Description

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.

​EN 1092-1 & ASME B16.5 / B16.47 Flange Which One to Use?

  • EN 1092-1: Requires standard number, type, DN, PN, material, manufacturer, heat number.
  • ASME B16.5: Requires manufacturer name or trademark, material designation (e.g., A182 F316L), class, NPS, schedule (if applicable), B16.5, and heat number.
Scenario Recommendation
Project in Europe, Asia, or spec calls for PN Use EN 1092-1
Project in North America, or spec calls for Class Use ASME B16.5 / B16.47
Connecting to existing flanges Must match the standard – do not mix EN and ASME directly
International oil & gas (offshore) Often ASME, but some European operators accept EN with PN/Class conversion

* Never directly bolt an EN 1092-1 flange to an ASME B16.5 flange. Bolt circle diameters, hole sizes, and facing dimensions are different. Use a proper adapter flange or a custom-made transition piece designed to both standards.

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.
