Wholesale Large Diameter Clear Quartz Furnace Tube 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.

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.

Large diameter glass tube, as a special glass product is a relatively large diameter glass tube. Its diameter is usually more than 100 mm, and its length can be customized according to specific needs. Large diameter glass tubes are characterized by high transparency, excellent thermal insulation, good corrosion and heat resistance, etc. These characteristics make it play an important role in many fields.

Quartz glass has a very low coefficient of thermal expansion, high temperature resistance, excellent chemical stability, excellent electrical insulation, low and stable ultrasonic delay properties, the best UV-visible spectral properties and visible and near-infrared spectral properties, as well as higher mechanical properties than ordinary glass.
