Pipelines must be laid to suit the terrain and change direction to accommodate obstacles or the route. Pipes with a corresponding bend are required for this purpose. Only in very special cases factory-fabricated pipe bends are used for this. Rather, it is customary to cold-bend straight pipes in accordance with the specifications. Our pipe bending machines cover pipes with outside diameters between 2″ and 64″.

All of our bending machines allow for use on different pipe sizes by using insert bending sets. The pipe size ranges of our machines are deliberately designed to overlap to allow the customer to select the machine best suited to his/her usual projects.

Our bending machines produce pipe bends with a minimum radius of 40 times the pipe diameter (40 x D) by means of uniform bending steps at a defined distance.

For pipe sizes between 2″ and 12″ we offer bending tables where the bending is carried out in horizontal direction by means of a single hydraulic cylinder.

Vertical bending machines are available from pipe size 6″. Each of these has several hydraulic function groups, the interaction of which generates bending of the pipe.

With Vietz bending machines, bending takes place with adjustable individual pressures per function group in a defined sequence of movements of the respective hydraulic cylinders. In this way, the machine can be ideally adjusted to the material properties and wall thicknesses of the pipes to be bent.

Vertical bending machines are available with standard insert sets for conventionally coated (PE, PP) pipes and with special bending sets with plastic strips, as used for thin-layer epoxy pipe coatings. From machine sizes 6″ – 24″ all bending machines are equipped with hydraulic connections for a mandrel, which supports the pipe wall from the inside during the bending process.


Small Bending Machines

Not every pipeline demands large pipe diameters. Vietz GmbH developed bending machines especially for the small pipe sizes from 2” to 24”. Through their small size and light weight they are perfectly suited for a time-saving operation.

Medium Bending Machines

The versions of the medium bending machines from Vietz each have four hydraulic function groups. For the bending process the bending bed is moved by two front and two centre cylinders.

Here we install our unique pressure sequence control for the bending process, which allows it to run in a more defined and controlled manner.

The machine has connections for a hydraulic mandrel, which the machine operator controls from the console on the operator platform.

​Large Bending Machines

The bending process on these machines also runs via our pressure sequence control, so that the movements of the components involved in the bending run one after the other and are optimally concerted.

The machine has connections for a hydraulic mandrel, which the machine operator controls from the console on the operator platform.

Each of our pipe bending machines can be used for a range of pipe sizes. For this purpose, the machine must be equipped with a bending set suitable for the pipe.
