Manufactured to ASME B16.5 standards from ASTM A105N carbon steel, this flange offers robust mechanical properties and is further enhanced with an internal FBE (Fusion Bonded Epoxy) coating and an Inconel 625 weld overlay on the flange face. This combination provides exceptional protection against harsh chemical environments and high temperatures.
