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

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,

Black and bright bar

  • Offline inspection: For final quality check after straightening, peeling or polishing using conveyor system
  • Continuous drawing lines: Inline inspection of bars, Ø up to

Double-wall brazed tubing

  • Detects critical defects: Finds typical processing defects such as flaws in the inner and outer seam, copper spots and runs
  • Inline inspection: Immediate test results and feed

Hot rolled bar and rod

  • Quality control: Detection of defective areas in test material and assignment of test piece to a quality category 
  • Process control: Identification of defective rolling e
