Quartz glass tube is a special industrial technology glass made of silica, with a series of excellent physical and chemical properties, widely used in many fields. When using quartz glass tubes, you need to follow the relevant safety specifications to ensure its normal operation and service life. At the same time, the use of different types and specifications of quartz glass tube may vary, in the actual application of the need to choose according to the specific requirements and conditions of use.

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 softening point temperature of quartz glass is about 1730°C. It can be used for a long time at 1100°C, and the maximum temperature for a short time can be up to 1450°C. In addition to hydrofluoric acid, quartz glass almost no chemical reaction with other acids, and its acid resistance is 30 times that of ceramics, 150 times that of stainless steel, especially at high temperatures, the chemical stability of any other engineering materials are incomparable. The thermal expansion coefficient of quartz glass is extremely small, can withstand drastic temperature changes, the quartz glass will be heated to about 1100 ℃, into the room temperature water will not blow up.

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.
