Super duplex Pipe fittings are made using austenitic and ferritic steel grades. SD Pipe Fittings are developed for specified usage in Oil & Gas industries. These Pipe Fittings also have superior corrosion resistance.
In comparison to Duplex steels, Super Duplex steels have high amounts of molybdenum and chromium content. The dual-phased structure in Super Duplex Steels gives it prominent strength and corrosion resistance. Super Duplex Pipe fittings come in varieties like Elbows, Tees, Reducers, Pipe Cap, Pipe Bend and Stub End. The resistance to chloride environments is high in Super Duplex Steels is high, making them usable in many such applications. Nickel and Molybdenum is added in small amounts to reduce the making costs of Super Duplex Pipe Fittings, This makes it highly cost effective. Tensile strength and yield strength in Super duplex steel is higher in comparison to only austenitic or ferritic steels. These Pipe Fittings are used for marine applications without causing much damage to the surface. Other applications like subsea coastlines, fire fighting systems, offshore coastlines, and injector and water ballast systems make use of SD pipe fittings.SD pipe fittings are extensively used in Oil& gas plants.
