OD 3-300mm quartz flange
Q: Are you looking for a high-temperature resistant, high-purity, and precisely sized connecting component?
Answer: OD 3-300mm quartz flanges are designed specifically for industrial applications that require stable performance in extreme environments, addressing your sealing, corrosion resistance, and high temperature resistance needs.
Q: How can it help you improve system reliability?
Answer: With high chemical purity and low thermal expansion coefficient, quartz flanges can effectively prevent pollution, reduce thermal stress cracking, and are suitable for fields such as semiconductors, photovoltaics, optics, and chemical engineering.
Quartz flanges, as key connecting and sealing components in industrial systems, are widely used in high-purity, highly corrosive, and high-temperature environments. Our company focuses on customized quartz flange production, with product diameters ranging from 3mm to 300mm, which can meet the demanding needs of global customers in the fields of semiconductors, photovoltaics, chemicals, optics, and scientific research.
Product advantages
1. High purity and chemical stability
Using high-purity quartz sand (SiO ₂) with a purity of over 99.99% as raw material, the product is resistant to acid and alkali corrosion (except for hydrofluoric acid and hot phosphoric acid), suitable for strongly corrosive media environments, and has no leaching pollution.
2. Excellent thermal performance
The coefficient of thermal expansion is extremely low (about 5.5 × 10 ⁻⁷/℃), and it can withstand drastic temperature changes from -200 ℃ to 1150 ℃ without deformation or cracking. Its thermal stability far exceeds that of metals and ordinary glass.
3. Excellent optical and electrical properties
The transmittance is over 93% (UV to IR band), with strong insulation and low dielectric loss, suitable for optoelectronic combination systems and high-frequency applications.
4. Precision machining and customization capabilities
Support CNC precision carving, laser cutting, high-temperature polishing and other processes, with dimensional tolerances controlled within ± 0.05mm and surface roughness Ra ≤ 0.4 μ m, ensuring sealing performance and system compatibility.
Main application areas
-Semiconductor and photovoltaic industry: diffusion furnaces, CVD/PVD equipment, etching chambers, flange connections and window components in photovoltaic cell manufacturing.
-Chemical and Pharmaceutical: High purity chemical medium transportation pipelines, reactor observation windows, corrosive gas treatment systems.
-Optoelectronics and lasers: sealed connections for optical equipment, laser cavities, and transparent components for UV curing systems.
-Research and Laboratory: Vacuum System, High Temperature Experimental Equipment, Spectral Analysis Instruments, Special Lighting Equipment.
-Environmental Protection and New Energy: Smoke Monitoring Devices, Fuel Cell Components, Semiconductor Exhaust Gas Treatment Systems.
Specifications and Customization Services
Diameter range: 3mm -300mm (supports non-standard sizes)
Thickness range: 1mm -50mm
Connection form: flat flange, convex flange, groove flange, threaded interface, quick fit clamp type
Pore size and position: supports customized porous distribution, irregular pores, and stepped pores
Surface treatment: polishing (mirror/matte), sandblasting, coating (anti reflective, conductive)
What problems can we solve
1. Short lifespan of substitute metal flanges in corrosive environments
In corrosive gas environments such as HCl and Cl ₂, the service life of quartz flanges can be more than 5 times that of metal flanges, significantly reducing replacement frequency and maintenance costs.
2. Avoid pollution and ensure process purity
High purity materials ensure no metal ion contamination during semiconductor and pharmaceutical processes, ensuring product yield and compliance.
3. Achieve reliable sealing in high and low temperature environments
The extremely low coefficient of thermal expansion ensures that the flange maintains sealing during thermal cycling, avoiding the risk of leakage.
4. Meet the integration requirements of complex systems
Support one-stop customization of complex structures such as porous, irregular, and threaded structures, reducing customer secondary processing steps and accelerating equipment assembly efficiency.

Application case (anonymous)
-Case 1: A German photovoltaic equipment manufacturer purchased Ø 180mm quartz flanges for the window sealing of a new type of diffusion furnace door, replacing the original stainless steel flanges, which improved the uniformity of the temperature field inside the furnace by 12% and reduced the product defect rate by 5%.
-Case 2: California Semiconductor Laboratory customized Ø 50mm quartz flange with 8-hole thread for high vacuum molecular beam epitaxy system, achieving sealing requirements of 10 ⁻⁸ Pa level, and has been running stably for 3 years.
-Case 3: Japanese chemical companies use Ø 120mm quartz raised face flanges for connecting chlorine gas recovery pipelines. They have been continuously used for 18 months at 80 ℃ and 0.6MPa without corrosion leakage.
