“…, and dissolved O 2 , H 2 S, CO 2 in the sedimentary water on steel plates of oil storage tank can penetrate the neighborhood crumbling anticorrosion sealing and results in setting erosion in the coating [6][7][8], and causes puncturing and spillage. Thus, intermittent investigation is important to anticipate decimation of steel plates of oil storage tank erosion.…”

The steel plate Grade S355GT st52 of KAR Group is used for the construction of storage tanks for oil works in KAR storage tanks. In this study we have found out the chemical and physical changes of the welded steel plate after the damage happened due to the ISIS attack in Bai-Hassan in Kirkuk. After receiving the samples of burned and heated steel plates, it has been machined the samples for tensile, hardness, chemical analysis and microstructural analysis. The plate thickness is reduced in certain areas of the plate due to oxidation at high temperatures of the material occurred especially at the weld area and the thickness of the plate is found to be between 13 and 18 mm. Due to the coarsening of the microstructure and the development of Widmanstatten ferrite which is a weak and undesirable microstructure has been seen in the microstructure of this steel. Extraction of Acoustic Emission (AE) signal features (magnitude, power, hit, time period and rise period varies with time and the relation between them) will use for identifying the corrosion level and diagnosing the type of corrosion of the steel plates of oil storage tank, and moreover to measure the corrosion severity of the complete storage tank.

“…The tank bottom corrosion damage is a very complex process. Several ions such as Na + , Ca 2+ , SO 4 2− , Cl − , S 2− , and dissolved O 2 , H 2 S, CO 2 in the sedimentary water on tank bottom can induce the corrosion, especially the chloride ions can invade the local deterioration anticorrosion coating and result in pitting corrosion under the coating, even perforation and leaking . Hence, periodic inspections are necessary to prevent destruction from bottom corrosion.…”

“…The acoustic emission sources released from metal deformation and cracking itself are considered as direct acoustic emission sources, whereas the hydrogen bubbles activation, passive film rupture, pits propagation and corrosion products movement in the corrosion process belong to indirect acoustic emission sources . The hydrogen bubbles activities resulting from proton reduction and corrosion products movements have been suggested as the main acoustic emission sources in both crevice and pitting corrosion . Acoustic signals released from passive film rupture can also be detected in stainless steel, aluminum and aluminum alloy pitting corrosion .…”

The pitting corrosion characteristics of low carbon steel specimens are studied by acoustic emission (AE) and electrochemical techniques, in a 3.0 wt.% NaCl solution acidified to pH 2.0. The acoustic emission signals generated by pitting corrosion are classified based on multiple acoustic emission parameters using K-means clustering algorithm, then each classified signals are analyzed by acoustic emission parameters correlation plot and distribution with time. Furthermore, each acoustic source characteristics is extracted using Gabor wavelet transform (WT) in the time and frequency domain. An error back propagation (BP) artificial neural network (ANN) is trained according to the classified signals, so as to successfully identify the acoustic emission signals from parallel experiments. Experimental results show that the hydrogen bubble activation, oxidized film rupture and pit growth are typical acoustic emission sources in pitting corrosion process, which can be effectively classified by cluster analysis and recognized by back propagation neural network. The data gathered from laboratory tests combined with the real data from acoustic emission online storage tank floor inspection can help to evaluate the bottom corrosion severity and interpreter the corrosion source, further to make the on-site testing more reliable and reduce the risk.
