What Is PN Flange Standard?


PN in the term PN Flange Dimensions stands for Pressure Nominale. PN is a prefix for pressure rating. For instance, a Flat Flange Pn 16 is designed to operate in pressures up to 16 bar. Typically ratings include the following PN Flange Dimensions i.e. - PN6, PN10, PN16, PN25, PN40, PN64 as well as PN100. The American ANSI standard generally refers to the PN instead to a pressure / temperature rating, which in turn has been termed as Class.

what is the meaning of pn 16

What Is The Meaning Of PN 16?

Although PN 16 is the rating designator for the pn flange standard, which follows a designated number representing the approximate pressure rating in terms of bars; One must note that PN ratings, for e.g. PN16 Slip On Flange does not provide a proportional relationship between varied PN numbers, however, in a manner class numbers do. Commonly, the type of material used in the manufacturing process of the flange pn16 uni 2278 will govern the mechanical properties of the flange. For instance, a Carbon Steel PN16 Flange will be used in those applications where corrosion resistance is not really required though the application has low temperature exposure requirements.

Similar to carbon based steel grades, the properties of Stainless Steel PN16 Flange will be defined by the alloy grade chosen by the client. For instance if he wants a cost efficient alternative then austenitic grade stainless steel 304 is considered to be an apt choice. However, if the client requires the stainless Alloy Steel Pn16 Blind Flanges to have good mechanical properties along with higher resistance to corrosion in comparison to stainless steel grade 304, then we can manufacture the Pn16 Weld Neck Flanges in alloy grade 316. We are one of the largest manufacturers and suppliers of the MS Flanges Pn 16. Click here to learn more about the pn 160 flange table.
