Product Description

C&D Hign Quality Borosilicate Glass Tube with 700°C FIRE RESIST  

Product Description

Borosilicate Glass Tube is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glass tubes are known for having very low coefficients of thermal expansion (3.3 × 10−6 K−1 at 20 °C), making them more resistant to thermal shock than any other common glass. Borosilicate glass tube is usually used in tubular level gauge for high temperature and pressure resistance, which is also known as tubular gauge glass, pyrex glass tube.
