Complete finishing lines

completed by bypass repair sections with manual and automatic grinding and final inspection. Reika GmbH & Co KG – Germany

REIKA’s NDT systems are used by producers of steel tubes and stainless steel tubes, and the lines are often directly linked to straightening lines, which can also be delivered by Reika. Complete finishing lines as turnkey solutions are Reika’s speciality. The testing lines can be equipped with electromagnetic and ultrasonic testing systems. Typical testing brands are GEIT and Foerster, but other brands can be integrated in the existing standard interfaces. According to the demand of the tube mill, the adequate electronic devices can be chosen and integrated in the workflow. Before testing tubes, it is usual for loose scale from straightening and chips remaining after cutting to be removed. The tubes are transported individually with high speed into the multi-testing NDT-section. The lines are able to run up to at 5m/s throughput rate for eddy current testing only. The testing mode can be selected for continuous end-to- end testing in case of ultrasonic testing,

therefore the length of the untested ends is minimised. In front of the NDT- bench, a rotary wet brushing device can be installed. Two planetary driven steel brushes rotate around the axially transported tube, cleaning the surface of loose scale and dirt. Wear of the rotating probes and pollution of the water circuit are reduced, and ‘false defects’ with second testing can be reduced by 80%. The high precision concentric driving units and the complete transport mechanics are set-up within two minutes. The tube guiding precision of the constant centre drivers is proved by the high testing repeatability during the tube calibration mode. Tube eccentricity and orientation of the tube in the probe can be neglected, because the distance of the testing probe and the outer tube surface is almost constant along the circumference. Start-up of the complete lines can be executed within four weeks. Control interface to HOST computer systems are available for production reports and line status reports. The lines can be
