About Full-body inspection/Leakage testing

  • Internationally recognized test standards: Leakage testing according to SEP, DIN, ASTM, API, BS, JIS, ETTC, ENEL and others
  • Inspection: Full-body inspection using encircling coils or multiple segment coils. Often combined with weld seam testing
  • Materials tested: Any ferrous, nonferrous or austenitic materials
  • Tube size: Up to 12 in (30.5 cm)
  • Production speeds: 1???20m/min (3.3???656 fpm). Depends on production line and welding type
  • Magnetization: For ferrous tubes

Eddy current testing is an excellent means of ensuring that tubing is leak-proof. Tubes are tested by encircling coils or multiple segment coils that completely surround the tube body. The eddy current test equipment paint-marks critical defects and assigns each tube to a sort class according to its quality. Test results are fully documented for future verification of tube quality.PRÜFTECHNIK offers a wide variety of eddy current inspection equipment that ranges from the most basic test equipment to powerful testers with wide-reaching capabilites for integration into central production control systems and 8-channel inspection using multiple coil systems.
