Collection: Tubular Glass

Tubular sight glass is also be named Glass tube, Glass pipe, tubular sight glass, Tubular gauge glass in many country, 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
1)borosilicate glass tube
2)quartz glass tube
Borosilicate glass tube and quartz glass tube can work in the acid and alkali media, at the same time borosilicate glass and quartz glass can bear in high pressure and temperature 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 on the tubular sight glass
The red line on 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.
