PN6

PN6

A PN6 flange has a fixed nominal pressure rating of 6 bar (approximately 87 psi).

Unlike the ASME/ASA system, the PN system uses a single pressure class designation that assumes the maximum pressure is at ambient temperature (around 20°C).
The maximum working pressure for a PN6 flange generally decreases if the temperature rises significantly.
 
Maximum Working Pressure for PN6 Flanges
 
Temperature RangePN6 Max Pressure (bar)
Up to 20°C (Ambient) 6 bar
Above 20°C (e.g., 100°C) Pressure derates based on material

For common materials:
  • Steel (Carbon or Stainless): The 6 bar rating is typically maintained across a wide temperature range if the material allows for it.
