A285C plates API standard 650 flat-bottom oil storage tanks
The floating roof is the top cover floating on the liquid level, so the sealing performance of API standard 650 flat-bottom oil storage tanks API 650 oil storage tank is very important. The floating plate mainly adopts elastic packing, and at the same time, it is compressed with the wall of API 650 oil storage tank with pressure strip around, and fixed with the floating plate with bolts. After the API standard 650 flat-bottom oil storage tanks floating plate is lowered to a certain position of about 1.8m, a prop will support the floating plate to keep it in position.
Testing the Outer Tank: While the test pressure is being held, all welded seams and connections in the outer shell and roof shall be thoroughly inspected with a solution film unless they were previously checked with a vacuum box. The API standard 650 flat-bottom oil storage tanks air pressure shall be released. Pressure relief and vacuum relief valves shall be checked by applying the design gas pressure to the outer tank, followed by evacuation of the outer space to the vacuum setting of the relief valve.
Large-scale vertical API standard 650 flat-bottom oil storage tanks mostly use internal tank bottom heating coils to heat the medium stored in the storage tanks. The heating coils are mostly smooth tube structures arranged in an annular circle along the bottom of the API standard 650 flat-bottom oil storage tanks. Commonly used heating methods include hot oil circulation heating method and hot water steam circulation heating method. The hot oil circulation heating method is to continuously extract part of the liquid medium from the storage tank, and then return it to the container to mix with the medium in the tank after heating, and the heat is quickly transferred through mechanical stirring.
