Expansion joints have been installed on gas turbine exhaust ducts since they were first introduced for power generation applications. Expansion joints are required to isolate the delicately balanced turbine from the stresses induced by thermal movements and vibration within the duct system.
Recent developments in turbine technology have placed increasing demand on the expansion joint supplier to accommodate greater movements and ever higher temperatures. Though financial consideration is always a factor, reliability and trouble free service is always the ultimate goal for both the end user and the expansion joint supplier.
