Frequently Asked Questions
1. Can the quartz tubes be customized to specific dimensions? Yes, we specialize in custom manufacturing. We can produce tubes with outer diameters from 10mm to 500mm and lengths up to 6000mm based on your technical drawings.
2. What types of special shapes do you offer? Beyond straight tubes, we provide U-shaped tubes, spiral tubes, and complex customized structures including those with quartz flanges or closed ends.
3. Are vacuum-sealed designs available for high-pressure applications? Absolutely. We offer professional vacuum-sealed designs and flange connections to ensure optimal performance in demanding industrial environments.
4. What surface finishes can I choose from? We offer three primary surface treatments: high-precision polishing (both inner and outer), frosted finishes for light diffusion, and acid-etched surfaces for specific chemical requirements.
5. What is the typical wall thickness range for these tubes? Our standard wall thickness ranges from 1mm to 20mm, allowing for a wide variety of structural strengths depending on your project needs.
6. How are the tubes prepared for shipping? Each tube undergoes rigorous quality inspection and surface treatment (like acid washing) before being securely packed to prevent any damage during transit.
