Tubular gauge glass, also called tubular glass, tubular sight glass and tubular boiler glass, can be divided into standard size and heavy wall size according to the wall thickness. The standard size tubular glass is commonly used in low pressure boiler, tanks and some other low pressure instruments. The heavy wall kind is suitable to high pressure environment, such as crude oil and water, gas flowmeter or acid and alkali containers.
The material of tubular sight glass is soda-lime glass, borosilicate glass and quartz glass. Borosilicate glass and quartz glass can resist acid and alkali and work in high pressure and temperature environment. But for soft environment application, soda-lime glass is the most economic choice.
There are seven pieces of standard tubular gauge glass.
Standard size is suitable for soft environment.There are two pieces of heavy wall tubular gauge glass.
Heavy wall tubular glass is suitable to aggressive and high pressure environment.

Features and advantages
Corrosion resistance
Glass material have stable chemical property. We have quartz glass and borosilicate glass for aggressive working environment.
High working temperature and pressure
Our standard size tubular gauge glass is suitable in no pressure and low temperature environment. Our heavy wall kind tubular gauge glass can work safely in high pressure and high temperature environment for a long time.
We can draw a red line in the tubular sight glass
The red line in the tubular sight glass can make the liquid level more clear for reading.
Precise dimension
We can customize the tubular gauge glass according to the required dimension. We can achieve ±0.01 mm tolerance for accurate instruments application.
Easy to clean
The tubular gauge glass can be cleaned easily by water. With suitable cleaning, the tubular gauge glass can be used as long as 10 years.
There are two pieces of heavy wall tubular gauge glass with red lines.
The red line in the tubular glass makes the liquid level more clear for reading.Eight pieces of tubular sight glass with clear surface and well ground edge are on the ground.
We can make sure the polished surface and edge without bubble and crack.
Application
Used in tanks or reservoirs for liquid level reading.
Used in petrol industry.
Used as water or gas flowmeter.
There is a piece of tubular gauge glass which is installed in the boiler.
Tubular gauge glass is commonly used in boiler for liquid level reading.There is a piece of tubular gauge glass installed in a instrument used in pipe.
Tubular glass are used in pipe for the flowing of liquid and gas because it will not cause contamination and is transparent.
Package and delivery
Suitable cartons and pallet is used in package to avoid breaking.
Normally, we can deliver the goods within 20 days.
