An I.D. clamping welding prep boiler tube repair tool that helps assure quality fit-up at biomass and fossil-fired plants by creating perfectly square end preps is available from Esco Tool of Holliston, Massachusetts.
The Esco Wart MILLHOG® Beveller mounts rigidly to the tube I.D., is self-centering, and provides torque-free operation with the ability to bevel, face, bore, and remove overlay simultaneously to create perfectly square end preps. This fully portable and easy to use tool cuts to a consistent height without cutting oils and should be the first step to a quality weld.
Only requiring 2.625″ W to fit between tubes for single tube maintenance in a boiler tube waterwall, the Esco Wart MILLHOG® Beveller is ideally suited for tube and pipe from 0.75″ to 4.5″ O.D. Featuring a self-centering draw rod assembly and attached clamping and ratchet feed wrenches, this robust tool has a sealed mandrel to keep debris out.
The Esco Wart MILLHOG® Beveler available for rent or purchase.
