duplex stainless steel pipes diameter 200 mm
Compared to 317L stainless steel, duplex steel has excellent resistance to chloride pitting and crevice corrosion. The alloy has excellent corrosion resistance to seawater and most concentrations of sulfuric acid. In addition, it is resistant to sulfide stress corrosion cracking (sour gas environments)
Duplex 2205 seamless tubing provides increased resistance to pitting and crevice corrosion, even when the alloy has been exposed to oxidizing and acidic solutions. This alloy is resistant to corrosion cracking associated with chloride ion stress, even at temperatures up to about 302°F. The presence of ferrite in duplex 2205 welded pipe gives this stainless grade enhanced performance in environments containing corrosive media.
