Quartz vacuum double-layer tube
Quartz vacuum double-layer tube is a special tubular structure made of high-purity quartz glass, which is nested with inner and outer layers of quartz tubes and forms a circular cavity between the two layers. This unique structural design enables it to perform well in extreme environments such as high temperature and vacuum, making it an important material for scientific research, industry, and high-end manufacturing. 1
Main features:
Double layered nested design: consisting of an outer quartz tube and an inner quartz tube embedded within it, forming a closed annular cavity between the two layers. This design ensures the stability of the inner pipe fittings and provides space for special functions such as water cooling and insulation.
Ultra high purity: The purity of quartz tubes usually reaches SiO ₂>99.9%, with a colorless and transparent surface. The purity can be customized according to requirements (hydroxyl content 1-160ppm) to ensure optical performance and chemical stability.
Excellent physical properties: melting point up to 1750-1780 ℃, extremely low coefficient of thermal expansion (about 5.5 × 10 ⁻⁷/℃), excellent thermal stability. Even if quickly immersed in room temperature water after heating at 1100 ℃, there will be no cracks, gaps, or collapse.
Excellent chemical inertness: except for hydrofluoric acid, it is almost resistant to corrosion from all acids, bases, and organic solvents, making it particularly suitable for use in harsh chemical environments.
Sealing and insulation performance: The double-layer structure combined with precision sealing components (such as stainless steel flanges and fastening rings) can form an ultra-high vacuum environment or insulation barrier, ensuring that internal experiments or processes are not affected by external interference.
Quartz vacuum double-layer tubes can be classified into transparent, frosted, and milky white types based on transparency, meeting different optical and concealment requirements. Its high hardness (Mohs hardness 7) and low density (about 2.2g/cm ⊃3;) also give it advantages in mechanical processing and installation.
Main application areas
Quartz vacuum double-layer tubes have been widely used in multiple high-tech fields due to their unique properties
1. High temperature experiment and industrial heating equipment
In the manufacturing of electric heating products, quartz vacuum double-layer tubes can be used as heating tubes, electric heating tubes, and core tubes for electric ovens. Its high temperature resistance and thermal stability enable it to withstand high-temperature working environments for a long time, while the double-layer structure can effectively prevent heat leakage and improve energy utilization efficiency. In the field of chemical engineering, it can be used as a cooling device for high-temperature acid resistant gases, or for storing chemical reagents such as distilled water, hydrochloric acid, sulfuric acid, etc.
2. Vacuum and Optical Systems
Double layered tubes combined with precision sealing components can create ultra-high vacuum environments, which are widely used in semiconductor manufacturing, vacuum observation windows, vacuum reactors, and vacuum thermostats. Its optical transparency makes it an ideal material for laser vacuum observation windows and ultraviolet/infrared optical components, used in precision optical instruments such as gas detection sealed gas chambers and liquid detection sealed gas pools.
3. Scientific research and special experimental equipment
In physics and chemistry experiments, quartz vacuum double-layer tubes are commonly used to manufacture precision instruments such as alkali metal atom chambers, reference chambers, and vacuum observation windows. Its surface is smooth, with strict dimensional tolerances, and special processing such as half surface gold plating can be carried out according to experimental requirements. The double-layer structure can also provide additional safety protection to prevent leakage of experimental substances or external contamination.
4. Military and Aerospace Industry
In the military industry, quartz vacuum double-layer tubes can be used to manufacture extreme environmental components such as rocket nozzles, spacecraft heat shields, and observation windows. Its radiation resistance, high voltage resistance, and corrosion resistance make it an ideal choice for special military equipment.
5. Medical and Biotechnology
In medical equipment, it can be used to manufacture light source tubes with special wavelengths, sterilization lamps in disinfection equipment, etc. In biological experiments, it can be used to construct a sterile vacuum environment, such as metal hard tube endoscope sealing sleeves and glass gas pools.
Customized service
As a special material, the specifications and performance of quartz vacuum double-layer tubes often need to be customized according to specific application scenarios.
1. Customized parameter range
Size specifications: Diameter, wall thickness, length, and other dimensions can be customized according to customer needs, and the ratio of inner and outer dimensions of double-layer pipes can also be flexibly adjusted.
Transparency: Provides multiple optical performance options such as transparency, matte, and milky white.
Purity and hydroxyl content: The purity of SiO ₂ can reach over 99.95%, and the hydroxyl content can be customized within the range of 1-160ppm to meet different optical and chemical requirements.
Special processing: supports surface treatments such as half face gold plating, etching, bending, as well as special structural designs such as spiral tubes and double hole tubes.
Purchase precautions
Clarify application scenarios: Determine the requirements for temperature, vacuum degree, optical performance, and chemical environment based on the usage environment, and choose appropriate purity, transparency, and size specifications.
Professional advice: Due to the diverse specifications of quartz tubes, it is recommended to contact us in advance and choose the most suitable model or propose customized requirements based on actual needs.
Pay attention to sealing performance: If used in vacuum systems, it is necessary to confirm whether the material and sealing grade of the sealing components (such as stainless steel flanges) of the double-layer tube meet the requirements.
Minimum order quantity: No requirements.
Quartz vacuum double-layer tube is a powerful and versatile special material, and its excellent high temperature resistance, corrosion resistance, and vacuum compatibility make it indispensable in multiple high-end fields.
