Guide to expansion joints in gas-turbine exhausts
A
James Walker Townson product story
Edited by the Engineeringtalk editorial team
Mar 31, 2009
James Walker Townson has issued a white paper outlining the factors involved in choosing, installing and maintaining expansion joints in gas-turbine exhaust systems.
Expansion joints isolate the turbine from the stresses induced by thermal movements and vibration in the duct system.
Failure of these parts can result in the whole system shutting down.
Continual developments in turbine technology and demands for higher performance are placing demands on expansion joints to accommodate greater movement and even higher temperatures.
The guide covers topics such as frame design, overheating, joint materials, installation, noise, water washing and maintenance.
