Our 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.
