This is clear fused quartz glass tube available as continuous machine drawn and automatic con-trolled tubing. This glass has the typical characteristics of high purity, good spectral transmission, well controlled dimension and lower OH and so on. It serves as the first choice of heat resistant mate-rial for halogen lamps, mercury lamps, meal halide lamps and other quartz lamps. This glass can be supplied in the range of 3-80mm outside diameter, 0.6-2.0mmwall thickness and 800-2400mm length. Exhaust tubes with good CPK are suitable for high-speed streamline production. And further process-ing of trim cutting, bending and pinching can be done according to the requirement of customers. OH-content can be controlled within 20ppm\15ppm\10ppm\5ppm\2ppm according to the re-quirement of customers.
The detailed dimensional tolerance and technical data can be found in table Ⅰ , table Ⅱ , table Ⅲ , table Ⅳ , table Ⅴ .
