Compare 2205 duplex stainless steel flanges class vs PN ratings
  • Class ratings for 2205 duplex stainless steel flanges are primarily used in the United States, whereas PN rating is preferred by Europe and other regions.
  • They offer similar pressure-temperature ratings but have different units. Class is expressed in PSI whereas PN rating has bar.
  • Their dimensions are bolt hole patterns are different due to their given standards.
Is it possible to get SAF 2205 flanges impact or hardness testing?

Yes, it is possible to get hardness and impact testings on SAF 2205 weld neck flanges. These tests can be useful for assessing flange quality and mechanical properties, especially in high temperatures and pressures.

  • Impact testings will include charpy test which detects the UNS S32205 lap joint flange material’s resistance to sudden impact. There is also an izod impact test, which measures the required energy for fracturing a notched specimen.
  • For testing the hardness of UNS S31803 reducing flange, the most popular methods are Rockwell and Brinell hardness tests.
What materials are frequently used to seal the surfaces of alloy 2205 flanges?

A compatible material should be used for the gasket with alloy 2205 blind flange or it may encounter galvanic corrosion. Common gasket materials are:

  • Graphite which is suitable for elevated temperatures (up to 1000 °C) and corrosive applications.
  • PTFE shows good chemical resistance and low friction properties.
  • Rubber offers flexibility and is resistant to wear.
