Seamac Piping Solutions Inc. is a leading manufacturer and supplier of Duplex Steel Flanges. We are using different metals and alloys to fabricate Flanges. In Duplex Steel, we are using UNS 31803 and UNS 32205 alloys. Duplex 31803 is the most commonly used duplex grade which contains 4% of molybdenum, 25% of chromium, and 7% of a nickel alloy. It has high mechanical strength and provides excellent resistance to stress corrosion cracking, chloride pitting corrosion attack, and crevice corrosion. Duplex 32205 contains chromium of 22%, molybdenum of 3%, and nickel 5-6%. It is two phases of corroded metal which is suitable in an application that needs excellent corrosion resistance and strength.
Duplex 32205 and 31803 are Ferritic-Austenitic Steel grades which are suitable in numerous applications and operations where superior resistance to corrosion requires. We are offering the highest quality Duplex S31803/S32205 Flanges in the global market. We are producing these Flanges in multiple specializations such as class, size range, standard, surface finish, length, wall thickness, and surface finishing. We are also providing custom made Flanges, as per the requirements given by clients.
