19mm round sight glass

Circular Sight Glass,Round Sight Glass,Borosilicate Glass,Quartz Glass

Circular sight glass, also named sight glass disc, circular gauge glass, round sight glass, flat plate circular glass discs, etc, commonly it uses the types of materials as below. We suggest different material according to environmental conditions, for instance work temperature, work pressure, acid and alkali of the media.

1）soda-lime glass-max work temperature 280 °C

2）borosilicate glass- max work temperature 450 °C

3）aluminum-silicate glass- max work temperature 650 °C

4）glass-ceramic- max work temperature 750 °C

5）quartz glass- max work temperature 1100 °C

6）sapre glass- max work temperature 2000 °C

7）cobalt blue glass-flame observation

Circular sight glass is commonly used in beer, sugar, chemical, petrol and medicine pipes and flanges for observing the liquid flow and liquid level.

1) For increasing the sight glass strength, the finished glass is often to be tempered and annealed.

2) For increasing the resistance of sight glasses on the aggressiveness of the working environment and in the use of high temperatures and pressures, additional use of mica shield is recommended. If you need the mica shield, grate gasket, asbestos gasket, pls note it.

Features

• Stability

Round sight glass has stable chemical property. It can resist acid and alkali, so that it suits to be applied in industry for long life.

• Temperature

Work temperature:280-2000°C

• Pressure

The highest working pressure that the round sight glass can stand is 500 bars.

• Light transmittance

Our round gauge glass has high light transmittance, which can make sure the liquid level or flow clear.

Precautions

*According to the medium, temperature,pressure,etc.The circular sight glass should be inspected and in routine maintenance periodically

*Very be careful of the disintergrating slag of the broken order to prevent it enter medium,the manufacturer or user should appropriate safety precautions.
