DIAMETER AND OUT-OF-ROUNDNESS MEASUREMENT ON TUBES.

Online measurement in a pilger mill at Vallourec & Mannesmann Tubes Deutschland GmbH

The works Rath operate one of the largest Pilger mills in the world. The mill produces tubes up to 660 mm outer diameter with wall thickness up to 100 mm.

The TDMS System (Tube Diameter Measuring System) measures the tube diameter after the roll stand online in two axes with a CCD line scan camera with backlighting.

The online measurement enables the operators to react immediately to changes in the process and to actively counter steer. The rolling process can be corrected before further tubes are rolled out of tolerance
