Product catalog summary
Usage: Longitudinal sight glass fittings, specifically type 335, are designed for observing and illuminating the interiors of closed containers such as boilers and tanks. These fittings are oval and include a sight glass plate secured between gaskets.
Operating Conditions: The fittings can withstand temperatures up to 280°C, with borosilicate glass similar to DIN 7081. The pressure limit is 3 barg. The base frame materials include 1.4571 and 1.4404 stainless steel, while gaskets are available in various materials such as PTFE, FKM, NBR, and others.
Installation Note: After welding the base frame, check for warping of the sealing surface and rework if necessary. Follow specified tightening torques for bolting. The working pressure must be verified with the pressure device as per AD2000 Leaflet B9.
Structure: The sight glass fitting consists of screws, a cover frame, a glass cushion, the sight glass itself, a gasket, and a base frame.
Product Code: The code provides details on the type, length, base frame material, glass type, gasket material, and variant. For example, the code 11-335-550-2-1-4-000 describes a standard version with specific materials and dimensions.
Operating Conditions: The suitability of glass and seals depends on temperature and pressure conditions. Borosilicate glass is suitable for temperatures up to 280°C, with various gasket materials having different maximum temperature ratings.
Optional Accessories: Accessories include nearly dead space-free designs, stepped glass, and FEP protective screens for high pH values.
