ASME B16.5 Alloy Steel Flange the forged flanges
The alloy steel of ASTM A182 F11 flanges is called chrome-moly flanges. These are flanges that contain chromium and molybdenum, these are the ingredients that make them resistant to corrosion, which also adds to its toughness.
Flanges are butt welded directly to the slope and provide a natural connection. SA-182-F11 LWNRF flanges have longer protruding hubs than standard butt weld flanges. ASTM A182 Low Alloy Steel Forgings cover a wide range of pipe flanges, forged fittings, valves and parts used in boilers, pressure vessels, steam lines and other high temperature applications. This allows flanges to work well in high pressure and high temperature settings. The SA 182 Gr F11 flange is a standard welded pipe flange used to increase pipe lengths in flanged connections.
