Insulation Moisture and corrosion detection
While most corrosion detection solutions focus on identifying corrosion after it has already occurred, the Wenzhou Leak & Corrosion (LCH) system takes a proactive approach by targeting the root cause: moisture. Trapped moisture beneath insulation creates a breeding ground for corrosion, making early intervention crucial to preventing long-term damage. This article explores how the LCH system effectively monitors moisture, halts the spread of corrosion, and helps industries maintain asset integrity.
Understanding the Link Between Moisture and Corrosion
Moisture is a critical factor in Corrosion Under Insulation (CUI). When water or humidity becomes trapped beneath the insulation layer, it creates an ideal environment for corrosion to develop. The challenge with CUI is that damage often remains hidden beneath the surface; by the time visible signs appear, the corrosion may have already reached a dangerous level.
This is where the LCH system proves invaluable. Utilizing technologies such as resistance, impedance, and electrochemical monitoring, the system detects moisture early, identifies potential corrosion risks, and enables operators to take action before significant damage occurs. Early detection of moisture—combined with LCH corrosion rate sensors—effectively minimizes long-term issues.
Monitoring Principles
The LCH system monitors moisture levels within the insulation of pipelines or storage tanks. It employs specialized drainage and isolation brackets to embed copper sensing wires within the insulation, maintaining their straight alignment. Using various detection principles—including resistance, impedance, and electrochemical analysis—the system detects any changes in moisture or humidity within the insulated area.
The system analyzes temporal and spatial humidity patterns and integrates data from LCH corrosion rate sensors to pinpoint "hotspots" most susceptible to corrosion. This real-time data allows operators to precisely monitor equipment health and implement preventive measures before corrosion escalates.
From Moisture Detection to Corrosion Identification
Upon detecting moisture, the system immediately alerts operators and pinpoints the problem area via a visual dashboard and detailed reports. The LCH system is designed not only to detect moisture and leaks but also—in conjunction with LCH corrosion rate sensors—to assess the likelihood of corrosion progression. Key features of the system include:
• Continuous Monitoring: The system tracks moisture levels around the clock, providing real-time information that enables proactive maintenance.
• Precise Localization: It detects moisture at specific locations along the pipeline, providing targeted information to address potential CUI (Corrosion Under Insulation) issues.
• Cost-Effective Solution: By identifying corrosion risks early, the system helps reduce expensive repairs and downtime, thereby extending the service life of your infrastructure.
• Non-Invasive Monitoring: There is no need to remove insulation or cladding, which significantly lowers inspection costs and minimizes the risk of asset damage.
Why LCH is the Better Choice
Unlike traditional inspection methods—which can be slow, costly, or limited in scope—LCH offers a comprehensive solution compliant with EN 14419. It not only detects moisture and leaks but also utilizes corrosion sensors to understand how moisture leads to corrosion, allowing issues to be resolved before they escalate. Combining real-time data, reliability, and the ability to monitor without interrupting operations, LCH is the ideal solution for managing CUI.
With LCH, all risk points can be identified. Furthermore, the false alarm rate is significantly reduced, leading to substantial savings in inspection costs. Because the system clearly indicates which areas require attention and which do not, manual inspections become more precise and efficient, further lowering costs. Spatiotemporal changes in CUI indicator values can also be used to trace the source of moisture ingress and effectively repair damaged cladding.
The result is a reduction in accidents and downtime, alongside lower operational costs for CUI inspection and maintenance.
