Quartz glass features:

1. High purity :99.99%-99.999% SiO2.

2. Hardness: Mohs hardness 5.3-6.5.

3. High temperature resistance: continuous work below 1200℃,

4. Acid and alkali resistance: except hydrofluoric acid, quartz glass does not react with any acid and alkali. Stability is 30 Twice as much as ceramic and 150 times as much as stainless steel

4. Electrical insulation: 10000 times of ordinary glass.

5. High transmittance: 85-95%, depending on the spectrum.

6. Excellent thermal shock stability: low thermal expansion coefficient, 5.5×10-7/℃.

Features and Advantages

Corrosion resistance

Glass material have stable chemical property. We have quartz glass and borosilicate glass for aggressive working environment.

High working temperature and pressure

Our standard size tubular gauge glass is suitable in no pressure and low temperature environment. Our heavy wall kind tubular gauge glass can work safely in high pressure and high temperature environment for a long time.

We can draw a red line in the tubular sight glass

The red line in the tubular sight glass can make the liquid level more clear for reading.

Precise dimension

We can customize the tubular gauge glass according to the required dimension. We can achieve ±0.01 mm tolerance for accurate instruments application.

Easy to clean

The tubular gauge glass can be cleaned easily by water. With suitable cleaning, the tubular gauge glass can be used as long as 10 years.
