Profesional Monel 400 Pipe Manufacturer
Monel 400 (UNS N04400) pipe is a kind of nickel-copper alloy. It is popular for its excellent strength, high corrosion resistance, and outstanding ductility. They can withstand seawater, acids, alkalis, & other corrosive environments.
At Tuolian, we supply monel 400 pipes of different types including seamless, welded, round pipes, square pipes, special pipes, and more. They are available in 5mm to 350mm outer diameter, 0.2 to 8mm thickness, and 1000 to 6000mm length. Full customization is offered to meet your specific requirements.
Our Monel 400 pipes are typically manufactured according to various international standards, including ASTM B165, ASTM B163, ASTM B725, and ASME SB 165. These standards specify the dimensions, tolerances, materials, and testing requirements for this material.
Monel 400 pipes are commonly used in marine engineering, chemical processing, petrochemicals, and oil and gas industries. These pipes are also used in heat exchangers, boiler feedwater heaters, and oil refinery piping systems.
