Tank Cleaning & Maintenance Guide
Professional procedures for safe and effective tank cleaning operations
Preparations Before Cleaning
- Completely empty the tank of its contents, close all valves, and ensure proper isolation to prevent backflow during cleaning.
- Thoroughly ventilate the tank to reduce the concentration of volatile gases and avoid safety risks.
- Operators must wear appropriate protective equipment and ensure personal safety.
- Before entering the tank, test the gas composition and oxygen content to ensure compliance with safety standards.
Safety Note
Always verify the tank environment is safe before entry and maintain continuous monitoring during operations.
Scientific Cleaning Methods
- Select an appropriate cleaning method based on the type of deposits inside the tank.
- Prioritize neutral detergents and avoid the use of highly corrosive chemicals that could damage the inner wall coating.
- For stubborn deposits, use manual wiping or specialized cleaning tools to gently clean them.
- Avoid using tools that may generate sparks during cleaning to prevent potential safety hazards.
- Pay special attention to cleaning dead corners and weld seams on the inner wall of the tank.
Thorough Residue Removal
- After cleaning, rinse the inner wall of the tank multiple times with a suitable cleaning medium or clean water.
- Continue rinsing until the flowing liquid is clear and free of impurities.
- After rinsing, ventilate and dry the tank again, using natural or auxiliary ventilation.
- Ensure no moisture remains on the inner wall to prevent subsequent corrosion.
- Check the tank for any remaining tools or debris and clean them promptly.
Post-Cleanup Protective Measures
- After cleaning and drying, carefully inspect the inner wall of the tank for any coating damage, rust, or other issues.
- Repair any problems found immediately.
- Seal all interfaces and openings of the tank to prevent dust, debris, or moisture from entering.
- Keep a cleaning record, specifying the cleaning time, method, and inspection results.
- If the tank is to be stored for an extended period, periodically check the sealing condition and internal environment.
