SB and CSB Series - tube expanders used in sugar mills
Configuration: five Parallel rollers
Tube sizes covered: 1.1/2"OD up to 4.1/2"OD
The SB and CSB series covers tube sheets from 1.1/4" up to 2.0" and are manufactured to suit the distance from the top to the bottom tube sheet. This then allows the bottom tube sheet joint to be rolled from the top plate as access is always restricted to the bottom rolled joint.
5 roll design primarily used for rolling thin walled tube used in sugar mill juice heaters and pans.
5 rolls gives a more concentric, uniform expansion compared to a 3 roll system with thin tubes and reduces the tube spring back from the materials memory.
SB Series for top plate expansion.
CSB for bottom plate expansion rolled from the top.
