Abstract

Since natural gas is mainly transported or supplied in a liquefied state under high pressure, BOG (boil off gas) is frequently generated due to the adiabatic relation outside the pipe. To reduce BOG, various studies are being conducted. Recently, vacuum-insulated pipes are mainly used. Thus, in this study, temperature distribution in a vacuum-insulated pipe was observed through thermal analysis with the pipe type and diameter as design parameters. Additionally, thermal analysis was verified through an experiment under the same condition. BOG was calculated based on numerical analysis verification results and the heat transfer performance was confirmed. In addition, the generated thermal stress and thermal deformation changes were observed by implementing the temperature distribution obtained through the thermal analysis in thermal-structure coupling analysis. Accordingly, the structural safety of a vacuum-insulated pipe was evaluated
