The independent study evaluates two key electromagnetic (EM) pipeline inspection technologies, Remote-Field Technology (RFT) and Near-Field Technology (NFT), for assessing the condition of AWWA C303 bar-wrapped pipe (BWP).
Conducted by Simpson Gumpertz & Heger Inc., and discussed with APS Palo Verde Generating Station (PVGS), this study compares results from two vendors, including PICA Corp., by utilizing blind verification tests on 30 and 36-inch diameter pipes with varying defects.
The results of the “Independent Comparison of Electromagnetic Inspection Tools for AWWA C303 Bar-Wrapped Pipe” study were presented at the UESI Pipelines 2024 Conference, held from July 27-31 in Calgary. The findings generated significant interest among attendees, highlighting advancements in pipeline inspection technologies and the critical role of accurate condition assessment in managing infrastructure.
This comparison offers valuable insights into how each technology performs in detecting defects such as section loss in the steel cylinder and broken reinforcing bars. PICA’s Advanced NDT tools demonstrated the capability to detect various defects, proving that its RFT technology is suitable for high-resolution pipeline inspections. The study concludes that while both technologies have advantages, they each have limitations in terms of accuracy and the types of defects detectable, especially in different pipe conditions.
PICA’s experience in non-destructive testing (NDT) plays a significant role in ensuring precise results. Their tools provide essential insights for asset management, especially for critical infrastructure that cannot afford failure. The study offers an independent validation of PICA’s technology, showcasing its effectiveness in detecting critical pipeline issues.
By reading the full article in the ASCE Library, you can gain a deeper understanding of how these advanced technologies work in real-world conditions, enabling better decision-making for long-term pipeline asset management.
This independent study confirms PICA’s technologies offer high-resolution, non-invasive inspection capabilities that provide accurate data, helping utility operators and asset managers detect and resolve issues such as corrosion, cracks, or reinforcing bar failures.
Using advanced RFT tools, PICA allows for precise detection of defects in all pipes with metallic components, aiding in better asset management strategies and reducing the risk of unexpected pipeline failures. Our tools and methods can significantly extend the life of critical infrastructure, save costs, and enhance operational reliability.
