Company: Donghai Shengda Quartz Products Co., LtdCertification: ISO 9001, ISO14001, OHSAS18001Advantage: cost price controlled well, high precision, good quality.Product:quartz sleeve, custom quartz tube, custom quartz tube, quartz glass tube, quartz sleeve for water purification, clear quartz tube, twin quartz tube, quartz glass, quartz tubing, quartz glass tube, silica tube, transparent quartz tube, quartz tube , clear fused quartz glass, quartz glass tube, large diameter quartz tube,large quartz tube, low Hydroxyl quartz tube / quart tubing, uv stop quartz tube, ultraviolet tube,uv block quartz tube, uv quartz tube, quartz glass tube, quartz tubingOur clear fused quartz glass tubes are produced with the advantaged continuous melting method and controlled by automatic control system. These tubes advantages are high purity, good spectral transmission, well controlled dimension and low OH, etc. They’re the best heat resisting material for lamps like: halogen lamps, mercury lamps, metal halide lamps, etc. We can produce the tubes within a very large diameter rang: OD 3-80mm, thickness 0.6 – 2.0mm , length 800- 2400mm. Exhaust tubes with good CPK and are suitable for high-speed streamline producing. We also can apply some further processing like trim cutting, fire polishing, bending, pinching, grinding and others according to customers’ requirements. We also can control our tubes OH content within 20ppm\ 15ppm\10ppm\5ppm\2ppm as your special needs.Dimensional Tolerance Range of OD OD OD Thickness Siding Out of Round Bow/1220mm ≤ 6mm ± 2.0% ± 10% 12% 2.0% 2.5mm 6.00-15.00mm ± 1.25% ± 8% 10% 1.5%2.5mm 15.00-20.00mm± 1.25% ± 10%15%1.5% 2.5mm20.00-25.00mm± 1.25% ± 10%15%1.5%2.5mm 25.00-30.00mm ± 1.35% ± 12%15% 1.5% 2.5mm 30.00-80.00mm± 1.5% ± 14% 15% 2.0%2.5mmPhysical properties: Density Density 20 °C kg * m-3 (× 103) 2.2 Coefficient of Thermal Expansion:25-300 °C °C -1 (× 10-6) 0.56 Softening Point: (°C) 1710 Annealing point: (°C) 1230 Transformation point Strain point (°C) 1140 Young's Modulus: (Pa) 7.3 × 105Application:The product is widely used: halogen lamps, mercury lamps, single-ended lamp, automobile lamp, stage lamp, thermocouple, copiers lights, water treatment lamp casing, all kinds of quartz vessels, pipelines and other fields.
