As a professional manufacturer specializing in infrared heating field, Luverre Quartz is committed to providing fused silica tubes with purity up to 99.99%. From infrared heating element packaging to rigorous semiconductor processes, our quartz tubes provide a solid material guarantee for global industrial heating and optical applications with their excellent temperature resistance, extremely low thermal expansion coefficient, and excellent spectral transmittance.

Frequently asked questions about infrared high-purity fused silica tube (FAQ)

Q: My infrared heating device often bursts due to thermal shock when using ordinary glass tubes. How can I solve this problem?

Answer: Choose our high-purity fused silica tube. Its extremely low coefficient of thermal expansion (5.5 × 10 ⁻⁷/℃) enables it to withstand intense alternating cold and heat without breaking, significantly improving equipment service life and on-site safety.

Q: What should I do if impurities precipitate from the pipe during high-temperature heating and contaminate my product?

Answer: Our quartz tube is made of high-purity silicon dioxide raw material, with extremely low metal impurity content (<20ppm). Maintain chemical stability even at high temperatures of 1200 ℃, ensuring a clean and pollution-free heating environment, especially suitable for semiconductor and food grade drying lines.

Q: Can I customize a specific size and shape of irregular quartz tube to match the equipment?

Answer: Absolutely possible. We provide flexible customization services, supporting various diameters, lengths, wall thicknesses, as well as special-shaped processing such as bends and heads, to meet the personalized spatial layout requirements of your equipment.

Core advantage: Why are we your preferred supplier for infrared quartz tubes

1. Ultimate material purity and spectral performance

Our fused silica tube has controllable hydroxyl content and extremely low impurity content. This means that in infrared application scenarios, the absorption of infrared radiation by pipes is minimal, allowing for maximum energy transfer to the heated object. This not only saves energy but also enables rapid reaching of the process temperature.

2. Excellent temperature resistance and thermal shock stability

Infrared heating is often accompanied by instantaneous high temperature shocks. Our product has the characteristics of high softening point and no deformation at high temperatures. Even under harsh working conditions, repeated temperature fluctuations will not produce small cracks, ensuring that the infrared filament or heating element inside the package is perfectly protected.

3. Rich specifications and deep customization capabilities

We are not limited to standard round pipes. For different heating equipment designs, we can provide:

Optics and size customization: Adjust the thickness and transparency of the pipe according to the infrared radiation wavelength you need.

Irregular processing: U-shaped pipes, bent pipes, irregular quartz sleeves with sealing or openings.

Precision Grinding: For applications that require high-precision sealing, we provide end face grinding services to ensure fit tolerances.

4. Addressing the core pain points of the industry

Pain point: Imported pipes have long lead times and high costs.

Solution: We have a mature supply chain and experience in large-scale production. While ensuring quality meets international standards, we significantly shorten delivery cycles and reduce your procurement costs.

Pain point: Short circuit caused by condensation water under low temperature conditions.

Solution: By using special surface treatment processes such as sanding/whitening, radiation reflection can be effectively reduced, making heat more uniform and reducing the risk of local condensation.

Customer Application Cases

Case 1: A high-end printing machinery manufacturer in Europe (solving the problem of instantaneous ink drying)

Background of demand: The high-speed flexographic printing machine produced by this customer requires instant drying of water-based ink at high speeds (300 meters/minute). The previously used ordinary infrared sleeve had low thermal conductivity and uneven heating caused ink bubbles.

Our solution: We provide it with a milky white semi transparent infrared quartz tube. This type of pipe can convert infrared radiation energy into specific bands of thermal energy, which is uniformly radiated onto the printing substrate.

Final effect: After using our quartz tube, the drying efficiency was improved by 35%, completely solving the "false drying" phenomenon of ink surface crust and internal non drying. All new models from the customer will be designated to use our customized pipes.

Case 2: A certain photovoltaic enterprise (core components of PECVD coating equipment)

Requirement background: The PECVD (Plasma Enhanced Chemical Vapor Deposition) equipment used in the manufacturing process of photovoltaic cells requires quartz tubes as chamber protection tubes for process gas reactions. Ordinary quartz tubes are prone to pitting corrosion under plasma bombardment, and metal impurities can contaminate silicon wafers, leading to a decrease in cell efficiency.

Our solution: We have delivered a high-purity low hydroxyl fused silica tube to strictly control the bubbles and particle size to ensure its corrosion resistance and dielectric strength in the plasma environment.

Final effect: The service life of this batch of quartz tubes has been extended by 2 times compared to the previous supplier's products, and the coating uniformity has been improved, helping customers reduce the frequency of equipment downtime and maintenance.
