    Borosilicate Glass for circular sight glasses or tubular sight glasses
    Borosilicate glass is a kind of glass with silica and boron trioxide as the main glass-forming element. Borosilicate glasses become famous for having very low coefficients of thermal expansion, making them more resistant to thermal shock than soda-lime glass. borosilicate glass is fit to be used in sight glass lens,
    Borosilicate glass is ultra and clear glass with good thermal and chemical properties and outstanding transparent

    Application
    Circular sight glass lens
    Tubular borosilicate glass
    Appliance glass such as furnace, microwave, gas stove etc.
    Industry Glass such as sight glass, linings, etc.
    Lighting equipment (protective glass for high-power spotlights and other lamps)
    Photovoltaic module
    Optical filters
    Primary material for fully tempered glass
    Main properties
    High temperature stability
    Good surface quality
    Outstanding transparency in the visible, UV and IR ranges
    Can be tempered
    High chemical resistance
    Environmental engineering and chemical engineering (lining layer of repellence, autoclave of chemical reaction and safety spectacles);
    Our circular sight glass is required in all areas where the visual inspection of processes in vessels has to be ensured under pressure, at high temperatures or on exposure to chemicals. These sight glasses is made mainly from borosilicate glass, we also produce sight glass lens with alumino-silicate glass or quartz glass or sapphire glass

    *Aluminosilicate glass

    Aluminosilicate glass for boiler gauge glass
    Alumino-silicate glass is mainly composed of Si-Ca-Al-Mg and other alkali metal oxides through a scientific ratio combination, 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, is a variety of high pressure glass window excellent material.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.

    *Quartz glass

    Quartz glass for round sight gauge glass or tubular sight gauge glass
    Normally,quartz glass is fused quartz is the widely usage in industry and home appliances.it is a glass consistant of almost pure silica in amorphous form,it’s purity up to 99.9% according to requirement.
    Advantages
    Softening point is 1730℃,long time work temperature 1100℃,short time work temperature 1400℃
    Shock thermal:taking out the glass from 1100℃ furnace into 20℃ water,no breakage three times.
    The visible light transmittance is more than 93%.
    Corrosion resistant:quartz glass can work in the intense acid and alkaline environment
    Synthetic Quartz Silica and Infrared Optical Quartz both used as the optical glass.
