Expansion Joints used in SM and FCC service are one of the most critical and complex types of expansion joints manufactured.
For this reason, the choice of manufacturer should be carefully considered.
KHI has many years of experience designing and manufacturing these expansion joints.
These expansion joints are exposed to high temperatures, high pressure, large movement conditions and aggressive media.
Great care and expertise is required in designing of the bellows and hardware to ensure that the units to perform well in service.
The use of redundant ply bellows on these expansion joint is widespread today.
Redundant ply designs offer safety and outage scheduling benefits.
The intent is to enable the unit to continue to operate until the next scheduled outage even after one ply has failed.
Various monitoring devices can be used from connecting a simple pressure gauge to electronic sensing devices.
