Optimal roll alignment for fast rolling. Maximum roll to tube contact reducing spring back effect. Equal load distribution leading to extended expander life
CNC machined cages give Precision guiding to rolls during expansion.
One piece cons truc ted mandrel on all models mates with well contoured rolls to give un-bridged smooth expanded tube.
State of the art cryogenic and heat treatment facility guarantees best grain structure in both pre-machined and finished forms.
Dual purpose collars with reversible nose to expand tubes flush with tube sheet and tubes projecting from tube sheet.
Highest quality bearings eliminate heat due to friction
Double radius rolls for easy long reach step rolling, supplied standard on all models.
Use of high end solid modeling design and finite element analysis software optimize results and eliminate design & assembly flaws.
