Standard DIN 2543 is a specification that takes into account different flanges produced in different alloy grades in varying pressure classes. In this instance, PN16 Flange is indicative of its working pressure in bars. Similar to many of the common flange standards, that are used across several industries globally, the DIN 2543 PN16 Plate Flange Dimension is designed to have a standardized set of dimensions, which in turn permits easy interchangeability as well as functionality.
DIN, which stands for Deutsches Industrie Normen is a German Industrial Standards.
The flanges with the dimensions of the DIN 2543 PN16 Standards are to be used at a maximum temperature of about 120°C with up to a working pressure of 16 bar. At a higher temperature range between 120°C to 300°C, a point to be noted is that the yield point of the Carbon Steel DIN 2543 pn16 flanges Material tends to become lower. PN has been derived from the acronym of the French word Pressure Nominale, which is translated as Nominal Pressure. Pn is the official pressure rating as opposed to the actual pressure capability of the component, which in this case is the Stainless Steel DIN 2543 pn16 flange. Usually, a Din 2543 Pn16 Slip On Flange is used in applications that deal with both low pressure and low temperature.
