double-deck roof API 650 mechanically-anchored flat-bottom tanks
API 650 internal floating roof oil tank executive standard: domestic design standard: GB50341-2003 "Vertical cylindrical steel welded oil tank design code"; domestic construction standard: GB50128-2005 "vertical cylindrical steel welded oil tank" Construction and Acceptance Specification; API 650 mechanically-anchored flat-bottom tanks Foreign design standard: API650-2007 "Standard for Welded Steel Petroleum storage tanks."
Above the water level, all API 650 mechanically-anchored flat-bottom 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 hot weather in summer brings great security challenges to the vertical oil storage tanks, API 650 mechanically-anchored flat-bottom tanks standing outdoors. We must find some simple and effective methods to protect the API 650 mechanically-anchored flat-bottom tanks in order to make them safely spend the summer. As a API 650 mechanically-anchored flat-bottom tanks manufacturer, in order to reduce the direct sunlight rate of the vertical oil tank, reduce the temperature change of the oil tank, and reduce the evaporation loss of the oil tank, we usually adopt the measures of applying sunscreen paint and washing with warm water.
