About 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 feedback on the production process
  • Offline inspection: Tubes can also be tested after production has been completed
  • Completely automated: Operators are free to carry out other tasks while PR??FTECHNIK equipment automatically tests, sorts and documents results
All of the world's major manufacturers of double-wall brazed tubing have chosen PR??FTECHNIK equipment for the quality inspection of their products. Experienced production managers rely on our eddy current testing equipment to detect the full range of critical defects and thus to provide important feedback on the production process. The EDDYCHEK 5 equipment distinguishes between inner and outer seam flaws, copper spots and runs, as well as other defect types.

Reated Projects

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 f
