Product Overview

Engineered for marine/chemical high-corrosion scenarios, this Monel 400 (UNS N04400) nickel-copper alloy fin tube meets ASME SB163 standards, featuring helically wound G-type fins cold-formed from the same material for an integral monolithic design. It eliminates galvanic corrosion risks, excelling in seawater, hydrofluoric acid, and high-velocity steam up to 480°C (896°F). With 5x longer lifespan than stainless steel in chloride-rich services, it's the trusted choice for offshore platforms and chemical processing plants.

Chemical & Mechanical Properties
Chemical Composition (Per ASME SB163/ ASTM B163)
Element Content (%) Critical Role
Nickel (Ni) 63.0 min Acid resistance
Copper (Cu) 28.0-34.0 Seawater immunity
Iron (Fe) ≤ 2.5 Purity control
Manganese (Mn) ≤ 2.0 Work hardening
Carbon (C) ≤ 0.3 Weldability
Sulfur (S) ≤ 0.024 Corrosion resistance
Thermal Conductivity 21.8 W/m*K (Monel 400)
Mechanical Properties (Integral Fin Tube System)
Property Value
Tensile Strength ≥ 480 MPa
Yield Strength ≥ 170 MPa
Max Service Temp. 480°C (896°F)
Hardness 65-90 HRB
Fin Bond Integrity Zero detachment at 10,000 cycles
Corrosion Rate in Seawater < 0.025 mm/year
Key Applications & Competitive Advantages
  • Offshore Oil & Gas: Seawater coolers on FPSO vessels & platforms.
  • Chemical Processing: HF alkylation unit heat exchangers.
  • Desalination Plants: Brine heaters in MED/MSF systems.
  • Marine Propulsion: Condensers for naval vessels.
  • Nuclear Power: Auxiliary cooling systems (ASME III certified).
Why This Solution is Unrivaled
20+ Year Lifespan: Verified in North Sea splash zone per NORSOK M-001.
Zero Maintenance: Immune to pitting/crevice corrosion in chlorides.
Thermal Efficiency: 22% higher HTC vs. bimetallic tubes (per TEMA data).
Customization: Fin density (4-12 FPI), tube OD (15.88-50.8mm), and length (≤18m).

It's hot and humid here, and our old wrap-on tubes used to rust like crazy. Switched to your extruded ones—the aluminum fin covers the steel pipe perfectly, so corrosion shouldn't be an issue.

the SS409 pins resist sulfur corrosion better than carbon steel pins we used earlier. In furnace service, that means longer runs between maintenance.

For power plant boilers, especially in industrial settings like ours, these tubes work. Good heat transfer, holding up well.
