Externally Pressurized Expansion Joints  
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.
SRV Vent Connectors  

SRV Vent Connectors are designed for installation on pressure vessel safety relief valve vent lines. These products are engineered to handle the turbulent and high velocity flow that is typical in relief valve venting systems. American BOA SRVs provide a completely closed venting system between the relief valve and the silencer. SRVs eliminate the risk of uncontrolled steam discharge typical of drip-pan installations. American BOA SRV Connectors provide an additional measure of safety to your SRV venting system.

BCT Flexible Bellows Connectors (pump connectors)  
BCT Bellows Connectors protect rotating equipment such as pumps and compressors, from stress, strain, and vibration, thereby helping to enhance the life expectancy of your equipment. American BOA pump connectors utilize multi-ply bellows design for superior vibration control and maximum noise reduction.
XP Expansion Compensators  
XP Compensators are used to absorb axial thermal growth of small diameter piping systems. Compensators use the concept of an externally pressurized bellows to handle relatively large axial movements while maintaining high pressure capacity, without the presence of squirm.
