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.
