98mm OD High Purity Quartz Glass Tube Customizable Wall Thickness For Semiconductor Equipment

The 98mm High Purity Quartz Glass Tube is a premium industrial-grade transparent quartz tubing solution manufactured from 99.99% high-purity quartz (SiO₂) raw materials through high-temperature one-piece fusion forming. With an outer diameter of 98mm and fully customizable wall thickness and length, this quartz glass tube is engineered to deliver exceptional performance across the most demanding high-temperature, high-purity, and corrosive fluid handling environments. Its outstanding thermal stability, superior chemical inertness, excellent optical transmittance, and zero metal ion precipitation make it the material of choice for semiconductor fabrication equipment, laboratory reactor systems, lithium battery electrolyte transport lines, photovoltaic thin-film coating machinery, and corrosive chemical processing pipelines. The tube can be easily integrated with compatible flanges, bubbler assemblies, and furnace body components, enabling seamless deployment in gas-liquid transmission, high-temperature vaporization, chemical reagent circulation, and other ultra-clean operational contexts where material purity and mechanical integrity are non-negotiable.

• 98mm Outer Diameter with Full Customization: Standard outer diameter of 98mm with wall thickness adjustable from 1mm to 10mm and length customizable up to 2000mm, providing maximum flexibility for diverse system integration requirements and custom engineering projects.
• Ultra-High Purity Quartz Material: Fabricated from 99.99% pure quartz (SiO₂) with hydroxyl content below 10ppm, ensuring zero heavy metal ion leaching that could contaminate sensitive semiconductor wafers, high-purity reagents, or battery electrolytes during critical manufacturing processes.
• Exceptional High Temperature Resistance: Engineered for continuous long-term service at temperatures ranging from 200℃ to 1100℃ with a softening point of 1683℃. The extremely low coefficient of thermal expansion provides outstanding resistance to thermal shock, preventing cracking or structural failure during rapid heating and cooling cycles.
• Superior Chemical Corrosion Resistance: Exhibits remarkable chemical inertness against a comprehensive range of aggressive media including concentrated strong acids, strong alkalis, and even hydrofluoric acid. This corrosion resistance far exceeds that of ordinary borosilicate glass and stainless steel tubing, making it irreplaceable for harsh chemical processing environments.
• High Optical Transmittance Across UV-Visible Spectrum: Delivers excellent light transmittance performance in both ultraviolet and visible wavelength ranges, making the tube ideally suited for UV disinfection systems, photocatalytic reaction vessels, optical sensing equipment, and scientific observation experiments that demand crystal-clear optical clarity.
• Versatile Secondary Processing Capability: Supports a wide range of post-formation processing operations including precision cutting, slotting, drilling, flame polishing, end forming, and fusion welding. This allows the standard tube to be further fabricated into complex instrument components, custom assemblies, and specialized fittings according to exact customer specifications.
• Excellent Mechanical Strength and Longevity: With a density of 2.2 g/cm³, Mohs hardness of 5.5-6.5, and tensile strength of 48.3 MPa, the tube maintains robust mechanical integrity under sustained thermal and mechanical stress, ensuring reliable long-term operational performance with minimal maintenance requirements.

The 98mm High Purity Quartz Glass Tube delivers exceptional value across a diverse range of high-technology industrial sectors. In semiconductor manufacturing, it serves as a critical component for chemical vapor deposition (CVD) gas delivery lines, diffusion furnace process tubes, and wet etching chemical transport conduits where ultra-high purity and contamination-free operation are absolute prerequisites. For the lithium battery and new energy sector, the tube provides reliable high-purity electrolyte and solvent transfer pathways in automated cell production lines, with zero metal ion dissolution that could otherwise compromise battery performance and safety. In photovoltaic cell manufacturing, it functions as a durable coating gas delivery tube within PECVD and diffusion equipment, withstanding sustained elevated temperatures and corrosive process gases including silane and phosphine. Laboratory and scientific research facilities utilize the tube for high-temperature tube furnaces, chemical vapor transport experiments, catalytic reaction studies, and optical spectroscopy sample cells where precise temperature control and optical access are simultaneously required. Chemical processing plants employ the tube for aggressive media transfer including concentrated sulfuric acid, nitric acid, hydrochloric acid, and mixed acid systems where metallic piping would rapidly corrode and fail. The tube is also widely integrated into water treatment and environmental monitoring equipment for UV sterilization chambers, ozone generation modules, and online water quality analyzer flow cells. Additional applications include pharmaceutical intermediate synthesis reactors, food and beverage processing hygienic transfer lines, fiber optic preform manufacturing support tubes, and specialized glassblowing and scientific glassware fabrication where the combination of high purity, thermal stability, and workability is essential for producing precision components.

Every 98mm High Purity Quartz Glass Tube undergoes rigorous quality inspection prior to shipment, including dimensional accuracy verification with precision calipers, visual inspection for surface defects and inclusions under controlled lighting, and material purity certification traceable to raw material batch records. Products are carefully wrapped in multiple layers of protective bubble padding and high-density foam cushioning, then securely placed in reinforced export-grade corrugated cartons or sturdy wooden crates depending on order quantity and tube dimensions.
