Alloys comprising nickel, iron, copper, chromium, silicon, manganese, and nickel are used to create these Duplex 2205/ 31803 Buttweld Fittings. These alloys provide good low-temperature toughness and weldability. Additionally, they offer resistance remarkably to pitting and crevice corrosion, even in oxidizing and acidic conditions. In temperatures around 150 degrees Celsius, the Duplex 2205 Buttweld Pipe Fittings are resistant to chloride stress corrosion cracking. Duplex 2205/ 31803 Buttweld Fittings work well in caustic conditions and offer high weldability since ferrite is present in them.
Benefits abound in the Duplex 2205/ 31803 Buttweld Fittings we produce. Only a few benefits include excellent mechanical strength and good resistance to corrosion stress cracking. The austenitic-ferritic stainless steel used to make our Duplex Steel Fittings can withstand localized corrosion in hostile environments, including pitting, crevice corrosion, and stress corrosion cracking.
Duplex 2205 is a two-phase, ferritic, austenitic stainless steel that contains 5 to 6% Nickel, 3% Molybdenum, and around 22% Cr. The duplex steel buttweld fittings are also available in various shapes, including end pipe caps, stub ends, equal and unequal tees, concentric and eccentric reducers, 45-degree, 90-degree long and short radius elbows, and many more.
Where are Duplex 2205/ 31803 Buttweld Fittings used?
They are widely used in oil and gas pipeline equipment, plumbing, chemical, food processing, manufacturing, pulp and paper, water supply systems, power plants, and various other sectors.
