As a kind of special industrial technology glass made of high-purity silica (SiO2), quartz tube is widely used in various fields because of its excellent physical and chemical properties. According to the size of the tube, quartz tube can be divided into large-diameter quartz tube and small-diameter quartz tube.

I, The difference in tube diameter

Large-diameter quartz tube: The tube diameter is generally more than 100mm, and the maximum can reach 1000mm. This tube diameter design allows large-diameter quartz tubes to support larger flow rates and is suitable for the transportation of large-flow media in the industrial field.

Small-diameter quartz tubes: The diameter is generally less than 10mm, and the minimum can reach 0.1mm. Small-diameter quartz tubes are suitable for microfluidic fields such as chip manufacturing and biosensing due to their small diameter.

II, Physical properties

Thickness and strength: Large-diameter quartz tubes are relatively thick, can withstand higher pressure and temperature, are not easy to scale inside, and have better active cleaning performance. Small-diameter quartz tubes, on the other hand, usually have higher optical transmittance and better etching performance due to their small diameter.

High temperature resistance: The softening point temperature of quartz glass is about 1730 ° C, which can be used for a long time at 1100 ° C, and the maximum temperature for a short time can reach 1450 ° C. Both large and small diameter quartz tubes inherit this excellent high temperature resistance.

Corrosion resistance: Except for hydrofluoric acid, quartz glass hardly reacts chemically with other acids, and its acid resistance is 30 times that of ceramics and 150 times that of stainless steel. Both calibers of quartz tubes exhibit extremely high corrosion resistance.

III, Application field

Large diameter quartz tube:

Solar photovoltaics: As a reflective panel material or packaging tube for solar cells, high transmittance and high stability enable solar cells to maintain high efficiency for a long time.

Semiconductor manufacturing: used for oxygen injection and diffusion in semiconductor chip processing to enhance the performance and stability of semiconductor chips.

Optical fiber communication: carrying optical fibers to maintain urban optical networks as municipal facilities.

Chemical industry: used in high temperature and high pressure reactors, chemical products, and high purity sintering.

Medical: Manufacture of medical devices such as pressure sensors, heat loss devices, meters, and dialyzers.

Small diameter quartz tube:

Microfluidic field: plays an important role in microfluidic technologies such as chip manufacturing and biosensing.

Scientific research: used in laboratory tubular furnaces, chemical reactors, and other equipment for high-temperature experiments and chemical reactions.

IV. Selection and Precautions

When selecting quartz tube, the appropriate caliber should be selected according to the specific application scenario, and its performance should be taken into account, such as high temperature resistance, corrosion resistance, transparency, etc. At the same time, choose a manufacturer with good quality and exquisite craftsmanship to ensure the quality stability and service life of the product.

Customization: Whether it is a large-diameter or small-diameter quartz tube, many manufacturers offer customization services, allowing them to customize different lengths, diameters, and shapes according to their actual needs.

Safety: When using quartz tubes, especially in high-temperature environments, relevant safety regulations should be followed to ensure the normal operation and service life of the equipment.

Large-diameter quartz tubes and small-diameter quartz tubes have significant differences in tube diameter, physical properties and application fields. Large-diameter quartz tubes are widely used in solar energy, semiconductors, optical fiber communications and chemical industry due to their large flow support and excellent high temperature and corrosion resistance. Small-diameter quartz tubes, on the other hand, occupy an important position in the field of microfluidics and scientific research due to their high optical transmittance and etching properties. Understanding these differences can help to choose the right quartz tube according to specific needs, thereby improving the performance and stability of the equipment.
