IEC was contracted to replace an aging turbine exhaust expansion joint as an Engineering Procurement and Construction (EPC) Contractor. IEC specified and selected a proper expansion joint to fit between the turbine exhaust and HRSG inlet based on the turbine exhaust profile. In order to fit the new expansion joint properly, IEC engineered new exhaust liner plates to ensure the new expansion joint would fit adequately. The new expansion joint was installed, and the power plant was able to return to normal operations.
