    ❓ Frequently Asked Questions

    Q: What shapes are available for the quartz tubes?
    A: We offer straight tubes, U-shaped tubes, spiral tubes, and fully customized special structures to meet your specific application requirements.
    Q: What size range is supported for custom quartz tubes?
    A: Outer diameters range from 10mm to 500mm, wall thickness from 1mm to 20mm, and lengths from 100mm to 6000mm. All dimensions can be produced according to your drawings.
    Q: Are vacuum-sealed quartz tubes available?
    A: Yes. We provide vacuum-sealed design options, along with flange connection, closed end, and quartz flange configurations to suit various industrial needs.
    Q: What surface treatment options are offered?
    A: Surface treatments include polishing (inner and/or outer surfaces), frosted finish, and acid-etched surface, depending on your application and optical requirements.
    Q: Can I order quartz tubes based on my own technical drawings?
    A: Absolutely. All specifications including shape, size, features, and surface treatment can be fully customized according to customer-supplied drawings and technical requirements.
    Q: What is the difference between frosted and acid-etched surface treatments?
    A: Frosted surfaces are mechanically processed to create a uniform matte finish, while acid-etched surfaces use chemical treatment to achieve a fine, even texture — both reduce light reflection and improve diffusion for specific optical or industrial applications.
