How to choose the right sight glass

For different working conditions, the materials and types of sight glasses that should be selected in the industry are also different. Therefore, in the process of choosing a sight glass, you need to first consider your working environment and consider whether these environmental conditions restrict each other. Specifically, you can refer to the following conditions:

1.Operating temperature:

For glass sight glasses, if the maximum rated temperature of the glass is exceeded, the sight glass will lose strength. The effect of pressure should also be considered when considering operating temperature, as increases in pressure and temperature usually occur at the same time.

2.Working pressure:

If the working pressure is too high, thicker glass should be selected, but it is necessary to know the peak temperature to ensure the safety of work.

3.Corrosiveness of the working liquid:

You need to know whether the working liquid is corrosive, which materials are mainly corrosive, whether the liquid has chemical activity under the working temperature and pressure environment, etc., so as to avoid the selected sight glass that cannot be used normally .

4.Whether the work environment is impact-resistant:

Sight glass is generally able to withstand high impact forces, but if your work environment has a high impact force, you need to consider more impact-resistant sight glasses.

5.Whether the working environment is sealed:

Whether the working environment is sealed is an important parameter, which affects whether it is necessary to leave a margin for thermal expansion when installing the sight glass.
