The invention provides an installation method for the insulation of the anti-floating device at the corner of a type A independent liquid cargo tank. The anti-floating device at the corner includes ribs, installation panels, skid grooves and skids. Foaming material protects each corner anti-float device to prevent heat loss caused by heat transfer between metals. The main steps of the present invention include surface cleaning of liquid cargo tanks and corner anti-float devices, spraying anti-corrosion layer, spraying hair foam material, pour foam material through the mold cavity, and spray protective coating. The above steps can effectively solve the problem of inconvenient installation of the insulation of the anti-floating device at the corner, and because the present invention is aimed at the structural characteristics of the A-type independent liquid cargo tank, and adopts spraying foaming material and pouring foaming material at the same time, it can effectively ensure the insulation The effect is to ensure the tightness of the insulation installation and prevent the heat from the outside of the cargo tank from being transmitted into the interior of the cargo tank.
Description
technical field [0001] The invention relates to an installation method for insulation of an anti-floating device at the corner of an A-type independent liquid cargo tank. Background technique [0002] The liquefied gas carrier is a special ship used to transport low-temperature liquid cargo such as liquefied petroleum gas and liquefied natural gas. These liquid cargoes are loaded in the liquid cargo tank of the liquefied gas carrier. insulation. The main purpose of the insulation of the cargo tank is to prevent the external heat from entering the interior of the cargo tank and reduce the evaporation of the cargo. [0003] According to the type of liquid cargo loaded, the workplace and other aspects, the liquid cargo tanks on the liquefied gas ship are divided into three types: type A, type B and type C, among which type A independent liquid cargo tank is mainly a flat plate structure with complete secondary shielding; B Type C independent liquid cargo tank is flat structur...
