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.

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.
