EN1092-1 Type 01A Plate Flange A182 F316L Stainless Steel Flange Flat Face Flanges

EN1092-1 Type 01A Flat Faced Plate Flange F316L Stainless Steel Flange

An EN 1092-1 Type 01A Flat Face Plate Flange made of ASTM A182 F316L stainless steel is a flat, circular steel disc with bolt holes but no hub or raised face. It is designed to be welded directly to a pipe or fitting and uses a full-face gasket (flat sealing surface). The material F316L is a low-carbon, molybdenum-bearing austenitic stainless steel that provides excellent corrosion resistance, especially against chlorides and acids, and resists sensitization after welding.

Application

• Low-pressure piping systems (water, chemicals, oil, gas) where flat face is required (e.g., connecting to plastic, FRP, or cast iron flanges).
• Marine and offshore environments – F316L resists pitting and crevice corrosion from seawater.
• Pharmaceutical and food processing – easy to clean, no crevices (when full-face gasket used).
• Heat exchanger and vessel nozzles with flat face gaskets.
• Wastewater treatment – resistance to chlorides and mild acids.
