage tanks external floating roof to open cylindrical steel API 650 welded aluminum storage tanks tank. At present, the external floating roof is most suitable for large-scale API 650 oil storage tank in China, ranging from 20000, 30000, 50000 cubic meters to 100000 cubic meters.
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 welded aluminum storage tanks, Oil tank is a large-scale storage equipment used to store oil materials. Usually, the service life of API 650 welded aluminum storage tanks is related to the actual working conditions. The design service life of most oil tanks is 20 years, and some of them are 10-15 years. Generally, none of them is less than 10 years. However, the design service life of API 650 welded aluminum storage tanks is on the one hand, which is an ideal state, but there are many objective factors in the actual process, it is impossible to achieve the designed service life. How to effectively increase the service life of API 650 welded aluminum storage tanks?
