Glass ring tubular sight glass type 641 PN 25/40

Product catalog summary

Overview: Glass tube sight glasses are used for observing the filling and flow in pipelines, providing 360° monitoring of systems. Type 641 is designed for mounting between flanges according to DIN 1092-1 PN 25/40, ensuring no dead space when installed correctly.

Specifications: The sight glass can operate at temperatures up to 80°C with acrylic glass and up to 280°C with tempered borosilicate glass. The maximum operating pressure is 40 barg, with specific pressure ratings for different materials and sizes.

Materials: The sight glass is available in tempered borosilicate glass and acrylic glass, with special materials available upon request.

Installation Notes: Proper seals should be used, and the screw material should be equivalent to or higher than the flange material. Lubrication of screw threads and heads is recommended. The installation must prevent pipe forces, vibrations, and pressure surges from affecting the glass rings.

Operating Conditions: The choice of glass and seals affects the operating conditions. Borosilicate glass is suitable for higher temperatures and pressures compared to acrylic glass.

Special Versions/Options: An ASME B16.5 variant (Type 640A) is available, and additional options can be requested.

Product Code Structure: The product code provides information on the type, nominal size, glass type, total length, and variant. For example, the code 11-641-50-2-050-000 indicates a standard version with DN 50, PS max. 40 barg, borosilicate glass, and a standard length of 50 mm.

Optional Accessories: FEP protective screens or coatings are available for high pH values.
