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.

Boiler Introduction | CleanBoiler.org

In watertube boilers, boiler water passes through the tubes while the exhaust gases remain in the shell side, passing over the tube surfaces. Since tubes can typically withstand higher internal pressure than the large chamber shell in a firetube, watertube boilers are used where high steam pressures (as high as 3,000 psi) are required.
