The Institute of Metal Physics has developed a computer-aided system that provides automated nondestructive magnetic testing of straight-line-seam electric-welded pipes of up to 530 mm in diameter during production workflow. A unique single-crystal thin-film matrix sensor, which is made using up-to date nanotechnologies, allows the working gap to be increased up to 5 mm. This feature contributes considerably to the reliable detection of longitudinal, transverse or oblique flaws as well as flaws caused by the breach of welding conditions.

The installation provides testing around the periphery of pipes and throughout their wall thickness. It surpasses the ROTOMAT analogs (Dr. Förster Institute) in the reliability of primary transducers and in detection of defects such as sticking and displacements of weld edges. The installation can be used in metallurgy, pipe making, construction, machine building, oil and gas facilities, and housing and communal services. At present, over 30 automatic installations of UMD-101 type, which have been designed at the Institute of metal Physics, are operated in industry
