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. Cages are double tempered for optimum toughness at very high hardness.

One piece constructed mandrel on all models mates with well contoured rolls to give un-briged smooth expanded tube.

State of the art cryogenic and heat treatment facility guarantees best grain structure in both pre-machined and finished forms.

All components subjected to specific tests. Expander assembly is tested for optimum rolling, expansion and reversing speeds.

In operation, the initial positioning of the expander in the tube allows the self-feed rolls to draw the expander into the tube and to
engage the flaring rolls at proper point during the operation.

High carbon chromium tool steel for rolls ensures non deformability. Smoother contour and fine ground finishing gives longer life by withstanding operational jerks. Use of high end solid modeling design and finite element analysis software optimize results and eliminate design & assembly flaws.
