Container sight glasses with virtually no dead space for maximum process visibility
A current project based on the Type 335 longitudinal tank sight glass demonstrates how a geometrically optimized design can achieve an installation with virtually no dead space.
We tailor standard products specifically to meet customer-specific requirements. The Type 335 is a longitudinal vessel sight glass that is welded into or onto vessel walls. With a viewing width of 50 mm, it enables reliable visual monitoring of the process.
For this project, the vessel sight glass was custom-designed to match the geometry of a pressure vessel. To achieve a virtually dead-space-free installation, the sight glass was precisely adapted to the internal radius of the pressure vessel, creating a smooth transition inside the vessel.
Thermally tempered borosilicate glass based on DIN 7081 is used with a stepped glass geometry, and stainless steel 1.4404 is used for the metallic components. KlingerSil® C4500 is used as the gasket material for pressure-resistant, dimensionally stable sealing.
