An Economical, Durable Tool
Elliott’s 40 Series Straight Boiler Expanders are recommended for re-rolling leaky tube joints in Firetube boilers. Self-feeding, these expanders can be used by hand or powered by a rolling motor for fast tube rolling.
Guard Prong Accommodates Tube Projections
The guard prong is ½” (12.7mm) long, allowing you to roll boiler tubes with a projection, while also controlling the mandrel feed to prevent over-rolling.
Torque Controlled Tube Rolling
The bronze bearing between the expander’s frame and guard reduces friction and allows for torque controlled tube rolling.
Only for re-rolling leaky tube joints in firetube boilers.
