Product Description
heat resistant quartz glass tubes,quartz heating tube,quartz tube
Quartz glass has a series of excellent physical and chemical properties, high temperature resistance, anti-corrosive, good light transmission, good electrical insulation properties. Because of the excellent physical and chemical properties, it is widely applied in electric light sources, semiconductor, optical communications, military, metallurgy, building materials, chemical, mechanical, electrical, environmental protection ect, such as manufacturing halogen lamp, mercury lamp, metal halide lamp, light tube of copy machine, electric light source products stage lighting as well as prodducing chemical pipelines and heat-resistant utensils, etc.
We produce different sizes and kinds of quartz tubes, such as thick wall quartz tubes, large diameter quartz tube, quartz twin tube, u-shape tube, C shape tube, quartz capillary tube, perforated tube, four holes tube, one end closed tube, quartz test tube, heat resisting quartz tube, corrosion resisting quartz tube, and other special shaped tubes according to customers' design.
