What Is BS 4504?


BS 4504 are classified according to a British system which is now obsolete and is replaced with a much recent EN1092-1 classification system. bs 4504 pn16 Flanges adhere to the pressure class PN16 which is a high pressure containment classification whereas the EN BS 4504 Flange is a low pressure class denomination. BS 4504 Pipe Flanges can come in different types and shapes. BS 4504 pn 10 Flanges can also come in different models and compositions such as the DIN BS 4504 forged flange. The BS 4504 pn 16 Plate Flanges is used in requirements where an end plate is needed in a pipeline application.

Depending on the need for strength, the material could differ such as the Duplex Steel BS 4504 Flanges or the Inconel BS 4504 Flanges. These differences are responsible for the cost differences. Pressure classes such as the DIN86029 PN10 BS 4504 Flanges also determine the price of BS 4504 Flange as well. Apart from the pressure classes, the flanges sometimes will have to deal with specific substances. For instance, the Copper Nickel BS 4504 Flanges are very much resistant to sulfuric acid corrosion. Alloy 20 BS 4504 Flanges is an austenitic alloy that is also very much resistant to sulfuric acid corrosion.

Alloy Steel BS 4504 pn 6 flange belong to PN6 pressure class and is made up of alloy steel. There are Carbon Steel BS 4504 Flange versions as well. The Nickel Alloy BS 4504 pn 10 flange is made up of nickel alloy which is more corrosion resistant than carbon steel. BS 4504 Flange Dimensions vary according to the standard and required application. If the pressure is high and a series A flange is considered, the wall thicknesses are usually higher. Hastelloy BS 4504 pn16 flange is a higher pressure containment class and therefore the wall thickness would be higher.
