Description
Gauge Glass/Level Sight Glass Used in Industry Pipe
Gauge glass also named sight glass or level gauge glass. According to the application requirement for pressure and temperature, different material is used. Each type max working temperature is shown below.
- Soda-lime glass (window glass) widely used for lower cost, working temperature up to 230 °C.
- Borosilicate glass particularly useful for applications in aggressive environments (acids, alkali, water vapor), working temperature up to 350 °C.
- Aluminosilcate glass have similar properties to borosilicate glass, but with better chemical resistance and higher permissible operating temperature of up to 600 °C.
- Quartz glass has long range light transmittance (from ultraviolet to infrared), and its operating temperature is up to 1100 °C.
Round Sight glass:
-
Description
It is mainly used to observe the level of the boiler or other equipment filled with liquid, also can be used as watching glass window for thermal and chemical reaction.
GG-01: Different dimension round sight glass with clear surface and well grinding edge finish used in flange.
GG-02: Round sight glass with a hole in the center make it convenient to clear the surface of the glass.
We can produce wide range dimension of round sight glass.
-
Dimensions of round sight glass.
Special requirement is available, such as dip hole in center, polishing edge and so on.
