Flange are piping grades that are used in joining piping equipment of different specifications, allowing them to provide stability to the different applications. Monel 400 Flanges are nickel-copper alloy grade that has enhanced corrosion resistance properties. These flange are used in reducing and mildly oxidizing environments. The Monel Flanges possess superior strength and have outstanding resistance against chloride stress corrosion cracking.
These flange have a density of 8.80 g/cm3 and have a melting point between 1300 to 1350 degrees C. Alloy 400 Flanges have good weldability and are seen in marine oxidizing environments. These flange have enhanced mechanical properties and possess a hardness between 125 to 215 Brinell. They possess a thermal conductivity of 22 W/mK.
Table of Content
The Alloy 400 Blind flange, on the contrary, is designed without any protruding hub. These flange help in cutting the flow of media across different conditions. They are generally bolted in place, allowing room for repair and maintenance. These flange have a recessed socket wherein the pipe grade is attached and welded in place using a single fillet weld. ASTM B564 N04400 Threaded flange has threads that allow it to align to subsequent grades. These flange are commonly preferred in applications where stress on the grade is low.
