About Rotational testing

  • Products tested: All seamless products that are round or off-round
  • Production types: Straightening lines, continuous drawing lines, offline final inspection
  • Inspection: Integrated into production line or used in final offline inspection
  • Materials tested: Ferrous, austenitic, nonferrous metals
  • Test piece diameter: 2???130 mm (0.08???5.12 in)
PRÜFTECHNIK's rotating systems are designed specifically to identify longitudinal, homogenous cracks and fissures found at the surface of the test piece. They are used for products that have a tendency to show longitudinal defects but do not have seam welds. Because the encircling coil is ideal for finding short transverse defects, it is often used in conjunction with the rotating system for a comprehensive testing strategy. PR??FTECHNIK offers a series of rotating systems (RS35HS, RS65, RS130) to cover a wide range of tube diameters. They are particularly easy to operate and maintain and are extremely robust to withstand the industrial environment. Precise test piece guidance and a lift-off compensation system ensure accurate test results.
Eddy current inspection equipment suited for use with the rotating system includes the EDDYCHEK S and the EDDYCHEK 5, depending on the testing capabilities required. 

Reated Projects

Thick material inspection (TMI)

Application fields

  • Production type: thick-walled tubes with a longitudinal weld seam; welded seams can be tested in their full thickness
  • Materials: austenitic steel, aluminum, br

Continuous drawing line

  • Input control: Identification of bad quality rolled wire (drawing lines for thick wire)
  • Process control: Monitoring of production lines to avoid scrap (medium and fine drawing bloc
