Application:

Lanbo’s F-Series Tube Expanders are self-feeding, specifically made for use in firetube and watertube boilers as well superheater and evaporator tubes. In only one operation, these expanders roll tubes parallel and flare projecting tube ends at 15 ~20 degrees from the tool center line.

Features:

Our F-Series expanders are available for tubes of diameter from 25.4mm to 101.6mm. The F-Series expanders are available in standard 3-Roll-3-Flare.

Note:

* Please contact our technical sales experts if 4-Roll-2-Flare or 3-Roll-1-Flare configuration is needed for your application.

*** Hexagonal Connector is available upon request, please contact our technical sales experts.
