Applications of the Acoustic Emission Method

An integral check of all sizes of pressure vessels, piping, pressure reservoirs, reactors, autoclaves, storage tanks, boilers, heat exchangers, etc. Both in off line pressure tests and in uninterrupted operation.

A local check of selected critical points of a structure, and at the same time additional points across a structure, e.g. selected welded joints, critically stressed areas, places inaccessible to other checks etc. both in pressure tests and in uninterrupted operation.

An immediate detection and location of fluid leakage due to a through crack ensuring a timely removal of the structure from operation before its final fracture.

Detection of external leakage, internal leakage, leakage of valves, fittings etc, in boiler rooms, electric power stations, piping systems, heat exchangers, etc., improving the effectiveness and reliability of plant operation.

Advantages of the Acoustic Emission Method

The AE method enables a check to be made in a real time.

The AE method enables an integral check of large areas to be made, including places, which are inaccessible to other methods.

The AE method enables the location of the origin of the Acoustic emission activity.

The AE method detects processes, which are active acoustically (the formation and growth of defects, leakage of medium, etc.). The development of acoustically active processes is initiated by a complex of causes and conditions.

The AE method enables a simultaneous check of various failure processes in terms of one diagnostic system only. For example, the simultaneous check of the growth of a defect, leakage, loose parts, etc all detected at same time.
