Quality Assurance of Seamless and Welded Steel Tubes on a Completely New Level
With the new generation ROTOMAT DA and TRANSOMAT DA flux leakage test systems FOERSTER is setting new standards in continuous quality assurance of ferromagnetic steel tubes. The test systems enable the reliable detection of natural and oblique defects, regardless of their angle or length, in addition to standardized longitudinal and transversal defects. The miniaturization of sensors together with highly integrated electronic components dramatically increases the number of channels. This makes a more precise and finer scan of the surface possible, giving a more complete set of information regarding detected defects. The newly introduced C-Scan visualizes these defects in high-definition and real-time, resulting in a completely new evaluation of the tubes to meet rising quality requirements.
The Highlights
- Reliable detection of natural and oblique defects regardless of length and angle
- Improved detectability of inner defects
- More precise decision between outer and inner defects
- Reduction of untested ends
