Best Practices For Expanding Water-Tube Boiler Tubes

Boiler expanders are designed with rolls sufficiently long to roll 1/4" to 3/8" beyond the sheet thickness. Boiler inspectors insist that tubes be rolled the full thickness plus a minimum of 3/16" beyond the sheet or drum thickness to a maximum 1/2". It's very common to use four or five different tools when repairing watertube boilers.
