“…For this reason, testing for a high level of safety and the reliability of periodical maintenance of the tank and its floor should be performed, in order to avoid corrosion related accidents when hazardous chemical materials might get into the environment and groundwater. In order to avoid this, various NDT methods for the inspection of the construction elements in the petrochemical industry, such as penetrant testing, magnetics [1], eddy current [2], thermography [3,4], radiographic testing [5], acoustic emission [6], and ultrasonic techniques are used [7,8]. The main problems related to the inspection of the storage tanks and their floors using conventional NDT methods is that, in most cases, the tank has to be emptied, cleaned, and made safe for human entry before any inspection could be performed.…”

Abstract:The objective of the research presented here is the investigation of ultrasonic guided wave (UGW) propagation through the lap joint welded plates used in the construction of a storage tank floors. The investigations have been performed using numerical simulation by finite element method (FEM) and tested by measurement of the transmission losses of the guided waves transmitted through the welded lap joints. Propagation of the symmetric S 0 mode in the welded stainless steel plates in the cases of different lap joint overlap width, operation frequency, and additional plate bonding caused by corrosion were investigated. It was shown that the transmission losses of the S 0 mode can vary in the range of 2 dB to 8 dB depending on the ratio between lap joint width and wavelength. It was also demonstrated that additional bonding in the overlap zone caused by corrosion can essentially reduce transmission losses.

“…Here, the heat flux delivered onto a sample surface by an external source propagates in-depth and experiences specific disturbances on the defect regions. [11] The recent developments in IR camera measurements show its potential to consider it as a reliable technology for temperature measurements.…”

Infrared (IR) thermography was used to measure thermal profiles in the coating, consumable rod, and substrate during friction surfacing. A sudden raise followed by a steady state in thermal profile was observed and attributed to viscous heat dissipation during plastic deformation. The retreating side of the coating experienced higher temperature compared to the advancing side, indicating that the hot plasticized metal is carried from the advancing side to the retreating side.

“…When applying the ITWNDT to detect the corrosion, researchers often do not consider the corrosion products or dressed liquid in the tank [12], [17]. In order to accurately obtain the corrosion detection results, in particular to study the detection of in-service tank, material properties of corrosion products were set in the paper's calculation.…”

“…Some advantages of ITWNDT as intuitive test results, single-sided testing, non-contact, large area detection and quantitative detection were successfully applied in the aerospace, power generation, automotive, construction and other fields [5]- [10]. S. Marinetti [11]- [12], E. Grizato [13]- [14], D. Ambrosini [15], M. Jonsson [16] and Yang Jing [17] studied the application of ITWNDT in corrosion detection, and achieved relatively good results. Notwithstanding this, the influence factors in the thermal Wave NDT are still not completely exploited.…”

Due to the disadvantages of traditional NDT methods for liquid propellant tank corrosion detection, Thermal Wave Nondestructive Testing (ITWNDT) technology was applied. The heat exchange process of thermal wave in corrosion tank was simulated by the numerical method. Parameters of TWNDT as the best detection time (t best ), the maximum surface temperature difference (ΔT max ), and the temperature difference holding time (τ ΔT>0.1 ) were discussed as the targets. Based on these parameters, factors influencing the detection results of tank materials, dressed liquid (also considered as the corrosion product), pit characters (depth and size), heat flux and thermal excitation time length (pulsed width), environmental conditions and other factors were analyzed. Simulation results show that ITWNDT can identify the defect depth, size and position rapidly and effectively. Material properties of the tank were influencing the t best , ΔT max and τ ΔT>0.1 , while the dressed liquid, thermal excitation parameters and the conditions of environment do not influence the t best . Pit characters of the depth and size have close relationship with t best and ΔT max , therefore, for a tank with certain material and certain liquid dressed in, the pit corrosion damage can be accurately evaluated.
