摘要： In a method for the nondestructive testing of pipes made of ferromagnetic steel for flaws by means of stray flux, the pipe is magnetized by a constant field and the discontinuities in the near-surface region of the outer or inner surface of the pipe cause magnetic stray fluxes, which exit the pipe surface and are detected by probes of a test unit, wherein the association of the detected amplitude signals is performed on the basis of the amplitude height and/or the frequency spectrum with respect to an external or internal flaw via defined flaw thresholds respectively. For this, prior to associating the detected amplitude signals to an external or internal flaw, the angular position of the flaw relative to the respective magnetic field direction is determined, and a correction of the signals is carried out via a previously determined correction factor for amplitudes and/or frequencies of a perpendicular angular position.

摘要： The invention relates to a method for testing the driftability of metal tubes, wherein a cylindrical drift body having a defined diameter and a defined length is guided through the tube with defined force for ensuring a predetermined internal diameter and a minimum straightness. Virtual drifting is hereby performed instead of the physical drift operation.

摘要： A device for checking steel pipes during production and to a method using the device. The device includes a station for acquiring measurement data representative of physical measurements of the geometry of a pipe taken on an outside thereof, and a computer system configured to store template data applicable in a coordinate system and representative of overall geometry of a sizing body. In a chosen coordinate system, the system then provides a three-dimensional representation of parts of the pipe. For each part of the pipe, the system is referenced to determine a critical parameter, representative of the margin of passage of the sizing body inside a chosen part of the pipe. The method and device may thus establish a diagnostic of traversability of the pipe by a sizing body.
