Description
Square and rectangular quartz tube is specified by outer-section and inner-section dimensions rather than OD and ID. It is used where a flat mounting face, non-round process chamber or non-round optical path is required instead of the round-tube standard.
Dimensions
| Parameter | Specification |
|---|---|
| Outer section | Length × width, per drawing |
| Inner section | Length × width, per drawing; follows from outer section minus wall thickness |
| Wall thickness | Per drawing, following the general tube-tolerance principle; thicker wall for larger outer section |
| Corner geometry | Sharp or radiused corner, per drawing |
Production Method
Precision drawn or machined to the target outer and inner section, using the same general fabrication principle as round tube but applied to a non-round die or forming route.
Application
- Non-round process chambers where a flat mounting or viewing face is needed.
- Precision-cut structural or optical components requiring a flat reference surface.
- Custom fixture and equipment components where a round tube’s curved exterior does not fit the mounting geometry.
Material
Standard clear fused quartz; grade options follow the same fused-quartz material system used for Quartz Glass Tubes.
FAQ
Is there a standard square tube size series like round tube has?
No widely published standard size series exists across suppliers. Specify the outer section, inner section, wall thickness and length for quotation.
Should corners be sharp or radiused?
Either can be specified. Radiused corners reduce stress concentration and are generally easier to form cleanly, while sharper corners may be needed for a specific fit or optical geometry.
