Title:
HOLD PIPE USING SUPER HEAT INSULATION MATERIAL, AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/186180
Kind Code:
A1
Abstract:
A hold pipe using a super heat insulation material, comprising a conductive inner pipe, an anti-corrosion coating applied on the conductive inner pipe, a heat insulation layer formed by a super heat insulation material wound on the anti-corrosion coating, and a resin sealing layer covering the outside of the heat insulation layer. The hold pipe using a super heat insulation material is high in impact resistance, long in service life, and excellent in mechanical property and heat insulation performance. The used conductive inner pipe has excellent corrosion resistance against liquefied natural gas in the pipe, and compared with conventional steel pipes, the mass of the pipe is obviously reduced, so that the carrying and mounting costs are saved, and the efficiency is improved; a protective layer formed by the anti-corrosion coating and the resin sealing layer can prevent the conductive inner tube from being directly exposed in the environment due to long-time infiltration of seawater or accidental damage of an outer layer, thereby avoiding electrochemical corrosion and further improving corrosion resistance. In addition, a production method for the hold pipe using a super heat insulation material is provided.
