Seamless or welded profile section tubes with square, rectangular, or profiled cross-section are used for numerous applications. They are used for scaffolding as well as vehicle and window manufacture.
FOERSTER units are used for testing tubes with various profiles for surface defects using non-destructive technology:

DEFECTOMAT: FOERSTER has developed the DEFECTOMAT product family for the testing of point and transverse defects. Eddy current technology is used for reliably testing even profiled tubes.

DEFECTOMAT sensor through-type coil: Various DEFECTOMAT sensor through-type coils adjusted to fit various shapes are available for the testing of profiled tubes. We also develop individual solution specifically tailored to meet our customers' requirements for specific test tasks. Probes can also be used for testing critical points.

MAGNATEST D-HZP: The MAGNATEST D-HZP test system is ideal for material identification checking and heat treatment checking in semi-finished products. The system uses the magnetic-inductive method.

ROTOMAT/TRANSOMAT: The ROTOMAT and TRANSOMAT test systems were specially developed for tubes with large diameters. They test the inner and outer tube for surface defects using the dc-field flux leakage method.
