Frequently Asked Questions
Q What shapes are available for the quartz tubes?
We offer straight tubes, U-shaped tubes, spiral tubes, and fully customized special structures to meet your specific application requirements.
Q What size range do your quartz tubes cover?
Our quartz tubes are available with an outer diameter from 10mm to 500mm, wall thickness from 1mm to 20mm, and lengths from 100mm to 6000mm. Custom dimensions based on customer drawings are also accepted.
Q Do you support vacuum-sealed quartz tube designs?
Yes. We offer vacuum-sealed design options, along with flange connection, closed end, and quartz flange configurations to suit high-precision or vacuum-environment applications.
Q What surface treatment options are available?
We provide three surface treatment options: polished (inner and/or outer surface), frosted, and acid-etched. Each finish is suited to different optical, chemical, or industrial use cases.
Q Can I order quartz tubes with custom structures or drawings?
Absolutely. We accept custom orders based on customer-supplied drawings or specifications. Our team can manufacture special structures and non-standard dimensions to meet unique project demands.
Q Is a quartz flange connection option available for high-temperature use?
Yes. Quartz flange connections are available and are particularly suitable for high-temperature furnace or reactor applications where secure sealing and thermal stability are critical.
