Boiler Tube Expander
CSB Series Expander
- ‘5 Roll’ design is used primarily for rolling thin walled tubes in sugar mill juice heaters, pans.
- ‘5 Roll’ give you a more concentric, uniform expansion vs. a ‘3 roll’ expander in thin tubes and reduces tube ‘spring back’ effect
- Use – For buttom plate tubes expansion in pans, juice heaters in sugar mills.
SB Series Boiler Tuber Expander
- ‘5 Roll’ design is used primarily for rolling thin walled tubes in sugar mill juice heaters, pans.
- ‘5 Roll’ give you a more concentric, uniform expansion vs. a ‘3 roll’ expander in thin tubes and reduces tube ‘spring back’ effect
- Use – For top plate tubes expansion in pans, juice heaters in sugar mills.
