What are the differences between an RF and RTJ face type in a flange super duplex?

  • The raised Face flange super duplex is where the gasket seating surface is slightly raised above the main surface. The Ring Type Joint has a groove or ring machined into the flange face, where a metallic gasket is placed.
  • RF flanges typically use soft gaskets whereas RTJ flanges use metal ring gaskets.
  • RF face flanges are commonly used in low to medium pressure applications. RTJ face flanges are preferred for high pressure and temperature applications

How do you choose the right pressure class for a Werkstoff 1.4410 socket weld flange?

  • Determine the maximum operating pressure of the piping system.
  • Consider the temperature at which the Werkstoff 1.4410 socket weld flange will operate.
  • Refer to ASME B16.5 standards for pressure-temperature ratings.
  • Select a pressure class that has a rating above the maximum operating pressure.
  • Evaluate the specific application and the criticality of the process to choose an appropriate pressure class.

Top 3 advantages of super duplex steel flanges

  • Super duplex steel flanges offer excellent corrosion resistance and can be used in offshore oil & gas platforms, chemical processing plants and seawater applications.
  • The flanges exhibit high mechanical strength and toughness.
  • ASTM A182 Gr F53 lap joint flange offers superior performance and longer service life which makes it cost effective.
