Wholesale Custom Quartz Furnace Tube for Laboratory & Industrial Use | China Suppliers & Factory Direct Supplier, Factory

Quartz furnace tubes, manufactured from high-purity quartz sand, are essential components for high-temperature heat treatment applications in various industries, including semiconductors, photovoltaics, and new materials. These tubes exhibit exceptional resistance to temperatures exceeding 1200℃, alongside excellent thermal stability and strong chemical inertness. As a crucial element in vacuum furnaces and diffusion furnaces, they provide a controlled environment for wafer processing at elevated temperatures, These high-quality quartz furnace tubes are made from synthetic fused silica (SiO₂ ≥ 99.99%), featuring a low hydroxyl (OH) content of less than 50ppm. As reliable suppliers in China, we ensure that our factory produces top-tier products that meet the rigorous demands of thermal processing equipment. Choose our quartz furnace tubes for unparalleled performance and quality in your high-temperature applications

Frequently Asked Questions
Q What shapes are available for custom quartz tubes?
We offer straight tubes, U-shaped tubes, spiral tubes, and fully customized special structures tailored to your specific application requirements.
Q What size range can be manufactured for quartz tubes?
Our quartz tubes are available with an outer diameter ranging from 10mm to 500mm, wall thickness from 1mm to 20mm, and lengths from 100mm to 6000mm. Custom dimensions can be produced according to customer drawings.
Q Are vacuum-sealed or flanged quartz tube designs available?
Yes. We support flange connections, closed-end designs, quartz flanges, and vacuum-sealed configurations to meet demanding laboratory and industrial requirements.
Q What surface treatment options are offered for quartz tubes?
Available surface treatments include inner and outer polishing, frosted (matte) finish, and acid-etched surface, each suited to different optical, thermal, or chemical application needs.
Q Can quartz tubes be manufactured according to custom drawings or specifications?
Absolutely. All dimensions including outer diameter, wall thickness, and length can be produced based on customer-supplied drawings or technical specifications to ensure a precise fit for your application.
Q What is the difference between polished and frosted quartz tube surfaces?
Polished surfaces (inner or outer) provide high optical clarity and smoothness, ideal for applications requiring light transmission or chemical purity. Frosted surfaces diffuse light and offer a matte appearance, commonly used where reduced reflectivity or improved grip is needed.
