High pressure level gauge glass is used in the boiler high pressure steam package of high pressure glass window, is the most important parts of high pressure level gauge. The highest temperature of 500℃, pressure 16-32mpa.
The high pressure level gauge glass is mainly composed of Si-Ca-Al-Mg and other alkali metal oxides through the combination of scientific ratio, in which the content of K2O+Na2O ≤0.3%, belongs to the non-alkali aluminum silicate glass system, after high temperature tempering treatment with high temperature resistance, high pressure resistance, acid and alkali resistance and other excellent physical and chemical properties. It is an excellent material for all kinds of high pressure glass Windows. It is mainly used in power plant, petrochemical, nuclear power plant, deep-sea exploration equipment and other kinds of high temperature and high pressure steam package on the high pressure water level gauge glass window.
