Weld-on sight glass fittings for the observation of the internals of pressure vessels, silos, gear-trains, separators, pipelines, etc. These sight glass units can be combined with light fittings for use in explosion hazardous areas and safe areas. The cover flanges can be drilled and tapped to take these light fittings.
Sight glass fittings to DIN 28120 are circular flanged sets suitable for welding into or onto vessel walls, complete with relevant matching seals and sight glass disc set between the flange rings.
Based upon these standard thicknesses, distortion free location of the sight glass is guaranteed provided of course that the welding flange has been correctly welded into or onto the vessel wall.
They can be combined with Lumiglas light fittings for use in explosion hazardous areas and safe areas.
