其中剩余厚度是通过 ILI在线检测工具的现场测量捕获的例如超声波检测或自动清管器管道内部测量仪。超声波工具具有大约 ± 03 至 ± 06 mm的深度检测能力这提供了足够的分辨率来创建腐蚀区域的精确几何表示。包含腐蚀区域映射点的腐蚀深度单位壁厚及其在管道中各自的周向和纵向位置单位°的矩阵。

The remaining thickness is captured through on-site measurements using ILI (in-line inspection) tools, such as ultrasonic testing or automated pigging devices (internal measurement devices in the pipeline). Ultrasonic tools have depth detection capabilities of approximately ±0.3 to ±0.6 mm, providing sufficient resolution to create an accurate geometric representation of the corrosion areas, including a matrix of corrosion depth (unit: % wall thickness) and their respective circumferential and longitudinal positions (unit: °) in the pipeline.
