Al-6xn Flanges have good corrosion resistance to sea water and moderate acids. It is stronger than stainless steel flanges and can handle higher temperatures than the stainless steel flanges. The Al6xn Pipe Flange is made up of a material that has iron, 23% nickel, 20% chromium, 6% molybdenum, manganese, silicon, copper, nitrogen, phosphorus, carbon and sulfur in the composition.
Al-6xn Flange
AL6XN Blind Flange
AL6XN Pipe Flange
There are different types of flanges in this range and the Uns N08904 Blind Flanges are used for closure of a pipeline. The blind flanges are useful in maintenance systems to open and close regularly or to permanently close a connection. There are different dimensions to these flanges based on different standards specifications such as the Asme B16.5 Al6xn Socket Weld Flanges. The flanges range in size from ½ inches to 48 inches and the diameters vary according to the pressure classes. The material has minimum yield strength of 53ksi and minimum tensile strength of 108ksi under room temperatures. The Al6xn Forged Flange is made by forging one piece of the raw material to derive the shape. The forged flanges are stronger and can operate with high stress environments. There are different standards such as the ASTM A 240, ASTM B688, ASTM B691 and so on to govern the different dimensions and aspects of the flanges. The AL6XN Blind Flanges are used in high corrosive, high temperature, high pressure systems to control the flow by blocking the end of a pipeline. The most usage of blind flanges is in the maintenance lines of larger pipelines.
