Product catalog summary

Overview: The document provides technical specifications and installation guidelines for manhole sight glass fittings, which are used for observation and illumination inside closed containers such as boilers and tanks. These fittings can also function as a blind flange to close entry openings while allowing visual observation.

Specifications: The sight glass fittings are designed to withstand temperatures up to 400°C and pressures up to 16 barg. They are suitable for both liquid and gaseous media. The nominal sizes range from DN 300 to DN 800, with custom designs available upon request. The base flange materials include stainless steel grades 1.4571, 1.4404, 1.4541, 1.4539, and 1.4306. The glass options are soda-lime glass (DIN 8902) and borosilicate glass (DIN 7080).

Installation Notes: Proper seals should be used for the sealing surfaces, and screw materials should match or exceed the quality of the sight glass flanges. Lubrication is recommended for both the screw thread and head.

Operating Conditions: The operating conditions depend on the choice of glass and gaskets. The document provides a detailed table of temperature and pressure compatibility for various gasket materials, including PTFE, FKM, NBR, C4400, Silicone, EPDM, and Graphite.

Product Code Structure: The product code is explained with an example, detailing the composition based on group type, nominal size, base flange material, glass type, gasket material, and variant.

Optional Accessories: Accessories include double glazing, mica discs, sight glass wipers, O-ring gaskets, impact protection windows, LED lights, FEP protective screens, and spraying devices. These accessories enhance the functionality and durability of the sight glass fittings.

Conclusion: The document provides comprehensive information on the design, materials, and installation of manhole sight glass fittings, ensuring safe and effective use in industrial applications.
