Installation method of anti-roll support insulation at both ends of the top surface of type a independent liquid cargo tank

Abstract

The invention provides an installation method for insulating the anti-roll bearings at both ends of the top surface of an A-type independent liquid cargo tank. The installation method of the above insulation is mainly to use foaming materials to protect the anti-roll bearings at both ends of each top surface to prevent heat loss caused by heat transfer between metals. The main steps of the present invention include liquid cargo tanks and two top surfaces. Clean the surface of the end anti-roll support, spray the anti-corrosion layer, spray the first foam material, pour the second foam material through the mold cavity, and spray the protective coating. The above-mentioned steps can effectively solve the problem of inconvenient installation of the anti-roll bearing insulation at both ends of the top surface, and because the present invention is aimed at the structural characteristics of the A-type independent liquid cargo tank, spraying the first foaming material and pouring the second foaming material at the same time Therefore, it can effectively ensure the insulation effect, 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 the insulation of anti-rolling supports at both ends of the top surface 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 t...

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
