Transparent quartz plug tube
Q: I need a transparent sealing component that can maintain stability in high temperature environments. What is the solution?
Answer: Transparent quartz plug tube - made of high-purity quartz material, capable of withstanding high temperatures above 1200 ℃, providing excellent chemical stability and transparency.
Q: My production process requires customized sizes of pipeline sealing components. How can I achieve this?
Answer: We provide full-size customization services, ranging from 2mm to 200mm in diameter and 10mm to 2000mm in length, all of which can be accurately processed according to your equipment parameters.
Q: How to prevent corrosive media from corroding the connection parts in laboratories or industrial equipment?
Answer: Quartz plug tubes have excellent acid and alkali corrosion resistance, making them particularly suitable for sealing applications in harsh environments such as semiconductors, photovoltaics, and chemicals.
Transparent quartz plug tube is a tubular sealing component made of high-purity fused silica (SiO ₂ content ≥ 99.99%). Both ends can be precision ground to ensure perfect cooperation with various quartz glassware, metal flanges or special equipment.

Key performance parameters
-Temperature resistance range: -50 ℃ to+1200 ℃ (can withstand 1450 ℃ in the short term)
-Thermal expansion coefficient: 5.5 × 10 ⁻⁷/℃ (only 1/15 of ordinary glass)
-Transmittance: Visible light band ≥ 92%, maintaining excellent transmittance from ultraviolet to infrared band
-Chemical stability: Resistant to most acid-base corrosion except hydrofluoric acid and hot phosphoric acid
-Surface accuracy: The roughness Ra of the grinding area is ≤ 0.2 μ m, ensuring no leakage in the seal
Product application areas
1. Semiconductor manufacturing industry: observation window sealing for diffusion furnaces and CVD reaction furnaces
2. Photovoltaic industry: Transparent sealing components for polycrystalline silicon ingot furnaces and cleaning equipment
3. Laboratory equipment: High temperature reaction kettle, spectrometer sample chamber, vacuum system connection

-Extremely low coefficient of thermal expansion ensures that it does not rupture during drastic temperature changes
-The thermal shock resistance far exceeds that of ordinary glass and most ceramic materials
2. Chemical inertness guarantee
-High purity quartz does not react with most chemicals
-Long term use without pollution or precipitation, maintaining the purity of the medium
3. Possess both optical and mechanical properties
-Excellent transparency facilitates process monitoring and observation
-Hardness reaches 7 on the Mohs scale, wear-resistant and scratch resistant, with a long service life
4. Sealing reliability
-Precision grinding technology achieves vacuum sealing between metal/quartz and quartz/quartz
-Can withstand high vacuum environments above 10 ⁻⁶ Pa
