High-Purity Quartz U-Tube — Performance, Advantages and Industrial Value-sara
2026/07/17
Introduction
With the rapid upgrading of laboratory analysis, chemical corrosion reaction, semiconductor gas circulation and high-temperature heating systems, traditional glass and metal pipelines can no longer meet the requirements of high temperature resistance, high purity and anti-corrosion operation. As a core customized quartz glass component, quartz U-tube (U-shaped fused silica tube) has gradually become the preferred pipeline solution for high-end industrial and scientific research equipment due to its stable physical and chemical properties and unique structural design.
Excellent Material and Core Performance
Quartz U-tube is made of 99.99% high-purity fused silica raw material, with ultra-low metal impurity content and low hydroxyl value.
After precision hot bending, high-temperature annealing and flame polishing treatment,
the product eliminates internal stress and achieves extremely stable comprehensive performance.
1. Outstanding high temperature resistance
The continuous working temperature can reach 1100°C, and the instantaneous temperature resistance is up to 1300°C.
With an ultra-low thermal expansion coefficient, the quartz U-tube will not crack or deform under rapid cold and hot alternating conditions,
showing excellent thermal shock resistance.
2. Strong chemical corrosion resistance
The material has extreme chemical inertness.
It can resist most strong acids, organic solvents and corrosive gases under high temperature conditions,
without precipitation of impurities or secondary pollution. It is far more durable than ordinary glass and stainless steel pipes, and only hydrofluoric acid and hot strong alkali will cause slight corrosion.
3. High optical transmittance
The transparent quartz U-tube has a visible light transmittance of more than 93% and excellent UV transmittance,
which is convenient for real-time observation of internal liquid and gas circulation, reaction status and flow changes.
It is very suitable for photocatalysis, spectral analysis and optical monitoring systems.
4. Precise and durable bending structure
The U-shaped integrated bending design avoids pipeline connection dead angles and leakage risks.
The smooth transition of the bending part reduces gas-liquid flow resistance. After strict annealing treatment,
the product has high mechanical stability and long service life in long-term continuous operation.
