Fused quartz tubes and tubing are made by fusing or melting, naturally occurring quartz crystals. The crystals used are of a very high purity. This process takes place at 3632°F or 2000°C. This requires using high temperature furnace. Fused quartz tube and tubing is normally a transparent. The optical and thermal properties of fused quartz is far superior to those of other types of glass. This is due to its very high purity. Fused quartz is used in ultraviolet transmission, clear lens, and other optics for the ultraviolet spectrum. Quartz has low coefficient of thermal expansion. This makes it a useful material for precision mirror substrates. Thermocouple protection tubes are also made from fused quartz. Quartz protection tubes are excellent for molten precious metal applications.
Clear quartz tube is a special industrial technology glass made of silica, which is a very good basic material. Quartz glass has a series of excellent physical and chemical properties, widely use in optical, chemical, semiconductor industrial, liquid crystal, lighting, ect. Heat resistance, light transmission, electrical insulation and chemical stability are very good. Clear quartz tube features the property of high purity and high temperature resistance.
The clear tube that protects a UV lamp is called a sleeve and is made of quartz. The UV clear quartz sleeve is an essential part of any UV water filtration system. This barrier can gradually become coated with mineral deposits and other contaminants, but its' job is to be a barrier between the UV lamp and the water flowing past. Regularly cleaning the UV quartz sleeve of your UV water purifier is important because contaminant buildup on the sleeve can hinder UV transmission and reduce overall system effectiveness. Thorough cleaning and maintenance of the quartz sleeve is recommended every 12 months (best to at the same time you're replacing the UV lamp), and the sleeve should be replaced every 24-36 months. Depending on the quality of your water, you may need to pull out the quartz sleeve and clean it every few months.http://www.fudongquartz.com/fu....sed-quartz-tuebs/cle
