    Features of Nickel alloy 20 seamless pipe

    Monel 400 seamless nickel alloy pipe

     

    Nickel-Copper Chemistry:

     

    UNS N04400 (63Ni-34Cu) maintains single-phase structure. Iron controlled <2.5% prevents galvanic corrosion. Manganese (<2.0%) enhances seawater resistance.

     

    Marine Environment Performance:

    Seawater Corrosion: <0.025 mm/year at 2.4 m/s flow

     

    Crevice Corrosion: No attack after 30 days in chlorinated seawater

     

    Biofouling Resistance: 90% reduction vs. titanium

     

    Seaworthiness Testing:

     

    ASTM G52 proof testing in synthetic seawater. Eddy current inspection per ASTM E309. Hydrogen embrittlement validation per ASTM F1624.
