DIN Flanges Dimensions

DIN or as known in its elaborated form  Deutsches Institut für Normung. DIN is a non profit institute that develops norms and standards as a service to several industries, to the state as well as to society as a whole. The DIN Flanges Dimensions are specified and are predominantly used in European countries. The standards developed by DIN lays down both general or detailed specifications for products such as flanges, in addition to procedures and services. PN is often accompanied by the term DIN, which is an acronym for Pressure Nominale.

The PN is used as a prefix to suggest the pressure rating of the Flanges. For instance, the DIN PN6 Flanges is designed to operate at up to 6 levels. While different grades may be used in the manufacture of DIN Standard Flanges, the most common materials include carbon steel, alloy steel and several different grades of stainless steel alloys. In comparison to most stainless steel grades, the Carbon Steel DIN Flange tends to cost lesser due to its low alloying cost. On the other hand, although the cost of Stainless Steel DIN PN40 Flanges is much higher, the alloys offer better corrosion resistance and mechanical properties while having excellent performance across a wide area.
