Flange Type Sight Glass

KINGMAN Sanitary Flange Type Sight Glass adopts flange bolt fastening structure. Stainless steel flange base fitted with round tempered glass disc, designed as observation port for tanks, reactors and pipelines. It can directly observe internal material reaction, liquid level, flow and impurities. Flange connection offers strong pressure resistance. Mirror polished inner surface supports CIP online cleaning, widely used for tanks in pharmaceutical, food and fine chemical industries.

    Features

    • Flange bolt fastening structure with even force distribution and high pressure resistance, ideal for pressure vessels and tanks.
    • Round tempered glass disc delivers wide viewing field and uniform light transmission for clear inspection.
    • Mirror polished stainless steel flange with flat contact surface and stable sealing performance.
    • Easy assembly and disassembly; release bolts to remove glass disc for cleaning or replacement.
    • Smooth dead-zone-free inner cavity minimizes material buildup and supports online cleaning.
    • Resistant to medium corrosion, compatible with various liquid media.

    Working Principle

    Sanitary Flange Type Sight Glass realizes visual monitoring inside tanks or pressure vessels via tempered glass disc fixed by flange. Internal medium and material reaction status can be observed directly through glass. Multiple bolts fasten flange evenly, compress gasket and glass to withstand vessel pressure and avoid medium leakage. CIP cleaning flushes inner glass surface to remove deposits and keep glass transparent for long-term observation.
