Opaque milky white quartz tube, also known as milky white quartz glass tube, is a professional functional pipe made of high-purity quartz sand and produced by special processes to generate dense small bubbles in the tube wall. Its unique opacity results in a transmittance of less than 8% in the visible light band and an emissivity of over 90% in the far-infrared 5-13 μ m band. With excellent high temperature resistance (up to 1200 ℃ for long-term use), rapid heating and cooling stability (800 ℃ to 20 ℃ water cooling cycle without explosion), and extremely strong acid and alkali corrosion resistance, it has become the core component in the fields of heating and drying, semiconductor equipment, and medical therapy equipment in the international market.

Opaque milky white quartz tube solves your core procurement pain point

Q: My product needs to be quickly heated up in a closed space for drying, but the transparent tube I used before had low thermal efficiency and emitted bright light. What should I do?

Answer: Our opaque milky white quartz tube can perfectly solve this problem. It transforms the heat conduction mode from "transmission" to "radiation" through the layer of tiny bubbles on the tube wall, converting electrical energy into high-energy far-infrared radiation and significantly improving heating efficiency. At the same time, the milky white appearance softens the glaring visible light, making the working environment safer and more comfortable.

Q: I need to customize a batch of heating tubes that are resistant to strong acid corrosion and high temperature for heating chemical liquids. Can you do it?

Answer: Absolutely possible. We provide customized services based on pictures, which can select and seal pipes for strong acid environments such as aqua regia and sulfuric acid. Our opaque quartz tube has a SiO ₂ content of over 99.5%, and in addition to hydrofluoric acid and hot phosphoric acid, it has excellent acid and alkali resistance, ensuring long service life under harsh working conditions.

Q: When purchasing quartz tubes, I am most afraid of mismatched specifications. If I want a special specification with an outer diameter of 32mm, a wall thickness of 4mm, and a length of 1370mm, can I do it?

Answer: This is precisely our core advantage. As a custom factory, we are not limited to stock standard parts. Whether you need a large diameter (such as an outer diameter of 60mm or more), special wall thickness, or irregular processing (bending, sealing, sanding), we can meet your customized needs through precise cutting, burning, and forming processes.

The core advantages and application scenarios of opaque milky white quartz tubes

Excellent far-infrared radiation performance: a powerful tool for industrial heating and drying

The evenly distributed tiny bubbles inside the product greatly increase the scattering area of thermal radiation, making it highly efficient in a specific wavelength range.

-Application case: In the food processing and paint curing industries, utilizing its far-infrared emissivity of over 90%, it can penetrate the interior of the heated object, achieving drying from the inside out, not only fast but also good uniformity.

Extreme temperature stability: guarantee for semiconductors and harsh industrial environments

The softening point temperature of the product is as high as 1730 ℃, and the coefficient of thermal expansion is extremely low (5.4 × 10 ⁻⁷/℃), with excellent thermal stability.

-Application case: Used as a furnace tube in semiconductor diffusion furnaces, it can withstand frequent temperature rise and fall operations at high temperatures, is not easily deformed or exploded, and effectively protects the purity and stability of the wafer process.

Flexible customized dimensions and geometric accuracy

In order to match the interface requirements of different devices worldwide, we provide high-precision size customization services.

-Customization scope:

-Outer diameter (OD): 4mm -350mm (or even larger)

-Wall thickness: 1.5mm -15mm

-Length: 20mm -5000mm

-Tolerance control: The outer diameter tolerance can be controlled within ± 1.5%, and the bending degree should not exceed 2 ‰ of the pipe length.

-Deep processing: It can perform processes such as bending, sealing, grinding, punching, and rounding.

Customer application case sharing

Case 1: A large food drying equipment manufacturer in Southeast Asia

-Requirement: The customer originally used stainless steel heating tubes, which had problems with slow heating, high energy consumption, and uneven material drying due to local overheating. They need a heating element that can improve drying efficiency and reduce defect rates.

-Solution: We have customized large-diameter (OD35mm) spiral opaque milky white quartz heating tubes for our customers. By utilizing its high far-infrared emissivity characteristics, the heating module of the device has been redesigned.

-Final effect: After the equipment upgrade, the heating time inside the drying chamber was shortened by 30%, and the penetration power of far-infrared enabled synchronous drying of seafood inside and outside, resulting in a yield rate of over 98%. The customer's subsequent orders have shifted from standard pipes to more complex customized U-shaped pipes.

Case 2: A high-end experimental instrument company in Europe

-Requirement: Develop a new generation of high-temperature acid purification instrument, requiring a transparent observation window and heating chamber that can withstand high temperatures (long-term above 1000 ℃) and resist corrosion by concentrated nitric acid.

-Solution: Provide high-purity opaque quartz tubes as heating chambers, coupled with precision machined frosted interfaces.

-Final effect: After 500 hours of continuous high-temperature acid corrosion testing, the instrument showed no corrosion marks on the pipe wall and no contamination of the sample by precipitates. The customer praised our materials for "redefining the standard of laboratory chemical refractory materials".
