API 650 larger diameter tanks non-removable legs

API 650 larger diameter tanks weld tightness test: remove dirt from the API 650 larger diameter tanks weld, apply white powder emulsion, spray kerosene on the other side of the weld after drying. Because of the strong penetration of kerosene, if kerosene is sprayed after 12 hours (under low temperature conditions, the time can be extended), if the surface of the welded seam coated with white emulsion has no spots, the welded seam meets the requirements.

Above the water level, all API 650 larger diameter tanks welded joints, all welds around openings, and all piping joints against which the pneumatic pressure is acting shall be checked with a solution film. A visual inspection may be substituted for the solution-film inspection if the welded joint has previously been checked with a vacuum box. The solution-film inspection shall still be made, above the water level, on all welds around openings, all piping joints, and the compression ring welds, including the attachment to the roof and shell.

The floating roof is the top cover floating on the liquid level, so the sealing performance of API 650 larger diameter 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 650 larger diameter 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.
