Frequently Asked Questions
What shapes are available for the quartz tubes?
The quartz tubes are available in straight tube, U-shaped tube, and spiral tube forms. Custom special structures can also be manufactured based on specific requirements.
What size range do the quartz tubes come in?
The outer diameter ranges from 10mm to 500mm, with wall thickness from 1mm to 20mm. Lengths can be produced from 100mm up to 6000mm, all manufactured according to customer drawings.
Is a vacuum-sealed design available?
Yes. Vacuum-sealed designs are available, along with flange connection, closed end, and quartz flange options to suit various application needs.
What surface treatment options are offered?
Three surface treatment options are available: polished (inner and/or outer surface), frosted, and acid-etched. The choice depends on the intended use and optical or cleanliness requirements.
Can I order quartz tubes with custom specifications?
Yes. All dimensions including outer diameter, wall thickness, and length are produced according to customer drawings. Custom shapes and special structural configurations are also supported.
What connection types are supported for quartz tube assemblies?
Supported connection types include flange connection and quartz flange, as well as closed-end configurations. These options make the tubes suitable for sealed systems, laboratory setups, and industrial process equipment.
