Product Description

The Balance IX Twin is a relatively long stainless steel expansion joint with twin bellows construction and rotating flanges. It is used to accommodate axial movements and relatively large lateral misalignments in piping systems. Due to its double-ply bellows, this compensator is more flexible in comparison to similar single-ply compensators. The Balance IX Twin is supplied at pre-stressed length to reduce the reaction forces to the foundation in operating conditions (high temperature). The maximum operating temperature of the Balance IX is +550 °C, the maximum working pressure 2,5 bar (120 °C).
