    Glass in a sightglass has wear!

    Many know that a sightglass wear, but how much and when the glass should be replaced is less known?

    Here is the answer to this question:

    Wenn we take the most applied hardened borosilicate glass. In the graph you see how many millimeters per month this glass erods at a certain temperature and pH. For example, a sightglass with borosilicate glass in an application where the medium is 170 °C and with a pH of 10, the glass rubs 0.2 mm per month. This does not seem to be much, but that is about 2.4 mm in a year. At 200 °C., this is 8.4 mm. And that is very much !!!

    In general it can be said that the glass of a sightglas erods faster at a pH higher than 7 (lye). Glass is well resistant to acids but less to alkalis.

    Roughly speaking, we advise, in consultation with the manufacturer of the sightglasses, replace the sightglass that is used under extreme conditions every 6 months. In normal conditions, we recommend replacing the sightglass every two years.

    Sightglass Mica disks

    Protection against corrosion and heat
    To minimize the influence of corrosive media or high temperatures on the glass disk, all sightglass with a smooth surface can be equipped with a mica disk.
    This almost completely eliminates glass surface erosion.
