The primary purpose of an expansion joint is to provide a point of flexibility in flue ducts and relieve stress caused by system movement.
The design parameters which influence the performance of any expansion joint and which must be defined for proper design analysis include:
- Design / Operating Temperature
- Design / Operating Pressure
- Flue Gas Composition
A properly designed expansion joint successfully accommodates operating factors that include:
- Absorption of Vibration or Shock
- Minor Misalignment of Ductwork
