This paper is about structural analysis of ball valve for controling cryogenic LNG’s flow or stop in normal temperature. The used valve is demanded safety resist inner pressure and temperature variation cause it uses in cryogenic, high pressure surrounding. This study evaluates for safety resist inner pressure and temperature variation by heat transfer analysis in cryogenic surrounding, heat stress analysis in temperature variation and deformation analysis in high pressure.
