Stainless steel rectangular sight glass is an observation device used in industrial production equipment, mainly used to observe the flow and reaction of liquids, gases, steam and other media, ensuring the normal operation of production. Its material is usually stainless steel, which has the characteristics of corrosion resistance and pressure resistance, and is suitable for industrial fields such as petroleum, chemical, chemical fiber, medicine, and food.
Material and specifications
The shell material of the stainless steel rectangular mirror can be carbon steel or stainless steel, and the window material is usually tempered borosilicate glass, high borosilicate glass, or quartz glass. The sealing material commonly used is nitrile rubber or polytetrafluoroethylene. Its working pressure can reach 0.6MPa, and the working temperature range is 0-200 ℃. Common specifications include various sizes such as 200 * 80, 1000 * 80, etc.
Application scenarios and maintenance
Stainless steel rectangular sight glasses are widely used in equipment such as pressure vessels, vacuum vessels, tanks, reactors, filters, boiling beds, etc., for observing the internal conditions of containers. The window glass is a vulnerable component, so it should be handled with care during installation and attention should be paid to its limitations in temperature and pressure resistance. For example, the temperature resistance range of tempered borosilicate glass is 0-180 ℃, and the temperature resistance range of quartz glass is even higher, reaching 0-1000 ℃. In addition, the square mirror allows for a sudden temperature change of less than 60 ℃ to prevent the glass from breaking due to excessive temperature differences.
