Bolt-On Sight Windows

Sight windows for ready installation onto existing ASME or DIN standard flanges. These bolt-on sight windows comprise a base with a raised or flat face flange to fit standard ASME or DIN flanges. The glass disc, either borosilicate, quartz or sapphire, is clamped in place by a gasketed glass retainer held by threaded bolts.

Bolt-on sight windows fitting the standard ASME B16.5 Class 150 geometry. These have an RF (Raised Face) type flange. The base flange mounts to the mating flange using traditional installation methods using mounting bolts. The base flange is sealed to the customer vessel with a gasket. A glass window is then inserted into the base flange sealing with a seal gasket. The glass window is sandwiched between the sealing gasket and a cushion gasket protecting the window from vibration. A flange retainer completes the assembly landing onto the cushion gasket.
