Short Description:

can offer as Red Line, Standard, Heavy Wall, High Pressure, Diameters range from 1/2″ OD to 1 1/2″ OD. End finishes may be cut, ground, or fire polished depending on application. Pressure ratings is depending on end finish, diameter, and length required. Heat resistant up to 400 degree centigrade(borosilicate glass) and 1100 degree centigrade(quartz 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 glass1）borosilicate glass tube2）quartz glass tubeBorosilicate 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.Specification• Material: soda-lime glass, borosilicate glass, quartz glass.• Classification: standard, heavy wall.• Wall thickness: 1-30 mm.• Inside diameter: 1-100 mm.• Outside diameter: 2-150 mm.• Length: 30-300 mm.• Max working temperature: 1100 °C.• Max working pressure: 400 bars.Features and Advantages• Corrosion resistanceGlass material have stable chemical property. We have quartz glass and borosilicate glass for aggressive working environment.• High working temperature and pressureOur 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 glassThe red line on the tubular sight glass can make the liquid level more clear for reading.• Precise dimensionWe can customize the tubular gauge glass according to the required dimension. We can achieve ±0.01 mm tolerance for accurate instruments application.• Easy to cleanThe tubular gauge glass can be cleaned easily by water. With suitable cleaning, the tubular gauge glass can be used as long as 10 years.Application1. Household electrical appliance2. Environmental engineering and chemical engineering3. Lighting4.
