Application of the Method of Magnetoelastic Acoustic Emission for the Analysis of the Technical State of 19G Steel After Long-Term Operation in an Oil Pipeline

We study the microstructure of 19G steel of oil pipes after the operation of these pipes for 48 years. The degree of damage to the material by pores in the cross section of the pipe wall is estimated. The regularity of changes in the parameters of signals of magnetoelastic acoustic emission along th...

Zusammenfassung:We study the microstructure of 19G steel of oil pipes after the operation of these pipes for 48 years. The degree of damage to the material by pores in the cross section of the pipe wall is estimated. The regularity of changes in the parameters of signals of magnetoelastic acoustic emission along the thickness of the pipe wall is established
