Valiant specializes in manufacturing large diameter quartz tubes that meet the highest standards of purity, thermal stability, and dimensional precision. Engineered from high-purity fused silica, our large-diameter tubes are ideal for semiconductor, solar, industrial heating, and chemical processing applications where scale, reliability, and performance are critical.
Grade 510: Large Diameter Tubes
Extra-Wide Dimensions
Available in diameters 800 mm or greater with customizable wall thicknesses and lengths to suit process requirements.
High-Purity Fused Quartz
Made from 99.995%+ SiO₂ to ensure ultra-low contamination for cleanroom and high-purity environments.
Excellent Thermal Performance
Withstands continuous temperatures at 1100–1200°C with outstanding thermal shock resistance, ideal for high-temp furnace and reactor systems.
Smooth, Transparent Surface
Optical-grade finish (optional) for applications requiring light transmission or visual inspection.
Durability & Dimensional Stability
Structural integrity maintained under mechanical and thermal stress, as a result, commonly utilized in vacuum or high-pressure environments.
