  Features

FTF Series Firetube Boiler Flaring Tube Expanders

  • 3-roll design expands and seals tubes in round or oval tube sheet holes
  • Offset flare rolls eliminate ridges produced by competitive models
  • Metal roll retainers keep the rolls in tool when mandrel is removed
  • Increased expansion range: Accommodates more tube sizes, reducing inventory cost
  • Thrust collar: Provides uniform flared tube ends
  • Short mandrel options for use in limited space applications

The FTF series expanders complement the FTE series boiler expanders but include tube flaring capabilities. This design incorporates a thrust collar for torque controlled tube rolling, roll retainers, and offset flare rolls.
