Gaskets play a crucial role in preventing leakage and seepage when they are inserted and bolted into the flange joints of piping systems, such as those in shipbuilding, offshore plants, and marine engines. The application of conventional gaskets in pipelines can lead to galvanic corrosion between dissimilar materials over time, which can result in leakage of high-temperature and high-pressure fluids due to corrosion. This increases the likelihood of secondary accidents. In recent years, the demand for insulation gaskets to prevent galvanic corrosion has increased. The ability of insulation gaskets to prevent corrosion varies depending on their insulation performance. In this study, the structures and materials of the most widely used insulation gaskets developed overseas were analyzed. Additionally, a new structure and material for insulation gaskets were proposed. Electromagnetic field analysis simulations were con-ducted by modeling the application of advanced products and proposed insulation gaskets. Furthermore, physical tests were performed by installing actual gaskets to confirm the extent of improvement in real insulation performance when applying advanced products and the proposed insulation gaskets.
