The number is indicative of the nominal pressure in bars. In the instance of DIN 2501 PN10 Flange, the Pressure Nominale or simply known as PN is 10 bar. Similar to most standards specifications like the ASTM or EN, the DIN standards have a set of parameters to be met by the manufacturer. In addition to the DIN 2501 PN10 Plate Flange Dimensions, these flanges are required to meet the pressure-temperature ratings, materials, marking, testing, tolerances, as well as the different methods that can be used to designate the openings for pipe flanges and flanged fittings.
DIN standards always have the pressure rating mentioned next to it as the PN followed by a number.
Although there are several different types of flanges, most buyers across different industries prefer using a DIN 2501 PN10 Slip On Flange over a weld neck type flange for its low cost. However, one has to note that the cost of the flange would depend on the alloy chosen by the buyer. For instance, a carbon steel slip on flange would cost much lower in comparison to a slip on type Stainless Steel DIN 2501 pn10 flange. The material used to build these flanges would be an alloy which has the ability to meet the demands of the application. Which is why alloys such as Monel, Nickel, Inconel, Incoloy, Hastalloy, Titanium, Stainless Steel, Carbon Steel, Duplex Steel as well as Alloy Steel are used as Din 2501 Flange Material during production. Flat Flange Dins 2501 pn10 is well suited to be used for applications involving low and pressure and temperature environments.
