We can produce and deliver nearly any duplex material requirement in lined pipe. while Duplex 2205 is the most common duplex lined material product we supply, we can also deliver Duplex 2304 and Duplex 2207 with reduced lead times as these alloys are stocked. Alloy 2205 (UNS S32305/S31803) is a 22% chromium, 3% molybdenum, 5-6% nickel, nitrogen alloyed duplex stainless steel lined pipe with high general, localized, and stress corrosion resistance properties in addition to high strength and excellent impact toughness.
Alloy Provides pitting and crevice corrosion resistance superior to or Austenitic stainless steel tube in almost all corrosive media. It also has high corrosion and erosion fatigue properties as well as lower thermal expansion and higher thermal conductivity than austenitic.

Technical details at a glance:
