ERW welded tube plants

Offering all core machines for ERW (Electric Resistance Welding) lines, our products are especially well known for their process precision. The perfect combination of know-how, innovation, automation, and digitalization ensures the production of high-precision tubes, line pipes, casings, tubings, and drill pipes as well as structural tubes and pipes with round, square, and rectangular cross-sections. We accompany you during the whole process chain – from the raw material to strip preparation, forming, welding, and sizing, to the cutting and finishing of your end product.

These flexible plants cover product diameters up to 710 mm with wall thicknesses between 0.7 and 25.4 mm.

The URD^® (Uniform Rigid Design) principle is the SMS solution for fin-pass, squeeze, and sizing stands. The stands are characterized by their rigidity and stability with a direct impact on the product quality. Thanks to the special stand design using closed frames, the rolling forces are absorbed both vertically and horizontally; meaning, the roll setting positions do not need to be readjusted.

X-Pact^® Quicksetting enables the computer-controlled automatic adjustment of all essential dimensional settings. The system forms the core of an integrated concept that ensures the shortest possible changeover times for ERW tube welding lines, and thus increases productivity. At the same time, product quality can be reproduced and continuously improved by means of database-supported plant settings. The system fulfills the current requirements for high flexibility in production with ever-smaller batch sizes and wider production mixes.
