Clear Fused Silica Quartz Coiled Tube--Amy
Published On: June 24, 2026
1. Client Background
A manufacturer of laboratory thermal circulation equipment needed high-temperature, corrosion-resistant spiral pipes for heating and cooling fluid delivery. Ordinary glass and PTFE coils failed their process standards, so customized transparent quartz spiral tubes were adopted.
2. Drawbacks of Original Parts
- PTFE tubes deform above 100°C and release impurities to contaminate test liquid.
- Common glass coils crack easily under thermal shock, with low light transmittance blocking real-time flow observation.
- Poor dimensional consistency leads to uneven fluid circulation and unstable test data.
3. Custom Quartz Coiled Tube Solution
- Material: High-purity clear fused silica, resistant to acid/alkali, continuous working temperature up to 1100°C.
- Craft: Integral hot bending forming without splicing, full mirror polishing inside and outside, smooth inner wall to avoid liquid residue.
- Structure: Custom spiral coil diameter, pipe wall thickness and coiling turns to perfectly match the client’s circulation equipment.
4. Application Results
- Zero deformation or cracking under repeated hot-cold liquid cycles, service life over 8 times longer than plastic coils.
- High transparency allows direct visual monitoring of liquid flow without disassembly.
- Smooth inner surface prevents medium accumulation, greatly reducing experimental error caused by contamination.
- Stable thermal conductivity ensures consistent temperature control and improves test repeatability.
5. Conclusion
Transparent quartz spiral tubes solve the high temperature resistance, pollution and observation defects of plastic/ordinary glass coils. It is the optimal consumable for lab thermal circulation, chemical cooling and heating systems.
