What is DN in flange size?
Diameter Nominal
DN = Diameter Nominal The term Diameter Nominal refers to the internal diameter of a pipe. Together with the nominal pressure rating and the materials class, all dimensions of a piping line, e. g. flange dimensions, are defined by indicating the nominal diameter.
What is a DN flange?
The word nominal diameter refers to a pipe’s internal diameter. For reference, a DN 50 pipe indicates a pipe with an external diameter of 60.3 mm and a wall thickness of 3.65 mm according to EN 10255 (resulting indoor diameter of 53 mm).
What do DN and PN mean on flanges?
Nominal diameter (DN) and nominal pressure (PN) A pipe’s nominal pressure describes the maximum internal pressure that the pipe and its joints are capable of withstanding and it is expressed in bars. A pipe’s nominal pressure describes the working pressure in bars, only for the involvement of water at maximum 20°C.
What does PN mean in flanges?
Pressure Nominale
‘PN’ stands for Pressure Nominale and prefixes the pressure rating, e.g. a PN16 flange is designed to operate up to 16 bar. Typical ratings include PN6, PN10, PN16, PN25, PN40, PN64, PN100. The American ANSI standard refers instead to a pressure / temperature rating termed ‘Class’.

What is DN standard?
It is common to identify pipes by inches using NPS or “Nominal Pipe Size“. The metric equivalent is called DN or “diametre nominel“. The metric designations conform to International Standards Organization (ISO) usage and apply to all plumbing, natural gas, heating oil, and miscellaneous piping used in buildings.
What DN means?
DN also means “Don’t Know.” DN. Definition: Don’t Know.
What is the difference between PN16 and class 150 flange?
Steel pipe flanges are classified as per ASME B16. 5 standard. The term “lb”, “class” and “#” are used interchangeably to designate the pressure rating of the flange. The fact is that 150 lb has no relation to 150 psi and so does the 300 or 600 lb does not correlate to 300 or 600 psi pressure rating.
Is standard for flange?
ANSI B16. 5 -1996 is the official standard for ANSI Class Pipe Flanges and Flanged Fittings, applied specifically to those made from cast or forged materials, as well as blind flanges and some reducing flanges crafted in cast, forged, or plate.
