Optimised Detection and Sizing of Pipe Corrosion at Supports Using Guided Wave Technology


Venue: Training Room T1C, No. 9 Jurong Town Hall Road, TA Hub
Speaker: Dr. Chua
Date: 20 May 2024
Time: 06:00pm - 09:00pm
Registration Close Date: 16 May 2024



Corrosion under pipe supports (CUPS) represents one of the most prevalent pipe defects encountered across oil, gas, and petrochemical facilities, posing serious risks of pipeline structural failure and ultimately product containment loss. Despite being external in nature, locating CUPS remains a formidable task due to the sheer number of pipe supports per pipeline, often numbering in the hundreds. Conducting visual testing for each support proves impractical, particularly when pipes are elevated on racks or insulated. Addressing this challenge, this presentation introduces an optimised methodology for CUPS detection and sizing. This approach integrates a broadband-guided wave screening technique which complies with ASTM E2775-16, ensuring reliable detection of CUPS over extensive pipe lengths. Additionally, an accurate guided wave scanning technique is employed for precise quantification of the remaining pipe wall thickness at corrosion sites. The efficacy of this method is demonstrated through inspection results obtained from an 8-inch pipeline situated on a pipe rack within a petrochemical complex, identified as a critical asset by its owner. These results showcase the early detection of several CUPS defects and provide insights into the extent of damage in terms of remaining pipe wall thickness. Through the synergistic utilisation of guided wave screening and scanning techniques, this methodology offers a robust solution for enhancing CUPS detection and facilitating proactive maintenance strategies within industrial facilities.
