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.
