Specification :

Large-diameter quartz tube: large diameter quartz tube is a special type of transparent quartz tubes. Large diameter quartz tube with high temperature corrosion resistance, thermal stability, good transparency and good electrical insulation and a series of excellent physical and chemical properties, is widely used for special metal smelting molds, precision chemical pipelines, electric furnace tubes, diffusion tubes, cleaning tanks and production equipment, square cylinder, quartz plate and so on. Our company firstly introduced the latest technology of large diameter quartz tube equipment-- Asia' s single largest tungsten and molybdenum 760mm crucible, 350mm diameter big inch quartz tube can be directly turned out, which refreshed the maximum size of internal made though melting method. Large diameter quartz tube has been declared as a patent of our company. In production, we input high purity quartz powder as raw material, removal of any senior technical staff monitor the entire process to ensure product quality, the large diameter quartz tube turned out contains silica purer than 99.98% . With lesser bubble gas line and magazine content, it can also be further cut to the expansion of large-diameter quartz tube plastic tube to meet the semiconductor, photovoltaic and other high-tech industry, application requirements, and gradually replace the imported large diameter quartz tube. Large diameter quartz tube enhanced competitiveness in international markets by accessing to Japan and South Korea, Europe and America, Taiwan and other countries and regions and gained the recognition and praise. 300mm diameter or more diameter quartz tube is another high-tech products, followed red, yellow, blue and grey colorful quartz tube developed by our company independent research. Our company invested a lot of manpower, financial and material resources, through unremitting efforts, repeated tests, and finally the successful development of mass production of Large-diameter quartz tube in early 2011. Our Company with leading technology has a very high price advantage in the big inch quartz glass industry, we warmly welcome guests to our site visit, make more valuable advice, and seek common innovation and development. dongxinquartz( at) 163( dot) com
