Modern industrial-scale pipe bending technologies

At one of the largest metallurgical enterprises in Ukraine — ArcelorMittal Kryvyi Rih — the Startec Holding team commissioned a modern CNC tube-bending machine. The equipment confidently handles massive pipes and forms complex spatial components without losing geometry. This is an example of a high-tech approach to metal bending. The control system with 11 axes provides synchronized operation of all movements: feeding the pipe forward and backward, moving up and down, rotation, mandrel positioning, and simultaneous operation of three tools with different radii. This combination makes it possible to perform complex three-dimensional bends without deformation, even when working with thick-walled pipes up to 115 mm in diameter.

The mandrel inserted inside the pipe prevents dents in the bending zone — this is critical for geometric accuracy and durability of finished parts. Thanks to the intelligent control system, the operator sees a real-time 3D model of the process on the CNC screen, can verify the sequence of operations, and make adjustments even before starting the work. Despite the technological complexity, Startec Holding specialists promptly carried out delivery, commissioning, and training of ArcelorMittal personnel.

The trust of companies such as ArcelorMittal confirms Startec Holding’s position as a reliable partner and one of the leading experts in the market of modern metalworking equipment.

Startec Holding implements similar solutions at enterprises where precision, repeatability, and technological reliability determine the outcome. The project for ArcelorMittal Kryvyi Rih is yet another example of how modern technologies strengthen Ukrainian industry, making production more efficient, precise, and globally competitive.
