The different qualities of bent tubes

2D, 3D bending

The rolling of tubes with large bending radius is carried out on a bending machine with 3 rollers.
The 3D bending involves the cold bending, hollow by winding and with a mandrel.

Spiral tubes

The precision necking is made on a 6-pass horizontal press with turning punches.

Bent tubes with shaped ends

Possibility of shaped ends : flared, reduced, flange
Possibility of nozzle ends : crimped, brazed or welded
