Technical Specifications

CF Blank Flange Fixed Frequently Asked Questions (FAQ)

1. What vacuum environments is the CF Blank Flange Fixed suitable for?

Designed for ultra-high vacuum (UHV) systems, supporting up to 10^-9 Torr and beyond.

2. How corrosion-resistant is the stainless steel CF flange?

Made of 316L stainless steel, offering excellent chemical corrosion resistance for harsh environments.

3. Why use copper gaskets for high vacuum sealing flanges?

Copper gaskets (pure/oxygen-free copper) provide high ductility and airtightness, ensuring vacuum integrity.

4. What should be considered when installing semiconductor vacuum components?

Ensure flange surfaces are clean and scratch-free, and use a torque wrench to tighten bolts properly without over-compressing gaskets.

5. Can ultra-high vacuum flanges be customized to non-standard sizes?

Yes, we support custom manufacturing for different sizes and materials.

6. How to determine if vacuum system closure components need replacement?

Check for vacuum leaks, gasket degradation, or flange deformation—replace immediately if found.

7. Which industries use fixed blank flanges?

Widely used in semiconductor equipment, scientific instruments, and aerospace testing systems.

8. What is the flatness requirement for scientific instrument sealing flanges?

Typically ≤0.001mm flatness error to ensure ultra-high vacuum sealing.

9. Are aerospace vacuum components heat-resistant?

316L stainless steel and copper gaskets withstand baking temperatures (200°C~300°C) for UHV degassing.

10. How to clean and maintain CF flanges?

Use lint-free cloth + alcohol for cleaning; avoid abrasives. Regularly inspect gasket condition.
