Ee A Pe aS Se ORT Te Boiler Scale and Boiler Repairs It is totally impossible to overheat a clean plate or tube, for the furnace heat is immediately passed through the metal to the water. Scale, keeping the water away from the metal, prevents the proper absorption of heat and allows the metal to overheat. At 650° F. steel begins to lose its strength; at 1200° F. this loss is about 75% | The overheated plate yields to the steam pressure and bulges outward--Bagged sheets mean heavy repair bills. Whether a furnace collapses, whether a back-connection bu! ges, or some tubes are blistered and burned, is a mere matter of chance. You can gamble on the fact that scale-covered, overheated boiler plates will surely cost you hundreds of dollars in repairs---if nothing worse.
