A fixed ring of ultrasonic sensors mounted on the first calibrator reportedly allows much faster die centering and start-up of large pipe extrusion lines, drastically reducing scrap. Inoex GmbH in Germany (U.S. office in Lancaster, Pa.) developed the ultrasonic wall-thickness measuring device to allow operators to adjust die centering manually, using data taken close to the die as pipe production begins, instead of having to wait hours to measure wall thickness at the end of the pipe after the cooling tanks. Inoex has designed the pipe wallthickness optimization tool in six standard sizes for pipe ODs from 90 mm (four sensors) up to 2000 mm (24 sensors). (717) 672-0870 • www.inoex.com
