High Quality Borosilicate Glass Tube Large and Small Diameter Glass Tube for Sale

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 tubes are relatively fragile, so violent collision and excessive stress concentration should be avoided during transportation, installation and use to ensure their safety and service life. Large diameter glass tube plays an important role in many fields with its unique physical and chemical properties. With the continuous progress of technology and the expansion of application fields, the market prospect of large diameter glass tube will be broader.

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 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.
