Tube Failures in High Pressure Boilers

Tube failure in high pressure boilers follow a normal bath tub curve, with higher rate during initial operation period, stabilizing to a lower rate during the normal operating period and again increasing as the boilers age and cross ten to fifteen years of operation. During this period the boiler pressure parts are evaluated for their remaining
