Blind Flange
Stainless steel pipe flanges are components used to connect pipes, valves, pumps, and other equipment in a piping system. They provide a means of joining or connecting two pipes together securely and allow for easy disassembly when needed. Stainless steel is a popular material for pipe flanges due to its excellent corrosion resistance, durability, and high strength.
Stainless steel flanges are typically made from austenitic stainless steel grades such as 304 (UNS S30400) and 316 (UNS S31600). These grades are commonly used due to their corrosion resistance and mechanical properties.

Advantages & Disadvantages: Applications
Since it is bolted, the blind flange provides easy access to the interior of a vessel or pipe, unlike a cap that is welded. From the standpoint of internal pressure and bolt loading, blind flanges, particularly in large sizes, are the most high-stressed of all the standard flange types. However, since the maximum stresses in the blind flange are bending stresses at the flange center (that is robust enough to withstand the stresses), they can be safely permitted to be stressed more than other types of flanges.
