Frequently Asked Questions

What are the main differences between Clear and Milky Quartz Tubes?

We provide high-purity Clear Fused Quartz Tubing (SiO2 > 99.99%) for applications requiring excellent optical clarity and heat resistance. Our Milky White/Opaque Quartz Tubes are specially designed for infrared heating and furnace insulation, offering superior thermal barrier properties compared to standard clear glass.

Can you handle custom fabrication based on technical drawings?

Yes, customization is our core strength. Beyond standard Quartz Glass Tubing, we offer precision CNC machining, bending, flanging, and sealing. Whether you need a small prototype or Large Diameter Quartz Tubes with complex structures, our engineering team ensures every piece matches your specific CAD drawings.

What tolerances can I expect for your quartz glass products?

For standard High Purity Quartz Tubes, we maintain a tight Outside Diameter (OD) and Wall Thickness tolerance of ±0.1mm to ±0.2mm. For specialized industrial furnace liners, we can adjust tolerances based on your project’s precision requirements to ensure a perfect fit for your equipment.

How do you ensure the safety of quartz tubes during global shipping?

Quartz is fragile, so we use export-standard wooden crates and shock-absorbing foam. For Thick Wall Quartz Tubes or long-length shipments, we provide reinforced packaging. We have extensive experience in global logistics, ensuring your order arrives intact at your facility.
