Tube Expanders
Simultaneous expansion and bead forming for firetube boiler applications.
Elliott's 4480 Series Single Roll Beading Expanders expand the tube into the tube sheet while forming a bead at the end of the tube — a requirement in many firetube boiler applications.
- Tube Size: 1.500" – 3.000" (38.1 – 76.2mm) OD
- Roll Type: Roll Beading
- Application: Firetube Boiler
“Best beading expander we've used. Clean bead, no second pass needed.”
