About 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 types: Continuous drawing lines and level winders, hot rolling lines
  • Materials tested: Ferrous, austenitic, nonferrous aluminum, copper, brass, titanium, german silver, etc.
For the most comprehensive inspection of seamless tubing, a rotating system is used in conjunction with an encircling coil. The rotating system is extremely sensitive to longitudinal, homogenous cracks and fissures while the encircling coil is ideal for finding short transverse defects.PRÜFTECHNIK offers a series of rotating systems (RS35HS, RS65, RS130) to cover a wide range of tube diameters.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.
