Frangible roof API standard 650 flat-bottom oil storage tanks
The water dissolved in the oil will be separated out from the oil stored in the API standard 650 flat-bottom oil storage tanks for a long time, and the acidic water layer will appear at the bottom of the API standard 650 flat-bottom oil storage tanks for a long time, which will accelerate the corrosion of the API standard 650 flat-bottom oil storage tanks and cause the wall thinning and even leakage. With the increase of service life, the API standard 650 flat-bottom oil storage tanks must be inspected and cleaned regularly to check the hidden danger.
refrigerated tanks secondary components are those whose failure would not result in leakage of the liquid being stored. Secondary components also include those API standard 650 flat-bottom oil storage tanks components that are not in contact with the refrigerated liquid but are subject to the refrigerated temperature vapors and have a combined tensile and primary bending stress under design conditions that does not exceed 6000 lbf/in.2. Secondary components that could be designed within this reduced stress are roof plates, including roof manways and nozzles with their reinforcement, roof-supporting structural members, and shell stiffeners.
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 standard 650 flat-bottom oil 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 cultural construction must let the enterprise staff participate in the enterprise culture, in order to better carry on the effective dissemination enterprise idea, the sharing value system, such as the internal communication, the newspaper, the forum, the propaganda, the news announcement and so on.
