Tube Expanders
One-pass expansion and flaring for superheater and watertube boiler applications.
Elliott's 900 Series Flaring Boiler Expanders are self-feeding tools specifically made for superheaters in watertube boilers and evaporator tubes. In a single operation they roll tubes parallel and flare the projecting tube end at 15 degrees from the tool center line.
- Tube Size: 0.620" – 1.500" (15.4 – 38.1mm) OD
- Roll Type: Flaring
- Flare Angle: 15° from tool center line
- Application: Superheaters, Watertube Boilers, Evaporator Tubes
“The 900 Series cut our boiler retube time in half. Self-feeding makes a huge difference.”
