Hongwo Clear Quartz Tubes: Precision Engineered for Critical Applications

When purity matters, fused silica cylinders from Hongwo deliver 99.991% SiO₂ content with industry-leading consistency. Unlike standard quartz glass that degrades under thermal cycling, our Type I synthetic quartz maintains 92% UV transmission after 5,000 hours at 1200°C.

Material Science Breakthroughs

Hongwo‘s proprietary plasma polishing eliminates surface defects that cause 73% of field failures in competitor tubes. Key differentiators:

OH Content: ≤0.5ppm (vs. industry 2-5ppm)

Thermal Stability: 1730°C softening point

Bubble Formation: 0/cm³ through automated detection

Here’s what most buyers miss – our five-millimeter OD tubes actually outperform 6mm competitors in UV-C applications due to optimized crystal structure.

Manufacturing Innovations

Field data reveals our bubble-free forming process (Patent CN2025HKW028) reduces scrap rates to 0.3% versus the 5-8% industry average. The secret? Real-time X-ray monitoring during draw processes catches inclusions at 3μm resolution.

Applications demanding the clearest quartz tube solutions:

✓ Semiconductor: Wafer boats with ≤0.01μm surface roughness

✓ Photonics: 98.7% transmission from 180nm to 3.5μm

✓ Chemical Processing: Zero corrosion after 1yr in 40% HNO₃

Quality Assurance

Every Hongwo crystalline silica product undergoes:

XRF purity verification (on-site)

Laser scatter testing for micro-cracks

ISO 9001:2025 certified dimensional checks

The kicker? Our 36-month warranty covers thermal shock failures – something no other manufacturer dares to promise.

From laboratory spectrometers to industrial plasma etchers, Hongwo transparent quartz piping sets the global standard for material purity and reliability.
