The OSI type gasket is manufactured by attaching metallic rings made of various metals in the inner and outer walls of the basic-type gasket. The inner wall does not deform even when it is over-compressed by the inner ring, and the outer ring can be easily assembled. It has an improved pressure resistance and the highest reliability. OSI is a typical type of spiral wound gasket that can be applied in environments of extreme cold, high temperature, and high pressure. It is used for many different purposes, including power-generation plants, shipyards, refineries, petrochemical plants, and other plants.
