Generally, to use bellows type expansion joint it is needed to install fixed point that receive thrust

        force of interal pressure, in case of large diameter and high pressure, it is difficult to install fixed

        point according to the place. you can use Pressure Balanced type expansion joint in this case

        and you can save expense of installation of fixed point.

        This type is classified into L type, S type and T type.

        - Design Pressure : Vaccum ~ 20kgf/cm2

        - Design Temperature : 300°C over
