Sight glass flange

Overview:

The sight glass flange is a flange pipe fitting used for installing sight glasses. Similar to ordinary flanges, the sight glass flange has two connection surfaces and is connected to the matching flange on the pipeline through bolts. Bolt holes are evenly distributed around it to facilitate the installation of bolts and achieve a tight connection. There is a circular opening at the center of the sight glass flange for installing the sight glass or sight glass assembly.
