High Quality Large Diameter Fire Polished Quartz Glass Tube Using for Lab Test

Quartz glass tubes are used in the manufacture of halogen, mercury, and xenon lamps, which are commonly used in lighting, stage lighting, and other fields. Due to its high temperature resistance properties, it is used in the manufacture of various heaters such as infrared heaters and ultraviolet heaters. In the laboratory, it is commonly used in tube furnaces, chemical reactors, quartz bet sample tubes and other equipment for high temperature experiments and chemical reactions. As a container for epitaxy, diffusion, oxidation, etc. in the semiconductor production process. Used in ovens, drying equipment, etc., as well as some occasions that require corrosion resistance and high temperature resistance. Daily life such as aquarium heaters, quartz tube foot warmers and so on.

Types of quartz glass tubes

Transparent quartz tubes: with an outer diameter ranging from 1.5mm to 300mm, they are the most common type.

UV Filtering Quartz Tubes: have the function of filtering ultraviolet rays.

Colored Quartz Tubes: Including milky white tubes, pink tubes, etc., with specific colors and uses.

Quartz glass in the ultraviolet to infrared light throughout the spectral band have good light transmission properties, visible light transmission rate of 93% or more, especially in the ultraviolet spectral region, the maximum transmission rate of up to 80% or more. The resistance value of quartz glass is equivalent to 10,000 times that of ordinary glass, which is an excellent electrical insulating material, even at high temperatures, it also has good insulating properties.

The production process of large diameter glass tubes mainly includes batching, melting, forming and annealing. Among them, the forming process is particularly critical, usually using mechanical forming methods such as centrifugal casting, where the molten glass is injected into a high-speed rotating mold, the centrifugal force is used to make the glass cling to the mold wall, and the rotation continues until the glass hardens. This method is capable of producing large diameter, high quality glass tubes.

Large diameter glass tubes are widely used for the storage and transfer of high-viscosity, high-density substances. Its inner wall is smooth and easy to clean and sterilize, making it an ideal packaging material for substances. In industrial production, large diameter glass tubes can be used in separation, reaction and heat transfer devices to meet various process requirements. In architectural design, large diameter glass tube can be used in the design and construction of new energy sources such as solar energy and geothermal energy to improve the efficiency of energy utilization.
