Product Description
Rectangular sight glass, also called Rectangular gauge glass and sight glass , commonly uses the material of soda-lime glass, borosilicate glass, aluminosilicate glass and quartz glass. We suggest different material according to environmental conditions, such as temperature, pressure, acid and alkali.
Soda-lime glass working temperature is up to 230 °C, but it is the most inexpensive material. Borosilicate glass is particularly used in aggressive environment, such as acid and alkali. The working temperature is up to 430 °C. Aluminosilicate glass can resist acid and alkali better than borosilicate glass and the working temperature can reach 650 °C. Quartz glass is the best material, whose working temperature can reach 1100 °C.
Rectangular gauge glass is commonly used in industry, chemical, petrol and medicine pipes and flanges for observing the liquid flow and liquid level.
