The austenitic and ferritic characters of duplex make it much stronger and corrosion resistant than ordinary steel. There are different types of flanges made out of this material. The UNS S32205 Duplex Stainless Steel Slip On Flanges are used in connections with seamless pipes mostly. Due to the precision in the seamless pipes, they are slipped on through the flanges and therefore allow for better connections at the precise locations. The Werkstoff No 1.4462 Duplex Blind Flanges are used to end the connection in piping permanently. The ending flanges could be of different types as well, but all of them are used to terminate a connection. To increase strength at connections, the Duplex 2205 Weld Neck Flange is used. The weld neck provides additional strength and additional surface for welding. Flanges are sometimes used with filler material for efficiency at welding. Great Steel & Metals also produces socket weld flanges of all grades. The Astm A182 UNS S31803 Socket Weld Flanges are used to make sure that the pipes do not slip or have leaks. The addition of the socket holds the pipes within and therefore allows for much secure connections. We can offer detailed information upon contact.
