High-pressure sight glass type 521 PN 63/400

Product catalog summary

Overview: The document provides technical specifications and installation guidelines for high-pressure sight glasses of type 521, designed for observing levels and flow in pipelines. These sight glasses are crucial for monitoring the performance of individual devices and entire systems and are intended for welding into existing pipelines.

Specifications:

Materials: Body made of 1.4571 stainless steel, borosilicate glass DIN 7080, with optional mica protection discs. Gaskets are made of graphite/stainless steel, and screws are A2-70/A4-70.
Temperature and Pressure: Operates up to 280°C with borosilicate glass and up to 300°C with mica protection. Pressure ranges from 63 barg to 400 barg.
Nominal Sizes: DN 25 to DN 200, with custom sizes available upon request.

Installation Notes: During installation, it is essential to protect the sight glass plates from thermal stress, mechanical damage, and welding spatter. Protective measures such as thermal protection and coverings should be implemented.

Product Code Explanation: The product code provides detailed information about the type, nominal size, pressure rating, body material, glass type, gasket material, and any variants. For example, the code 11-521-5-3-1-1-7-000 corresponds to a standard version with specific features like DN 50 welding ends and borosilicate glass.

Optional Accessories: Accessories include round mica discs for temperatures up to 320°C, grid impact protection windows, metal fused safety sight glass for safety applications, and LED lights for Ex and non-Ex areas. Mica discs are recommended for aggressive media, steam, or pressures above 160 bar.
