The Electric Fused Quartz Tube is a clear fused quartz tube manufactured through an electric fusion continuous drawing process. It is designed for applications requiring good optical transparency, high-temperature resistance, chemical stability, and reliable dimensional consistency.
Compared with ordinary glass tubes, fused quartz tubes offer a lower thermal expansion coefficient, higher softening temperature, and better resistance to controlled heating and cooling cycles. These properties make the product suitable for ultraviolet lamps, halogen lamps, photovoltaic equipment, semiconductor-related components, optical fiber parts, laboratory equipment, and other high-temperature industrial applications.
The tube can be customized in outer diameter, wall thickness, length, end finishing, and further processing according to customer drawings or application requirements.
