Externally pressurized expansion joints are utilized to compensate for large axial expansion of long piping systems. American BOA externally pressurized expansion joints are designed such that fluid/steam pressure acts on the outside of the bellows in addition to the internal surface of the bellows. The stabilizing effect of this external pressure increases the bellows ability to absorb long axial movements without the existence of squirm. This feature makes the externally pressurized expansion joint the best solution for many situations involving extensive axial movement.
