About Offline testing

  • Offline inspection: Final inspection of cut-to-length tubes, e.g. after drawing to precise diameter (precision tubes)
  • Conveyors: PR??FTECHNIK also provides conveyor systems for transporting tubes
  • Materials tested: Any ferrous, nonferrous or austenitic materials
  • Magnetization: Required for ferrous metals
  • End-to-end testing: Eddy current sensors are used for distinguishing individual pieces in end-to-end testing
Tubes are tested offline for a final quality check before delivery. Also, tubes that were sorted to scrap in the course of inline testing during production may be retested offline for more precise classification or for cutting out of defect-free sections. PRÜFTECHNIK supplies complete, customized conveyor systems and testing tables for offline inspection.PR??FTECHNIK offers a wide variety of eddy current inspection equipment that ranges from the most basic testers to powerful inspection systems with wide-reaching capabilites for integration into central production control systems and 8-channel inspection using multiple coil systems.

End-to-end testing

The eddy current sensor EDDYSENSOR is used instead of a light barrier to distinguish between individual test pieces in end-to-end testing.

Reated Projects

Compound tubing

  • Inspection: Identification of weld seam defects in the internal metal layer of compound tubing
  • Diameter: 10-60 mm (0.4-2.4 in)
To guarantee a

Cold heading machines

In the manufacture of small parts using cross-cutting or cold heading machines, high scrap rates often result from defective starting material. Testing the initial material and cutting out the defecti

Fine wire

  • Inspection: Continuous inspection using encircling coil
  • Wire characteristics: Diameters down to 0.05 mm; tungsten, molybdenum, etc.
  • Production line: Drawing and rewinding lines

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 blocks)<
