Yes, understanding the precautions for operating LNG and industrial gas (O₂/N₂/Ar) breakaway valves is critical for safety. Key注意事项 (Precautions) include:

1. Material Compatibility

   • For oxygen (O₂) service: Valves must be degreased and cleaned for oxygen use to prevent combustion risks.

   • For LNG/cryogenic service: Materials must tolerate -162°C temperatures without brittle fracture.

2. Regular Inspection

   • Check for corrosion, seal wear, and mechanical damage before each use.

   • Verify that the valve has not exceeded its service life or been triggered previously.

3. Triggering Conditions

   • Do not test by forcibly pulling the valve—accidental activation requires immediate replacement.

   • Ensure the pull cable (if equipped) is accessible but protected from unintended contact.

4. Post-Trigger Action

   • Once activated, the valve must be replaced entirely, even if it appears undamaged. Reuse is prohibited.

5. Environment-Specific Rules

   • LNG valves: Prioritize thermal insulation integrity to prevent ice buildup.

   • O₂ valves: Strictly enforce oil-free tools and gloves during handling.

6. Training & Documentation

   • Only trained personnel should operate or maintain these valves.

   • Maintain logs of installation dates, inspections, and triggering events.

Remember: Neglecting these precautions can lead to leaks, explosions, or equipment failure. Always adhere to standards like ISO 28460 (LNG) and CGA G-4.1 (Oxygen).

Final Note: When in doubt, consult the valve manufacturer’s guidelines—safety protocols vary by design and application.
