Frequency magnetic ferromagnetic FLAW UNDERGROUND PIPELINE

摘要

The invention relates to the field of nondestructive testing of ferromagnetic pipeline and can be used for rapid diagnosis outer pipe arranged underground.; The object of the utility model is an extension of the scope magnitoimpulsnyh flaw and increase ease of use.; Magnitoimpulsny flaw subterranean ferromagnetic pipes (pipes) comprises electrical pulse generator, generator coils, measuring coils EMF of the eddy currents induced in the pipes after switching off the magnetizing current in the transmitter coil inductance and placed on the moving platform of the magneto-transparent-material moved over the surface land along the ground track of the underground pipeline, while it is provided with a metal detector and a positioning device ground through Globe nuyu Navigation Satellite System - GLONASS, or Global Positioning System - GPS. The dimensions of the radiating antenna with generator coils, are chosen from the condition of coverage influence their magnetizing current of underground pipes, laid on the track, and the dimensions of the receiving antenna with the measuring coil, chosen for each tube individually with the diameter of the pipe, the detector size is also consistent coverage condition his action of all pipes, laid on the track.
