Product Description

The Balance I with inner sleeve is a stainless steel expansion joint with carbon steel weld ends and a stainless steel inner sleeve. It is used to accommodate axial movements and relatively small lateral misalignments in piping systems with large diameters. Due to its double-ply bellows, this compensator is more flexible in comparison to similar single-ply compensators. The maximum operating temperature of the Balance I with inner sleeve is +550 °C, the maximum working pressure 2,5 bar (50 °C).
