PREDICTING BELLOWS SAFE LIFE BY ACOUSTIC EMISSION METHOD

The authors describe how acoustic emission diagnostics can be used to ascertain the status of power plant elements during service and without dismantling of the equipment. They particularly focus on the application of the method to multilayer metal bellows (MMB), which are airtight fittings widely used in power systems. These fittings operate at high pressures and temperatures in the corrosive environment of the working medium and are subjected to cyclic mechanical loads. The acoustic emissions method is shown to be promising in predicting the safe life of MMBs during their manufacture and in monitoring their residual service life.
