Tool creates perfectly square end preps
Don Horne
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, Mass.
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.
