  Features

FTE Series Expanders

  • Flip collar accommodates different tube sheet thicknesses
  • 3-roll design expands and seals tubes in round or oval tube sheet holes
  • Increased expansion range means less inventory and lower operating costs
  • Ball bearing thrust collar allows torque controlled tube rolling
  • Short mandrels for use in limited space applications

Airetool product engineers have designed an economical, yet durable Firetube boiler tube expander for non-flaring (FTE) applications with 3/8" to 1" thick tube sheets. This unique design increases the expansion range for a given expander and includes a metal roll retainer that keeps the rolls in the expander’s cage when the mandrel is removed. Mandrels are sold separately with choices based on application and space limitations.
