2205 Seamless Duplex Phase Stainless Cold Rolled Tube For Heat Exchanger


2205 Seamless Duplex Phase Stainless Cold Rolled Tube For Heat Exchanger


Seamless stainless steel pipes, as the name suggests, are steel pipes that are formed in one piece without any weld seams. They are made from solid round stainless steel billets through a series of processes such as piercing, hot rolling, and cold rolling/cold drawing to produce hollow long steel bars. Due to their "seamless" feature, they usually outperform welded stainless steel pipes in terms of pressure-bearing capacity, uniformity, and corrosion resistance.


CategoryDescription
Product NameDuplex 2205 Stainless Steel Pipes / Tubes (Seamless & Welded)
Key Standard GradesUNS S32205 / S31803, ASTM A790/A789, EN 1.4462
Primary FeaturesHigh Strength: Yield strength is over twice that of conventional 316L.
Excellent Corrosion Resistance: Outstanding resistance to stress corrosion cracking (SCC), pitting, and crevice corrosion.
Cost-Effective: Life-cycle cost advantage due to longer service life and potential for weight reduction.
Chemical Composition (%)Carbon (C) ≤ 0.030, Silicon (Si) ≤ 1.00, Manganese (Mn) ≤ 2.00, Phosphorus (P) ≤ 0.030, Sulfur (S) ≤ 0.020, Chromium (Cr): 22.0 - 23.0, Nickel (Ni): 4.5 - 6.5, Molybdenum (Mo): 3.0 - 3.5, Nitrogen (N): 0.14 - 0.20
Typical Mechanical PropertiesYield Strength (σ 0.2): ≥ 450 MPa (65 ksi)
Tensile Strength (σ b): ≥ 620 MPa (90 ksi)
Elongation: ≥ 25%
Hardness: ≤ 32 HRC
Corrosion Resistance DataPREN (Pitting Resistance Equivalent): 33-36
Excellent resistance to chlorides, sulfuric acid, phosphoric acid, and organic acids.
• Superior resistance to Stress Corrosion Cracking (SCC) in chloride-bearing environments.
Available TypesSeamless Pipes (ASTM A790)
Welded Pipes (ASTM A790)
Standard SpecificationsSeamless: ASTM A790, ASME SA790, ASTM A999
Welded: ASTM A790, ASME SA790, ASTM A1010

Welded: Outer Diameter (OD): 1/8" to 48" (or larger), Wall Thickness (WT): Customized as per requirement.
Surface FinishAnnealed & Pickled: Standard dull gray matte finish.
Mechanically Polished: To specific Ra values (e.g., 0.8μm, 0.5μm for sanitary applications).
Electropolished: For ultra-hygienic and superior corrosion resistance (Common for Semiconductor/Bio-Pharm).
Main Application FieldsOil & Gas: Flow lines, pipelines, pressure vessels, offshore platforms.
Chemical & Petrochemical: Heat exchangers, tanks, process piping handling corrosive media.
Pulp & Paper Industry: Digesters, bleach plants.
Environmental & FGD Systems: Scrubbers, seawater cooling systems.
High-Purity Industries: Food & Beverage, Pharmaceutical, and Bio-tech process lines.
Advantages over 316LDouble the Yield Strength allows for thinner walls and weight savings.
Far superior resistance to pitting, crevice corrosion, and Stress Corrosion Cracking.
• Better value in aggressive environments.
