Product description
SB Series Tube Expanders for Sugar Mills
The SB series is a 5-roll tube expander for thin-walled tubes in sugar mills, especially for juice heaters, evaporator pans and similar equipment. The 5-roll design provides a more concentric, even expansion for thin tubes than a 3-roll expander and reduces the tube's spring-back effect.
Application in juice heaters and evaporator pans.
SB Series 5-roll tube expander.
Technical Benefits
The 5-roll design distributes forming forces more evenly around the tube circumference. This achieves more uniform and concentric expansion in thin-walled tubes. At the same time, the spring-back of the tube after expansion is reduced.

Note: Inch specifications are additionally provided with metric equivalents in the text and in important table cells. The model assignment A, B, and C refers to tube sheet thicknesses of 31.75 mm (1.25"), 38.1 mm (1.5"), and 50.8 mm (2.0").
What kind of work is the SB series suitable for?
The SB series is used for tube expansion in sugar factories when thin-walled tubes need to be uniformly expanded into top plates of juice heaters or evaporator pans. Due to its 5-roller design, the series is particularly suitable when quiet, concentric expansion and reduced tube springback are required.
