Transparent Quartz Glass Tubes For Heater Using

Product Features:

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 3-400mm, thickness wall 0.7 – 10.0mm , length maximum 3000mm.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.
