“…Different base metals and operating temperatures are typically in different job locations. The experimental data gained in this study from the temperature range serves as a significant reference for future applications when quick corrosion status diagnosis for unknown materials on-site is necessary, for example using FEM [46,47]. By comparing the collected velocity and decibel change data to the reference values, it is possible to quickly analyse the material's condition.…”

On-stream inspections are the most appropriate method for routine inspections during plant operation without going through production downtime. Ultrasonic inspection, one of the on-stream inspection methods, faces challenges when performed at high temperatures exceeding the recommended 52°C. This study aims to determine the ultrasonic velocity and attenuation with the known material grade, thickness, and temperatures by comparing theory calculation versus experiment with temperatures ranging between 30°C to 250°C on low carbon steel covering most petrochemical equipment material and working conditions. The theoretical analysis was to obtain Young's modulus, Poisson's ratio, and longitudinal velocity at different temperatures. The experiments validated the predicted results of ultrasonic change due to temperature increase and showed a maximum error of 3%. The experimental data of velocity and decibel change from the temperature range provide a reference for the future when dealing with unknown materials information on site that require a quick corrosion status determination.

“…It can acquire a more thorough understanding of the ultrasonic attenuation phenomenon by investigating thicker base metals and their behaviour under high-temperature settings. This knowledge would help to build more precise and dependable inspection strategies, allowing for effective corrosion mapping in various petrochemical plant equipment [50].…”

Petrochemical plants use on-stream inspection more often to detect and monitor the corrosion on the equipment and piping system. Compared to ultrasonic thickness gauging and pulse-echo A-scan, phased array corrosion mapping has better coverability and can scan a large area to detect general and localized corrosion. This paper's objective is to obtain documentary evidence on the accuracy of corrosion detection from 30°C to 250°C on A36 low-carbon steel by carrying out simulation experiments every 10°C steps. A minimum of three sets of phased array corrosion mapping data in each temperature were collected to study and evaluate the detectability. The data evidence could enhance the confidence level of the plant's end users to use the phased array mapping in the future during an inspection. The experiments were found to be insufficiently thorough despite addressing the initial concerns, leaving more area for discussion in further studies, such as expanding the investigation to thicker carbon steel, stainless steel, and wedge materials.

“…The advantage of this method is that when a rapid corrosion state diagnosis of an unknown material is required in the field, the machine can be set up quickly by examining the composition of the material and applying calculations to obtain a value for velocity. The data from this experiment can also be used for future applications, e.g., using finite element analysis [ 15 , 45 ].…”
