Product Description
1. One-Piece Forming – Reliable Sealing
- Flange and tube body formed in one piece or precision-welded — no weld seam leakage risk
- Precision-ground end faces with high flatness and smooth finish
- Excellent vacuum sealing performance with O-rings / gaskets
- Meets high-vacuum and positive-pressure gas-tightness requirements
2. Ultra-High Purity – Zero Contamination
- SiO₂ purity ≥ 99.99%, premium grades up to 99.995%
- No devitrification, volatilization or particle shedding at high temperatures
- Zero metal contamination in semiconductor process gas lines
- Safeguards wafer / device process yield
3. Extreme Heat Resistance for Demanding Processes
- Long-term service temperature 1100°C – 1200°C, short-term up to 1400°C+
- Flange area withstands the same temperatures as the tube body — no weak points
- Compatible with diffusion furnaces, CVD, epitaxy and other high-temperature processes
4. Thermal Shock Resistant – Strong Crack Resistance
- Ultra-low thermal expansion coefficient (5.5×10⁻⁷/°C)
- No cracking or deformation under repeated heating and cooling cycles
- Low thermal stress at the flange-to-tube joint — long service life
5. Strong Corrosion Resistance – Chemical Inertness
- Resists strong acids (except HF) and various corrosive process gases
- No reaction with chlorine, halides, oxygen etc. at high temperatures
- Resists erosion and deposition — stable long-term performance
6. Precise Dimensions – Excellent Installation Compatibility
- Strict control of flange OD, bolt-hole spacing and end-face flatness
- Precise tolerances on tube OD, wall thickness and length
- Quick alignment and installation with standard metal flanges and seals
- Custom manufacturing supported per equipment drawings
7. Complete Specifications – Deep Customization
- Flange types: flat flange, KF flange, CF flange, custom-shaped flange
- Tube diameter: φ10mm – φ300mm (larger available on request)
- Length: customizable as required, up to 3 meters or more
- Structures: single-ended flange, double-ended flange, flange + reducer, flange + end cap
- Processing: end-face grinding, polishing, chamfering, flame-polished openings
