About Multivoid tubing

Air conditioner tubing is inspected inline after extrusion. An encircling coil tests for outer surface defects and checks that the walls of the interior chambers are intact. It is specially designed for this tube shape.The eddy current signals are transmitted to an eddy current inspection unit that analyzes the signals for defects. The unit also controls marking of the defects and sorting of the test piece. Test results can be printed out immediately or stored for future reference.

Radiator tubing


Radiator tubing is inspected inline after welding using an eddy current probe.The eddy current signals are transmitted to an eddy current inspection unit that analyzes the signals for defects. The unit also controls marking of the defects and sorting of the test piece. Test results can be printed out immediately or stored for future reference.

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,

Seamless tubing

  • Inspection: Encircling coil for full-body inspection. For a more thorough inspection, a rotating system is used simultaneously for identifying longitudinal grooves.
  • Production typ

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
