API 650 unanchored liquid-storage tanks formulas

,API 650 unanchored liquid-storage tanks., Oil tank is a large-scale storage equipment used to store oil materials. Usually, the service life of API 650 unanchored liquid-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 unanchored liquid-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 unanchored liquid-storage tanks?The refrigerated tank primary components shall also include those parts of a single-wall or an inner tank that are not in contact with the refrigerated liquid but are subject to the refrigerated temperature. Such API 650 unanchored liquid-storage tanks components include roof plates, roof manways and nozzles with their reinforcements, roof-supporting structural members, and shell stiffeners when the combined tensile and primary bending stresses in these components under design conditions are greater than 6000 lbf/in.2.All edges of the inner wall of the API 650 petroleum storage tank to be lined or coated must be rounded and flat to a minimum radius of 3mm. The API 650 unanchored liquid-storage tanks internal welding seam must be completely sealed welding, with a smooth surface and no air holes, air pockets and local protrusions. Remove welding spatter. As specified in API 650 petroleum storage tank design drawings, the seller must perform additional surface treatment.The 2019 Year of the Pig is the 70th anniversary of the founding of the People's Republic of China.
