Duplex 2205 Flanges manufacturer in India offers ASTM A182 F51 UNS S31803 Blind Flange and UNS S32205 Slip On Flange in various pressure class at factory price in Mumbai


Duplex Flanges

Flanges made up of stainless steel are commonly available in the market. One such variety of stainless steel is the Duplex 2205 Flanges that contain the microstructure of both austenitic and ferritic. According to the Duplex Flanges Manufacturer In India, they resist localized corrosion such as pitting and corrosion and also offer good impact strength and toughness. ASTM A182 DSS Blind Flange is used to terminate the pipe and is not advised to be used in temperature settings above 572 degrees F. These Duplex 2205 Weld Neck Flanges offer superior resistance when compared to other stainless steel grades. 

Duplex Stainless Steel Flanges display resistance to localized corrosion due to the presence of chromium, molybdenum, and nitrogen. Hence even after being exposed to acids and oxidation solutions ASME SA182 DSS Plate Flange does not corrode easily. 2205 Duplex Steel Slip On Flanges are used in various connections in a piping system such as oil and gas piping, heat exchangers, and food processing. UNS S31803 Socket Weld Flanges are also used in high pressure storage tanks and shipping boxes. They also resist chloride ion stress corrosion and are used in various seawater and marine equipment. 

Duplex Steel S32205 Lap Joint Flange also resists corrosion in sulfide and chloride environments. They can also resist intergranular corrosion and offer good ductility in low temperatures. Alloy 2205 Pipe Flanges are used in aircraft exhausts, offshore oil drilling, spiral weld tubes for burners fuel and pipes, and power generation industries.  SAF 2205 Raised Face Flange is therefore used in numerous industries. We ensure that they maintain the desired property by passing them through various tests. These tests ensure that Duplex Steel S31803 And S32205 Flanges have been manufactured as per international standards and have inherited the desired properties
