Abstract : An interesting case of marine boiler tube failure is described. As a result of local overheating, a ballooning burst occurred in a boiler tube. Evidence showed that a temperature of over 1600/degree/F (87/degree/C) had been reached before rupture. The presence of a thin film of copper arising from the auxiliary equipments of the boiler, caused pittings in the metal. failure was thus attributed to local overheating accelerated by an inner deposit of heat insulating scale.
