Bellows type expansion joint - In-line Type Pressure Balanced

In-line pressure balanced expansion joint is designed to absorb axial movement and/or lateral deflection while restraining the pressure thrust by means of tie devices interconnecting the line bellows with outboard compensating bellows also subjected to line pressure, Each bellows set is designed to absorb the axial movement and usually the line bellows will absorb the lateral deflection. This type of expansion joint is used in a straight run of piping.
