High Light One-Piece Formed Quartz Flange TubeUltra High Purity Zero Contamination Quartz Flange TubeHigh Temperature Resistant Quartz Flange Tube for Semiconductor Gas Lines

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
