Elliott's 900 Series Flaring Boiler Expanders are self-feeding, specifically made for use in superheaters in watertube boilers or evaporator tubes. In only one operation, these expanders roll tubes parallel and flare projecting tube ends at 15 degrees from the tool center line.

The expanding rolls will roll tubes �” (6.4mm) beyond the tube sheet thickness. The three flare rolls provide faster, more uniform flaring than other flaring expander models. The generous roll radius eliminates sharp offset within the tube. Additionally, the mandrel nut enables the assembly of the expander, mandrel, and drive as one unit.

Features & Benefits:

• 3 flare rolls for faster, more uniform flaring. Works evenly to the tube minimizing stress.
• Expander is self-feeding. In one operation expands and flares at 15 degrees.
• Specifically made for use in superheaters in watertube boilers or evaporator tubes. Readily available for evaporator tubes
