114 Series Flaring Tube Expanders
Uses:
The 114 series flaring tube expanders cover tubes from 2.0″ OD to 4-1/2″ OD. Used in fire tube boilers and air heaters when flaring tubes to 40 degrees. Fitted with self-contained rollers within the cage. This enables the expander to reach into confined spaces. For instance, by placing the cage into the tube before inserting the mandrel. Therefore, these are the ideal expanders to use in mud and steam drums when access is very limited. This is a general-purpose boiler tube expander used for expanding and flaring tubes. More information is available through the link below.
Advantages of the 114 Series Flaring Tube Expanders:
Insertion of the cage into the tube is important in tight spaces. In other words, this is only possible without the mandrel. Besides this is achievable by the rolls being self contained. Overlapping rollers prevent ridging of the tube giving a 40-degree flare.
Tube and Sheet Sizes:
- 2.0″-4.1/2″ OD.
- Tube Sheet Range 1/2″-2.5/8″.
- 3/4″ Square mandrel drive.
- Consisting of 4 Straight rolls and 2 Flaring rolls.
- Powermaster Industrial Expanders are always complete with drum-type mandrels ready for work.

Tube Rolling Drives
Electric tube rolling drives are the muscle behind a tube rolling task. Whereas the reliability and performance of the Eibenstock rolling drive. You have years of research and development built into every driver. Therefore, soft start and thermal overload are standard on all units.
Connection to the driver is via a Morse Taper #3. Furthermore, the high torque these units produce, commands a slow start. A mechanical clutch protects the two geared and reversible motors. This also prevents injury or damage to operators and attached tooling.
