Product Usage Guidelines of UV Quartz Tube
Handling & Installation
- Handle with care to avoid impacts or drops that could cause microscopic cracks or breakage.
- For high-temperature applications, clean thoroughly and wear lint-free gloves during installation to prevent contamination.
- Use appropriate O-rings and mounting hardware designed for UV applications to prevent leaks and ensure proper alignment.
Operation & Maintenance
- Never exceed the maximum operating temperature (1100°C continuous, 1450°C short-term) to prevent softening and deformation.
- Avoid contact with alkaline substances (sodium/potassium compounds, water glass, asbestos) at high temperatures, as these will significantly degrade performance.
- Regularly clean with appropriate non-abrasive solutions to maintain optimal UV transmittance and prevent scaling in water applications.
