Petrochemical plants use on-stream inspection 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 for the accuracy of corrosion detection from 30 °C to 250 °C on A36 low-carbon steel by carrying out simulation experiments every 10 °C step. 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 in using phased array mapping in the future during inspections. 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.
石化工厂经常进行在线检测，以检测和监测设备及管道系统的腐蚀情况。与超声波测厚仪和脉冲回波A扫描相比，相控阵腐蚀测绘具有更好的覆盖性，能够扫描大面积区域以检测全面腐蚀和局部腐蚀。本文的目的是通过每隔10°C进行模拟实验，获取关于A36低碳钢在30°C至250°C范围内腐蚀检测准确性的文件证据。在每个温度下至少收集三组相控阵腐蚀测绘数据，以研究和评估可检测性。这些数据证据能够提高工厂终端用户未来在检查中使用相控阵测绘的信心水平。尽管解决了最初的担忧，但实验仍不够彻底，在进一步研究中仍有更多可讨论的领域，例如将研究范围扩大到更厚的碳钢、不锈钢和楔块材料。
