Acoustic Emission (AE) Testing for Online Monitoring of Storage Tank FloorsNew!!
Large storage tanks at petroleum and chemical plants and liquid cargo terminals suffer primarily from floor-plate corrosion, which has historically required tank-opening (internal) inspection to confirm integrity. Thanks to the maturation of Acoustic Emission (AE) testing, however, corrosion activity can now be monitored in real time without taking the tank out of service. This article […]
How PAUT Is Transforming Plant Inspection: TFM/FMC and On-Stream Corrosion Mapping [2026 Update]New!!
Phased Array Ultrasonic Testing (PAUT) has evolved from "another UT method" into the cornerstone of modern plant inspection. The latest generation adds TFM (Total Focusing Method) and FMC (Full Matrix Capture), allowing high-resolution imaging that captures wall-thickness variations across complex geometries in a single scan. Coupled with the trend toward on-stream (in-service) corrosion mapping, PAUT […]
Distributed Fiber Optic Sensing (DFOS) for Continuous Pipeline Monitoring — The Next Step Beyond AE in Online NDT [2026 Update]New!!
Following our previous article on Acoustic Emission (AE) monitoring of tank floor plates, this post focuses on another rapidly expanding online monitoring technology for process piping: Distributed Fiber Optic Sensing (DFOS). While AE excels at localized acoustic detection, DFOS turns a single optical fiber cable, spanning tens of kilometers, into a continuous chain of virtual […]
