This is clear fused quartz glass tube available as continuous machine drawn and automatic controlled tubing. This glass had the typical characteriastics of high purity, good spectral transmission, well controlled dimension and lower oh and so on. It serves as the first choice of heat resistant material for halogen lamps, mercury lamps, metal halide lamps and other quartz lamps. This glass can be supplied in the range of 3-260mm outside diameter, 0.5-8.0mm wall thickness and 10-3000mm length. Exhaust tubes with good cpk are suitable for high-speed streamline production. And further processing of trim cutting, fire polishing, bending and pinching and etc. Can be done according to the requirement of customers. Oh-content can be controled within 20ppm\15ppm\10ppm\5ppm\2ppm according to the requirement of customers.

Quartz glasss tube/Infrared milky quartz tube with as below advantage, and be the best choice for infrared heating element. 1. With Infrared radiation, and the transmissivity of infrared is arrived to 70-75% 2. With out surface coating and infectant, is a excellent chemic products 3. With high heat stability and high temperature resistant. 4. Can be make by various shaped, and ametabolic long using. 5. Heating temperature selective, as well unchangeable radiation ability in long term. 6. Structure reasonable 7. Make used of convenient. OD10mm*1mm*2500mm OD10mm*1mm*2250mm OD23mm*20mm*2250mm.
A quartz tube is one kind of basal material. It's main component is silicon dioxide.It has series of excellent physical and chemical capabilities, such as heat resisting, corrision resisting, good heat stability and so on. Because of having above excellent physical and chemical properties, they are widely used in dlectric lamphouse, semiconductor, light communications, martial industry, metallurgy, electric power and so on. Spec can be controlled by customers' demand.
With the adoption of distinctive technique, our opaque quartz glass tube has its typical characteristics of good visual aspects and stable physical &chemical properties. It serves as material of infrared heating for heaters, micro-wave oven, electrical baking oven, car paint baking, sterilization container and other consumptive and industrial infrared application. Further processing of trim cutting, bowing, fire-polishing can be done according to the demanding of the customers Standard export packing avoid breaking.
Clear glass tube is industrial use standard melting clear quartz glass tube, SiO2 is greater than 99.9%, good stability, corrosion resistance, spectral through rate is high, the most of all, price is reasonable. Clear glass tube mainly used for electric light industry, parts used in semiconductor, optical fiber and chemical industry. Quartz glass tube did not take off the hydroxyl used in tungsten halogen lamp, heater, chemical industry, equipment high temperature resistant products, hydroxyl quartz glass tube ( slower hydroxyl) used for high-pressure mercury lamp, UV lamp. The vacuum hydroxyl quartz glass tube (low hydroxyl quartz glass tube) used for Blister of metal halide lamp. We can produce diameter between 1 mm-300 mm of all kinds of hydroxyl quartz glass tube, hydroxyl can be controlled in less than 20 PPM, 10 PPM, 5 PPM.
Milky (opaque) quartz (silica SiO2) glass tube surface is smooth, white degree (purity) is high, and internal quality is stable, corrosion resistance, it can convert near-infrared to far-infrared. Therefore, milky quartz tube is the first choice of material for space heater, microwave oven, electric oven, alexipharmic ark, strong acid heater and others.
