Sikora at Tube China 2018 SIKORA AG is a manufacturer and supplier of advanced measuring, control, inspection and sorting technologies for the hose and tube, metal, wire and cable, optical fibre and plastics industries. At Tube China in Shanghai the company presented a broad portfolio of innovative systems for non-destructive quality control and process optimisation during production of metal tubes, pipes, strips and plates at its booth. over the entire circumference of the product. In addition, fast rotating tubes and pipes can be precisely measured. The radar measuring system requires no calibration and delivers continuously precise measuring values, which results in high reliability and availability for the user. Due to the narrow design, Radar Scan 6000 can easily be integrated into the production process. The technology

With the Radar Scan 6000, Sikora showcased a system for the online and contactless measurement of the diameter and ovality of metal tubes and pipes. The system is based on progressive, high-resolution radar technology and represents an innovative alternative to optical triangulation technology. In metal tube and pipe applications, the measurement is done simultaneously via transceivers from different directions over 360 degrees of the product circumference. The advantages of radar technology, compared to optical measurement methods, are that the measurement is carried out from a protected position and is resistant to heat, steam and dust. The system records to micron accuracy measuring values, gapless,

reliably measures independent of surface roughness in typical tube applications. Therefore, it contributes to a high product quality, process optimisation and potential cost saving in tube and pipe manufacturing. Another highlight on the Sikora stand was the Planowave 6000 M, a non-contact measuring system that is used for non-destructive thickness measurement of metal strips and plates. The system offers a precise thickness measurement independent of material, temperature and surface of the product. A calibration of the material is not needed. The measurement of

the product is accomplished by using millimetre waves- based radar technology. An optionally traversing set of transceivers above and below the strip or plate continuously sends and receives modulated millimetre waves. From the runtime difference, the thickness of the product is precisely determined. Sikora also showcased gauge heads of the Laser Series 2000 for non- contact and non-destructive measurement of the diameter and ovality of metal tubes, wire rods and bars during production. The measuring method is based on the usage of CCD sensors and laser light sources in combination with powerful signal processors. The outer diameter of the metal tube, wire rod or bar is calculated by means of an intelligent diffraction

analysis. Extremely low exposure times guarantee a high accuracy of the single value at all line speeds. The gauge heads are free of wearing parts, and keep their precision during the entire operating time. No calibration or maintenance work is necessary. In addition, Sikora presented the Laser Series 6000. These gauge heads expand Sikora’s current range of intelligent diameter gauges with three high-end models. Up to 5,000 measurements per second and axis, all with extremely high single value precision, enable optimum line control, provide reliable statistical data, and allow the detection of lumps and neckdowns at the same time. The Sikora gauge heads measure the diameter of tubes, wire rods and bars with precision and repeatability. Three gauge head models cover product diameters from 0.2 to 78mm.
