There are many types of quartz tube, can be roughly divided into the following:
Quartz tube, quartz thick wall tube, double quartz tube include a variety of transparent, pearly, purple quartz tube, UV, UV sterilization lamp outer casing, submersible germicidal lamp quartz water sleeve, and the light of benzyl chloride special quartz glass tube and so on, transparent quartz glass tube diameter 2-248mm, wall thickness 0.5-8mm, 10-2000mm even melt off cavity quartz tube, metal halide lamp special low hydroxy quartz tube, ozone, UV filter tube tube. Ordinary continuous melting tube SiO2 is above 99.6, geometric size, chemical stability, thermal stability, thermal denaturation and anti crystallization properties, optical transmittance reaches above 90%; dehydroxylation tube hydroxyl below 10ppm, after processing, hydroxyl reach below 5ppm; pearl tube is a new industry and milky tube art products, pipe surface if Pearl's surface, used in the manufacture of heating tube, far infrared tube.
The glass tube is special industrial technology glass made by silicon dioxide, is a very good base material. Quartz glass has a series of excellent physical, chemical properties: high temperature resistance, corrosion resistance, good thermal stability, good light transmission performance, good electrical insulation properties, quartz tube with the excellent physical and chemical properties, so it is widely used in various fields of electric light source, semiconductor, optical communication, military industry, metallurgy, building materials, chemical, machinery, electric power, environmental protection etc..
