Boiler Drum Tube Expanders

Our range of boiler thick drum tube expanders is designed to accomplish the inner or the first operation. These expanders are non flaring adjustable collar type which controls the length of expansion by threads, provided on the body for the final operation. Depending upon the thickness of tube sheet, flaring type tube expanders are expanded in several progressive operations when boiler drums are thicker than standard roll size.

The combination of these two expanders should fulfill the exact requirement of thicker tube sheet tube expansion by 1/4" or 5-6 mm overlap of rolls between progressive operation. Boiler expanders we offer are self-feeding, parallel rolling and for serving the purpose of expanding and flaring in one operation, expanders are used.
