High Temperature Resistant Clear Fused Silica Quartz Tube Customization Case for Tube Furnace-sara
Published On: June 22, 2026
This project is a mass customization case of high-purity transparent quartz tubes for an overseas industrial equipment manufacturer. The customer required high temperature resistant, high light transmittance and corrosion-resistant quartz glass tubes for tubular furnaces, heating treatment and chemical reaction equipment. The client needed stable dimensional accuracy, low thermal expansion and long service life to support continuous high-temperature industrial production.
Client Pain Points
- Ordinary glass tubes cannot withstand long-term high temperature above 900℃, easily deformed and broken.
- Low-grade quartz tubes contain bubbles and impurities, affecting heating uniformity and equipment stability.
- Poor thermal shock resistance, tubes crack frequently during rapid heating and cooling cycles.
- Unstable tube diameter and wall thickness cause poor assembly accuracy and low production yield.
Our Custom Solution
- High-purity Fused Silica Material: Adopt 99.99% pure quartz raw material, no bubbles, no impurities, high light transmittance and stable chemical performance.
- Strict Size Precision Control: Outer diameter, inner diameter and tube length are precisely customized with tight tolerance to ensure perfect assembly.
- High-temperature Annealing Treatment: Eliminate internal stress, greatly improve thermal shock resistance and prevent cracking during repeated temperature changes.
- Flame Polished Surface: Smooth inner and outer wall, clean and transparent, effectively resisting high-temperature oxidation and chemical corrosion.
- Multiple Custom Styles: Straight quartz tube, thick-wall tube, large-diameter tube, open/closed end tubes are all available.
Project Achievements & Customer Feedback
After sample confirmation and mass delivery, the customized quartz tubes have been running stably in the customer’s high-temperature furnace production line. The products show excellent heat resistance, no deformation, no cracking and no discoloration after long-term continuous operation. The overall service life is greatly improved compared with previous materials. Stable size consistency ensures high assembly accuracy and reduces equipment maintenance frequency. The customer finally achieved higher production stability and lower operating costs.
