5 Roller Tube Expanders

S-11

S-9 Boiler Thick Drum Tube Expander_edit

Full Description

The 5 Roller Tube Expander is intended for tube expansion applications where controlled rolling and a consistent finished surface are important. The legacy catalogue describes use with thin-wall tubes, including titanium tubes, and notes that the five-roller arrangement can provide more expansion coverage per rotation than a roller expander with fewer rollers. The product description also refers to roller burnishing, a process used to improve surface finish through controlled contact. Actual performance depends on tool configuration, material, lubrication, and operating parameters.

Key Features

Five-roller arrangement; intended for thin-wall tube applications; described for condenser and titanium tubes; supports controlled expansion; roller-burnishing applications may be available depending on configuration.
