Optical Transmission at Connection Points
Male/female threaded joints maintain 91% UV transmission at 254nm wavelength through the connection zone, versus 65% for cemented joints. -
Vibration-Resistant Thread Engagement
5-turn thread engagement withstands 2G vibration at 50Hz without loosening, preventing lamp misalignment that causes 30% power loss in standard friction-fit assemblies. -
Field-Replaceable Design
Threaded tubes enable on-site lamp replacement in 3 minutes without specialized tools, reducing service calls by 75% compared to welded quartz assemblies.
TOQUARTZ® çözümü
A UV water treatment equipment manufacturer faced 22% annual warranty claims due to quartz sleeve failures at connection points, where standard push-fit seals degraded under UV exposure. TOQUARTZ® threaded quartz tubes with fluoropolymer-compatible threads reduced connection failures to 2% over 24 months. The threaded design maintained consistent 253.7nm transmission while allowing field technicians to replace components without returning units to the factory, saving $45,000 annually in shipping and labor costs.

-
Zero-Contamination Threading
All-quartz threaded connections eliminate metal ion contamination (<0.1 ppb) at 1200°C, critical for semiconductor and solar cell production processes. -
Dimensional Stability Under Load
Threaded joints maintain ±0.05mm concentricity at 1000°C with 5kg suspended load, preventing process tube sagging that causes 12% yield loss. -
Thermal Expansion Compensation
Thread pitch designed with 0.3mm axial clearance accommodates thermal expansion up to 1250°C without binding or cracking.
TOQUARTZ® çözümü
A Japanese semiconductor equipment manufacturer struggled with alumina ceramic tubes that couldn't achieve thread tolerances below ±0.3mm, causing vacuum leaks in their 1100°C oxidation furnaces. TOQUARTZ® delivered threaded quartz tubes with ±0.1mm thread precision that maintained vacuum levels of 10⁻⁶ Torr throughout 1000-hour production runs. The contamination-free quartz threads eliminated the iron and aluminum traces (previously 15-20 ppb) that were causing 8% wafer rejection rates, recovering $120,000 monthly in improved yields.

Usage Guidelines for Threaded Quartz Tubes
Proper handling, installation, and maintenance of threaded quartz tubes ensure optimal performance and extended service life. These guidelines help prevent damage and maximize the value of your investment.
Kurulum Önerileri
- Use PTFE tape or fluoropolymer-based thread sealant for gas-tight connections
- Tighten by hand only - avoid metal tools that can crack threads
- Use mating components with matching thermal expansion properties
- Allow 0.5-1mm expansion clearance in high-temperature applications
- Verify thread compatibility before installation (metric vs. imperial)
Kullanım Önlemleri
- Wear clean, powder-free gloves to prevent contamination
- Store in clean, padded containers to prevent thread damage
- Avoid thermal shock (>200°C/minute temperature change)
- Clean with electronic-grade solvents or deionized water
- Inspect threads for damage before each use
Thermal Cycling Guidelines
- Allow 2-3 minutes per mm of wall thickness for uniform heating
- Implement controlled heating/cooling ramps (<150°C/minute)
- Pre-heat mating components to reduce thermal stress
- Avoid direct flame or concentrated heat sources
- Use heat-distributing shields for uneven heating applications

SSS
Q: What is a threaded quartz tube used for?
A: Threaded quartz tubes are used in applications requiring secure, leak-tight connections in high-temperature, chemically aggressive, or optically demanding environments. Common applications include laboratory analysis equipment, UV disinfection systems, semiconductor processing equipment, high-temperature furnaces, and specialized optical assemblies.
Q: Can quartz tubes be custom threaded?
A: Yes, TOQUARTZ specializes in custom threading for quartz tubes. We can create standard metric and imperial threads (M8, M10, G1/4, NPT, UNF, etc.) as well as custom thread profiles to your specifications. Our precision machining capabilities achieve thread tolerances of ±0.1mm for secure connections.
Q: What temperature can threaded quartz glass tubes withstand?
A: Our threaded quartz tubes can withstand continuous operating temperatures up to 1250°C and have a softening point of approximately 1730°C. The thermal shock resistance is excellent, though we recommend controlled heating/cooling rates for optimal performance. For applications above 1000°C, we provide specialized guidelines for thread engagement and thermal expansion accommodation.
Q: Are threaded quartz tubes chemically resistant?
A: Yes, our threaded quartz tubes offer exceptional chemical resistance. They are inert to most acids (including hydrofluoric acid at room temperature), bases, and organic solvents. They resist corrosion from halogens, molten salts, and most reactive gases. This makes them ideal for chemical processing, analysis equipment, and harsh environment applications where metal or polymer components would degrade.
Q: What are the standard sizes available for threaded quartz tubes?
A: We offer standard threaded quartz tubes with outer diameters ranging from 6mm to 50mm, with wall thicknesses from 1mm to 4mm. Standard thread sizes include M10, M15, M20, G1/4, G3/8, NPT 1/4, and NPT 3/8. Custom diameters up to 300mm and custom thread specifications are available upon request with typical lead times of 2-4 weeks.
