A full line of air-powered tube expanders and rolling motors for creating steel-to-steel mechanical seals in boilers, heat exchangers and condensers is available for sale or rent. The Esco Millhog tube expanders and rolling motors feature precise torque control from 25 to 325 ft-lb for tube expansion and wall reduction, ensuring tight tube joints. Once the proper torque level is established, the setting can be retained so that each time the throttle is engaged, the tool will stall when it reaches the desired tube expansion. The tool allows operators to rapidly roll multiple tubes, and comes in five kits to accommodate tubes from 1-in. i.d. to 4.25-in. o.d., and wall thickness of 1 to 20 Ga. Configurations include straight and right-angle rolling motors for straight and flare rolls.
