Tank Commissioning Procedures
Systematic steps for ensuring proper installation, functionality, and safety of storage tanks before operational use
1
Appearance and Connection Inspection
- Conduct a comprehensive visual inspection of the tank's exterior, checking for deformation, damage, or paint peeling.
- Verify the sealing performance at all connection points, examining flanges and interfaces for potential leaks.
- Ensure all seals are properly installed and tightly fitted to prevent medium escape during operation.
- Inspect accessory installation, confirming that level gauges, pressure gauges, and valves are securely connected without looseness.
- Validate the proper assembly and positioning of all components before proceeding to functional testing.
2
Sealing Test
- Perform a water or gas filling sealing test, selecting the appropriate method based on the tank's medium characteristics.
- Slowly inject the test medium while gradually increasing pressure to the specified standard levels.
- Maintain stable pressure for the required duration while monitoring for leaks, pressure drops, or abnormalities.
- Continuously observe the entire test process, including tank body and all connection points.
If leaks are detected, immediately stop the test, conduct repairs, and retest until all sealing requirements are met.
3
Ancillary System Commissioning
- Start the tank's auxiliary control systems and monitoring equipment for initial functionality checks.
- Calibrate level monitoring devices to ensure accurate and timely data feedback during operation.
- Test valve functionality, verifying smooth opening/closing operations and effectiveness of sealing mechanisms.
- Verify the proper operation of drainage, feeding, and discharging systems for smooth material transfer.
- Debug anti-corrosion and insulation facilities to confirm they meet operational requirements and coordinate with the main tank.
4
No-load and Load Trial Runs
- Begin with a no-load trial run to check component operating status and overall equipment stability.
- Identify and eliminate abnormal noises, jamming, or mechanical issues during the no-load test.
- After successful no-load testing, proceed to load trial runs with actual operating medium.
- Monitor tank performance under load conditions, including pressure changes and system coordination.
- Conduct a comprehensive post-trial inspection; if no abnormalities are found, the tank is ready for normal operation.
Final Verification Protocol
All commissioning procedures must be thoroughly documented, with test results recorded and reviewed by qualified personnel. Only after successful completion of all four steps—visual inspection, sealing test, ancillary system commissioning, and trial runs—should the tank be approved for regular operational use. Regular re-verification should be scheduled according to manufacturer recommendations and regulatory requirements.
