clear quartz tube with large diamter

SiO2 content of raw materials: 99.9% fused quartz tube Diameter from 80--250mm Φ 200-320 mm super large OD clear fused quartz tube is mainly used in photovoltaic diffusion furnace, quartz tank quartz plate, and fine chemical pipes line, Φ 15-200 mm large OD clear quartz tube is our major products, which is widely used in semiconductor, light sources, chemical tube and telecom.The UV-stop quartz tube can 100% stop the transmission of middle and short wavelength, and can prevent most of long wavelength radiation. It can be used to make quartz halogen lamp, gas discharge and other UV lamp-house. This cerium-doped quartz tube can effectively prevent all radiation of UV to harm the body. Ozone Free quartz tube blocks wavelength<220 nm, while transmit over 90%in 253.7nm. It's used for germicidal lamp. And the twin quartz tube is used for the coating heater of the luxury cars. We have produced Φ 10-80mm transparent quartz tube that has characteristic of high purity, good transition, no airline, and few bubbles.And widely used in the quartz ware, laser making, fiber-optical, optics ware and semiconductor industry. Our quartz products have the typical characteristic of high purity, good temperature, and long life to use and so on
