Customized Gauge Glass Products with Accurate DimensionYuanBo Engineering Co., Ltd. devotes to produce high quality standard and thick wall gauge glass with polished clear surface and edge for more than 10 years. We have technically advanced machinery, skillful workers as well as professional salesman.Our main product coversall kinds of gauge glass, such as transparent gauge glass, reflex gauge glass, round sight glass and tubular gauge glass. We can customize the dimension and shape of gauge glass according to customers' requirements. We can also produce optical glass, step glass, glass disc, glass tube, laboratory glass, glass rod and glass panel.Product descriptionQuartz glass features: 1. High purity :99.99%-99.999% SiO2. 2. Hardness: Mohs hardness 5.3-6.5.3. High temperature resistance: continuous work below 1200℃, 4. Acid and alkali resistance: except hydrofluoric acid, quartz glass does not react with any acid and alkali. Stability is 30 Twice as much as ceramic and 150 times as much as stainless steel 4. Electrical insulation: 10000 times of ordinary glass. 5. High transmittance: 85-95%, depending on the spectrum. 6. Excellent thermal shock stability: low thermal expansion coefficient, 5.5×10-7/℃.Features and AdvantagesCorrosion 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 in the tubular sight glassThe red line in 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 tubula
