ESCO Millhog Tube Expanders

A new series of boiler tube expander kits that are used to create a mechanical seal for precisely sealing tubes to tube sheets is being introduced for sale or rental from ESCO Tool of Medfield, Massachusetts.

Esco Millhog Tube Expanders feature torque limits that can be preset from 25- to 325 ft.-lbs., depending upon the motor selected, for mechanically sealing tubes to tube sheets. Easy to operate, users simply attach the expander assembly to the air-powered rolling motor, then insert it into the tube and actuate the motor which pushes a mandrel and expands the tube. When the preset torque limit is reached, just reverse the motor and remove.

Suitable for any type of tube material, including stainless steel, Esco Millhog Tube Expander kits are available with flare-straight and straight expanders and adjustable collars.

Five different kits are offered to accommodate tubes from 1-1/4" to 4-1/4" O.D. and varying gauges for tube sheet thicknesses up to 4-3/8". Kits include a 6 ft hose whip with an in-line air filter, oiler, quick-disconnect couplings, and tools.
