How to Detect Leaks in a Self-Bundled Tank

Routine Visual Inspection

Regularly conduct visual inspections of the area around the tank, clearing debris from the tank area.
Observe for signs of media seepage between the inner and outer tanks and at the bottom of the tank.
Check the tank surface for rust, damage, or abnormal seals.
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.

				 Key Focus: Systematic observation and early visual identification of potential issues.
			

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.
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.
Data is uploaded to the control terminal, allowing staff to quickly locate the leak and take immediate action.
Achieves early detection and early warning of leaks.

				 Key Focus: Automated, real-time monitoring for immediate leak detection and response.
			

Regularly conduct sealing performance tests using methods such as pressure testing or vacuum testing.
Specifically inspect the seals of the tank and its 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, apply a foaming agent.
The formation of bubbles indicates a leak.

				 Key Focus: Proactive testing of system integrity to identify potential failure points.
			

Establish a data recording mechanism to regularly review monitoring system data.
Review visual inspection results and specialized test reports to identify leak detection patterns.
Regularly calibrate and maintain the detection equipment.
Ensure the normal operation of sensors and alarm devices.
Promptly replace aging components.
Optimize the detection frequency and methods based on the characteristics of the storage medium.
Improve the accuracy and reliability of leak detection.

Key Focus: Continuous improvement through data analysis and system maintenance.
