Expansion joints manufactured to withstand the exhaust stack’s corrosive environment
The exhaust stack is connected to the outlet of the HRSG with uninsulated ducting and an expansion joint. Despite the low temperatures (under 350°F - 400°F) and minimal movements, the expansion joint installed at the stack requires careful material selection, design construction, and installation to ensure reliable operation.
