Monel 400 and Monel K500 Pipes are high-strength, corrosion-resistant nickel-copper alloy pipes designed for use in highly demanding marine, chemical, and industrial environments. With excellent resistance to seawater, acidic media, and alkaline conditions, Monel alloys are particularly valued for their durability in chloride-rich, saline, and hydrofluoric acid applications.

Monel 400 (UNS N04400) is a solid-solution alloy offering outstanding resistance to corrosion, especially in reducing environments. It maintains its strength and toughness across a wide range of temperatures. Monel K500 (UNS N05500), an age-hardenable version of Monel 400, delivers significantly higher mechanical strength and hardness while retaining excellent corrosion resistance.

We supply both seamless and welded Monel pipes in accordance with ASTM B165, ASTM B725, and ASTM B775 standards. These pipes are available in a wide range of sizes and schedules with end connections including Plain End (PE), Beveled End (BE), and Threaded End (TE). Surface finishes include mill finish, pickled and passivated, or custom polished upon request. click here

At Middle East Piping, our Monel pipes are sourced from top-tier mills such as Special Metals, Sandvik, and other ISO-certified manufacturers. We regularly supply Monel 400 and K500 pipes to projects in Saudi Arabia, UAE, Qatar, Bahrain, and Kuwait, supporting offshore, desalination, petrochemical, and chemical handling systems. click here

Whether for seawater piping, heat exchangers, or chemical reactors, Monel 400 and K500 pipes deliver unmatched performance in environments where both corrosion resistance and high strength are critical.
