4-Roll Bending Machines
- Pipe Outside Diameter
- 15 m'ye kadar
- Wall Thickness
- Up to 150 mm
- Sheet Width (Pipe Length)
- 4,3 m'ye kadar
Features
- Fast and simple operation; plate positioning without crane handling is possible.
- Ideally suited for increased wall thicknesses with continuously high production output.
- Economic production of cones.
- Support yoke and supporting beam can be retrofitted.
- Straight ends are reduced to a minimum, cutting calibration work considerably.
- Various diameters from a single top roll — fewer exchange rolls, higher productivity.
- Capacity: plate width up to 4,3 m, wall thickness up to 150 mm.

Machine concepts
On the basis of the following machine concepts we find the optimum solution for you:

- fast and simple operation
- plate positioning without crane handling is possible
- ideally suited for increased wall thicknesses with continuously high production output
- economic production of cones
- support yoke and supporting beam can be retrofitted

- support of the slim rolls during the pre-bending of extremely increased wall thicknesses
- straight ends are reduced to a minimum
- considerable reduction of calibration works
- various diameters can be produced using a single top roll, less exchange rolls and increased productivity
- can be submerged in the foundation completely

- prevents the collapsing of comparatively thin plates with large diameters during the bending process respectively prevents the influence of the weight of such pipes on the bending process
