Complex research of fundamental dependences of non-thermal passive methods of diagnostics when developing the techniques to be applied for assessment of technical state of the oil and gas equipment
The paper presents the results of laboratory researches of fundamental dependences of the method of an acoustic emission and the method of the registration of magnetic flow dispersion fields which are carried out to confirm the hypothesis of these methods mechanisms interrelation, bound with the assessment of ferromagnetic materials structural changes under the influence of outer load forces. The plan of further researches when testing the steel samples with artificial defects on stretching and fracture is also presented. The specified researches are required for assessment of passive methods application effectiveness of nondestructive monitoring to evaluate the technical state of the real steel constructions which are operated in the oil, gas and drilling industries.
