Routine Perfection of Pipelines Diagnostics by Means of Acoustic Emission Technology

V. G. Kharebov, A. N. Kuzmin, A. V. Zhukov

The article describes some peculiarities of acoustic emission method practical usage for pipeline system diagnostics. The conclusion is made that the main technique weakness within the current regulations is necessity of forced pressure changing in order to achieve standard loading pattern. The proof is given that there is a possibility in principle to carry out testing of cross-country pipelines by acoustic emission method at current operating parameters, i. e. without forced pressure changing; this allows to get a considerable increase in quality and to optimize a procedure of underground pipeline technical diagnostics for a customer. The examples are given of such schema usage for testing of cross-country pipeline underground areas without any loss in testing efficiency.
