How to detect leaks in a self-bundled tank

1. Routine Visual Inspection
Regularly conduct visual inspections of the area around the tanks, clearing debris from the tank area and observing for signs of media seepage between the inner and outer tanks and at the bottom of the tanks. Check the tank surface for rust, damage, or abnormal seals. Also, observe the ground and soil around the tank area for oil stains, discoloration, or other abnormalities. If corrosive media are stored, pay attention to whether surrounding vegetation shows abnormal wilting. Use sensory evaluation to initially identify potential leaks.
2. Built-in Monitoring System Detection
Utilize the tank's built-in monitoring system for real-time detection. Sensors are deployed in the interlayer between the inner and outer tanks and at key locations within the tank area to monitor changes in media concentration, humidity, or pressure in real time. When abnormal values ​​are detected, the system automatically triggers an audible and visual alarm and uploads the data to the control terminal, allowing personnel to quickly locate the leak and take rapid action, achieving early detection and early warning of leaks.
3. Specialized Sealing Performance Testing
Regularly conduct sealing performance tests, using methods such as pressure testing or vacuum testing to specifically inspect the seals of the tanks and accessories. By injecting inert gas into the tank or maintaining a specific pressure, observe whether the pressure value stabilizes. An abnormal pressure drop may indicate a leak. For leak-prone areas such as valves and interfaces, a foaming agent can be applied; the formation of bubbles indicates a leak.
4. Post-Detection Data Review and Maintenance
Establish a data recording mechanism to regularly review monitoring system data, visual inspection results, and specialized test reports to identify leak detection patterns. Simultaneously, regularly calibrate and maintain the detection equipment to ensure the normal operation of sensors and alarm devices, and promptly replace aging components. Optimize the detection frequency and methods based on the characteristics of the storage medium to improve the accuracy and reliability of leak detection.
