Flanging Iron and Steel Plates for Construction of Boilers

FLANGING IRON AND STEEL PLATES FOR CONSTRUCTION OF BOILERS Iron plates are more severely tested by flanging than by any other work done upon them. This is due to their fibrous nature, and great care is necessary to prevent breaking in the bend, if the corner is sharp.

Flanging Iron and Steel Plates for Construction of Boilers

As has been stated, steel requires uniform heating and moderate curves. Flanging is almost entirely done to-day by machines. After flanging, the steel should be annealed by heating the whole plate uniformly to a dull red heat, and allowing it to cool slowly.
