Seamless steel tubes are primarily used in oil fields and for oil drilling rigs in the oil and gas sector. To produce a seamless steel tube, the pre-tube (bloom) is drawn through a round continuous cast with a hole in one hot molding process.

DEFECTOMAT: The DEFECTOMAT product family is used for testing seamless steel tubes for point and transverse defects with the help of eddy current technology. When combined with the standard through-type coils, tubes with a diameter up to a maximum of 240 mm can be tested.

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 flux leakage method.

MAGNATEST D-HZP: The MAGNATEST D-HZP test system can be used for performing material identification checking and hardness checking on the test material. The system uses the magnetic-inductive method.

CIRCOGRAPH: The CIRCOGRAPH test instrument accurately scans seamless steel tubes for longitudinal defects. Rotating probes contactless scan the material surface using eddy current.

DEFECTOVISION: The DEFECTOVISION test systems uses heat-flow thermography. The analysis of the temperature spread detects and visualizes even the smallest surface defects such as in billets and seamless steel tubes.
