Insulated mounting method for combined supports of A-type independent liquid cargo tank

Abstract

The invention provides an insulated mounting method for combined supports of an A-type independent liquid cargo tank. The combined supports comprise rib plates, mounting panels, stow-wood grooves and stow-woods. The insulated mounting mainly comprises: using foaming materials to protect each combined support, and preventing heat loss caused by heat transfer between metals. Main steps of the method comprise: surface cleaning for the liquid cargo tank and the combined supports, spraying of an anticorrosive coating, spraying of the foaming material, perfusion of the foaming material through die cavities, and spraying of a protective coating. Through the steps, the problem of inconvenience for insulated mounting of the combined supports can be effectively solved, and because the method is directed at a structure characteristic of the A-type independent liquid cargo tank and spraying of the foaming material and perfusion of the foaming material are adopted at the same time, the insulated effect can be effectively ensured, the tightness of insulated mounting can be guaranteed, and heat outside the liquid cargo tank is prevented from transferred into the liquid cargo tank.

Description

technical field [0001] The invention relates to an installation method for the insulation of a combined support 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 structure or spherical ...

AI Technical Summary

Problems solved by technology

The structures of these components are often of complex types and staggered structures, which are not only inconvenient to install, but also require high technical requirements, and are prone to omissions that cause overall defects of the hull. Therefore, how to better install insulation on these support components is a problem that those skilled in the art need to solve question
