About 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 defect-free compound tube, the intermediate metal layer of aluminum or stainless steel is inspected for holes or cracks. Usually, the weld seam of the internal tube presents a weak spot and is tested using a segment coilbefore the outer plastic layer is extruded over the metal. The eddy current signals are transmitted to the eddy current inspection equipment that evaluates it, identifies defects, marks the damaged areas and documents the results for future reference.

Butt weld detection

Butt weld detection

Butt welds cannot be identified by simple detectors such as the light barrier or proximity switch. The EDDYSENSOR locates the butt weld using eddy current t

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 bloc
