Product Description

Product Description

     The typical pressure bearing industrial sight glass looks like a port window on a ship, and is installed directly onto the sidewalls of tanks and vessels to allow its interior and contents to be visually inspected. Obviously, an opening must be present on the pressure bearing shell of the tank, pipe, or vessel that will host the window. Most common of such openings are industry standard flanges - ANSI size flanges, for example - and reinforcing pads that have been welded onto the opening to compensate for the loss of structural strength caused by the opening; this reinforcement essentially decouples the attached sight glass from flexing with the pressure shell. Highest pressure sight glasses are almost universally circular.

        Sidewall sealed sight windows reduce or avoid the problem of crushing the glass with excessive bolt thrust by using plastic packing material along the sidewalls of the glass lens. Seal is achieved by compressing the packing along the side walls without directly applying bolt thrust onto the glass surface. This layout is slightly more complex than the more common face sealing, but is more forgiving of excessive sealing stresses.
