Overview: what is a PN16 flange?
A PN16 flange is a PN-rated flange commonly used in European-style piping systems. PN16 indicates a nominal pressure rating system, but actual suitability depends on material, temperature, standard, flange type, facing, gasket, and project design.
Buyers often search “PN16 flange” when they need dimensions, product options, and quick quotation support.
Which standard is commonly associated with PN16 flanges?
PN16 flanges are often specified under EN 1092-1 for steel flanges in European projects. Some buyers may still refer to DIN flange terminology. The supplier should confirm the exact standard, type, facing, and dimensions before quotation.
What flange types can be PN16?
PN16 may appear in different flange types, such as:
- welding neck flange
- plate flange
- slip-on type flange depending on standard
- blind flange
- loose flange systems
- threaded or special types where applicable
Terminology varies by standard system, so drawings are helpful.
Common materials
- carbon steel
- stainless steel
- low-temperature steel
- project-specific material grades
The material grade must be confirmed separately from the PN rating.
PN16 vs Class 150
PN16 and Class 150 are not automatically interchangeable. They use different standards and may have different:
- dimensions
- bolt hole patterns
- pressure-temperature ratings
- facing designs
- marking requirements
A buyer should not replace one system with the other without engineering approval.
