The URD® (Uniform Rigid Design) stand concept from SMS group is a key element in ERW tube mills, especially in the fin‑pass and squeeze sections. Its closed frame plate design provides exceptional rigidity and dimensional stability. Rolling forces are absorbed uniformly in both vertical and horizontal directions, eliminating the need for roll position readjustment. This ensures consistently high product quality and excellent dimensional accuracy. Compared with conventional stands, URD® stands offer higher reliability, improved process stability, and reduced setup times. Combined with innovative quick‑change systems, they enable fast product changes, high productivity, and safe, efficient operation in modern ERW tube production.
