One-piece window (flange connection)

Powder device manufacturer delivery
○ Custom-made cases of integrated windows (site glasses) to use and use to flanges.

I would like to install a look in the tank, but because the flood scattering and vapor go up, dirt is noticeable, and I asked for the production of the window from the customer who needed regular maintenance.

When removing, it is likely to cause a drop or crack, etc. of glass.
The flange bolt nut removal is troublesome.
As it is evacuated, withstand voltage is also necessary.

Produced by the specification that can be attached to the flange based on the integrated window [NMB].
The window frame and the glass are fixed and the glass does not drop off.
Convert a flange to a ferrule with a joint, and the window itself is installed in a clamp band, so it is easy to remove.
Design intensity to withstand vacuum draw.
Change the packing to fluorine rubber and improve chemical resistance.
