成果简介	NOVELTY - The method for screening and detecting the first ingress of water into the insulation layer of a pipeline involves: sending low-frequency microwave signals from a dipole antenna or an array of dipole antennas; utilizing the pipeline under inspection as a coaxial waveguide to propagate the microwave signal; detecting changes in the microwave signal reflection caused by the presence of water patches in the insulation layer; and providing an early warning of the likely occurrence of corrosion under insulation by analyzing the signal reflection pattern. USE - Method for screening and detecting the first ingress of water into the insulation layer of a pipeline for oil and gas industries, power generation, and chemical processing. ADVANTAGE - The method utilizes low-frequency microwave signals transmitted through the pipeline structure, which acts as a coaxial waveguide, to detect moisture infiltration without the need for insulation removal. The system is designed to provide early warning signs of corrosion under insulation, allowing for timely remedial actions, such as resealing the cladding, thus preventing further corrosion and minimizing potential damage. The method enhances the accuracy and cost-effectiveness of pipeline inspection by employing a unique microwave antenna design, such as a dipole antenna or an array with a disturbed figure-eight radiation pattern. This design optimizes the propagation of microwave signals and improves detection sensitivity for water patches within the insulation, even in hard-to-reach or inaccessible pipeline sections, including those that are underground, underwater, or overhead. Additionally, the method aims to overcome the limitations of traditional non-destructive testing methods, such as ultrasonic testing and radiography, which struggle with penetrating insulation materials. By providing a non-invasive, microwave-based solution, this method seeks to offer a more efficient, safer, and lower-cost alternative to conventional methods while maintaining high accuracy and reliability in monitoring pipeline conditions. Furthermore, the integrity of insulated pipelines is crucial for safety, efficiency, and cost-effectiveness. The system's ability to provide real-time data on water ingress will support proactive maintenance strategies, ultimately leading to improved pipeline lifespan and reduced operational downtime. The system's ability to detect water ingress at early stages prevents the onset of severe corrosion and subsequent pipeline failure. This early warning system helps to mitigate operational risks, reduce maintenance costs, and extend the lifespan of the pipeline. By providing real-time data, the system supports efficient pipeline management and the prevention of costly damage caused by corrosion under insulation. The method offers a significant advancement in the field of non-destructive pipeline monitoring, providing an efficient, cost-effective, and reliable method and preventing costly damage to pipelines. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a system for detecting corrosion under insulation in a pipeline; and (2) a method of inspecting pipelines for corrosion under insulation.
