  • The change of state during and after water pressure proof test was monitored by strain gauges and acoustic emission. Residual stresses were measured by hole drilling method in critical zones of boiler drum and damaged tubes. In this way, initial (nil) stress state was established before placing the boiler into service. The initial level of residual stresses had reduced to after pressure testing, as a consequence of stress redistribution. Stresses calculated based on measured strains are elastic… CONTINUE READING
