Non-contact dimension measurement in the pipe industry

ZUMBACH, Switzerland, offers a complete line of measuring and monitoring instruments. In the steel and metal industry, the company’s systems are used in the manufacture of hot and cold rolled products and in cold processes for semi-finished products. Typical areas of system useage are straightening, hot rolling mills for wire steel rod, profiles and seamless pipes, welded pipe manufacture, test stands (NDT), and cold processes such as peeling, grinding and polishing. The company’s Steelmaster gauges and systems are designed to fulfil market requirements such as closer tolerances, zero fault, 100 per cent quality control, higher productivity, faster start-up, less downtime and less manpower. The Steelmaster processor is the ‘brain’ of the system, as it processes the measuring data, communicates with the plant network and provides the operator with self-explanatory displays and key data. The process transparency is dramatically improved, especially if multiple measuring heads are installed. SMO oscillating gauges

for round and non-round products feature up to six measuring axes, seamless 360° coverage, no blind zones, and measurement independent of twist. With an increased number of axes, more data can be captured at the same time, and the measurement cycle per profile is shorter. SMO gauges can also be operated in static mode, in selectable orientation. SMS static gauges are suitable for round products, and feature up to six fixed axes, no moving parts, compact design, practically no maintenance, fast measuring rate (1,000/s in longitudinal direction), and short measuring distances. Advantages of the Steelmaster gauges include easy integration, dependable operation, up to 6,000 measurements per second (1,000 per scanner), distributed intelligence, one single (fibre optic) cable between LPO and CPO, compact industrial PC with highest working reliability, highly developed software, and sophisticated mechanics and protection system. ODAC® laser scanners with latest optical and laser technology are the ‘heart’ of

the Steelmaster gauges. Zumbach offers ODAC models with measuring fields from 15mm (0.59") to 500mm (19.68"), and larger models upon request. The scanners are accurate and permanently calibrated, with high resolution, high measuring rates (up to 1,000/s), and high immunity to dirt. This FPS method, based on special algorithms, generates a complete profile synthesis (contour). This profile makes it possible to derive data, such as out of round, reference centres and other key elements, used for the adjustment of the rolls. Oscillating SMO systems are able to capture more data, allowing for precise profile measurements. Even in the case of varying twist, or if the extreme points have not been captured by any scans, this method provides exact values of the minimum, the maximum, out of round condition and the derived data.
