The floating plate of the floating roof tank is a complex integrated structure, and must be designed to always float above the liquid level, so as to reduce the evaporation loss of the medium, protect the medium combustion area in the accidental situations such as fire, and consider the durability, safety, medium compatibility, daily operation adaptability and the like of the floating plate body.
The history of the domestic floating roof storage tank can be traced back to 70 years in the last century, and by the cooperation of units such as Beijing Petroleum institute and Oriental Red oil refinery, one 3000m3 gasoline vault tank of the Oriental Red oil refinery is transformed into an inner floating roof storage tank in 3 months in 1978, and a tray type design is adopted, so that the first inner floating roof storage tank in China is born. As a mountain-opening nose of a steel welding floating disc, the safety of the tray-type floating disc is poor, once liquid enters the upper part of the floating disc, the risk of overturning the whole tray exists, and therefore, a plurality of varieties appear on the basis of the tray-type floating disc, for example, the tray space is separated by using a partition plate, so that liquid inlet in a certain area above the tray body cannot be diffused to the whole tray of the open bin-type floating disc. However, the problem of the inability of such floating plates to provide positive buoyancy has been constant and has been quickly replaced by floating plate types having a complete floating chamber structure, such as steel welded single-plate, double-plate floating plates, etc. From the perspective of safety and environmental protection, the steel welded single-disc type floating disc and double-disc type floating disc are superior products. On one hand, the steel welding floating disc has the characteristics of full liquid connection and no splicing seam, and can better control the evaporation and discharge of a medium; on the other hand, the steel welded plate body has high strength, has natural advantages in the aspects of fire resistance and explosion resistance, can well protect the liquid level of a medium in an accident and avoid developing into a full-area fire.
The welded steel floating plate has an installation height during on-site manufacturing and installation, and needs to be manufactured at a specific height above a storage tank bottom plate, so that a clamping fixture is needed to support the lower part of the floating plate. The traditional mould adopts the section steel to carry out full-scale support, and at the inside on-the-spot preparation of storage tank, the preparation flow is complicated, loaded down with trivial details and preparation cycle length, and full-scale support uses the type steel material many, with high costs, and the preparation is accomplished the back mould top layer roughness poor.
