Glass ring tubular sight glass type 640 PN 16

Glass ring tubular sight glass type 640 PN 16

Product catalog summary

Overview: The document describes the specifications and usage of glass ring tubular sight glasses, specifically type 640, used for observing filling and flow in pipelines. These sight glasses allow for 360° monitoring of devices and systems.

Specifications: The sight glasses are designed for installation between flanges according to DIN 1092-1 PN 16. They are free of dead space when installed correctly. The materials used include tempered borosilicate glass and acrylic glass, with operating temperatures up to 280°C and 80°C respectively. The maximum pressure is 16 barg, with higher pressures available in type 641.

Installation Notes: Proper seals matching the sealing surfaces should be used, and the screw material should be equal to or higher than the flange material. Lubrication of the screw thread and head is recommended. The installation should prevent pipe forces, vibrations, and pressure shocks from affecting the glass rings.

Special Versions/Options: High-pressure variants (Type 641 PN 25/40) and ASME B16.5 variants (Type 640A) are available. Custom manufacturing and additional options can be requested.

Operating Conditions: The choice of glass and seals affects operating conditions. Borosilicate glass is suitable for temperatures up to 280°C, while acrylic glass is suitable up to 80°C. Various gasket materials are compatible with different temperature ranges.

Product Code Structure: The product code provides information on the type, nominal size, glass type, total length, and variant. For example, the code 11-640-200-2-050-000 indicates a standard version with DN 200, borosilicate glass, and a standard length of 50 mm.

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