Acoustic Emission Leak Detection on a Technological Pipeline

Leak detection is one of the main tasks pipeline inspection, as extension pipelines usually requires a repair capability. Reliable and fast fluid leaks in extremely important for seaports, where their branched system located. The most frequent locations leakages are seam weldings flanged joints, which exposed to plastic deformation. aim this study was detect technological connecting two vertical bitumen storage tanks. Based on spectral analysis acoustic emission signals (AE), characteristic picture micro-damage process course (leakage, delamination, cracking, rupture, etc.) obtained.
