Esco Tool's Millhog Tube Expanders and Rolling Motors create steel-to-steel mechanical seals in boilers, heat exchangers and condensers
Esco Tool's air-powered tube expanders and rolling motors are designed for creating steel-to-steel mechanical seals in boilers, heat exchangers and condensers. Esco Millhog Tube Expanders and Rolling Motors feature torque control from 25 to 325 ft.-lbs. for tube expansion and wall reduction to create tube joints. Once the proper torque level is established, this setting can be retained so that each time the throttle is engaged, the tool will stall when it reaches the desired tube expansion.
Allowing operators to roll multiple tubes, Esco Millhog Tube Expanders and Rolling Motors are offered in five kits to accommodate tubes from 1 inch I.D. to 4-1/4 inches O.D. and 1 to 20 Ga wall thickness. Configurations include straight and right-angle rolling motors for straight and flare rolls.
