Monel 400 Tube & Pipe is a premium nickel-copper alloy product known for its outstanding resistance to seawater, strong acids, alkalis, and stress corrosion cracking. The alloy, composed primarily of nickel (around 63%) and copper (around 30%), offers excellent mechanical properties and is highly suitable for both high and low temperature applications. Labdhi Metals, a leading manufacturer, stockist, and exporter, supplies Monel 400 tubing and piping solutions that comply with international standards such as ASTM B165 and ASME SB165.
The high corrosion resistance of Monel 400 Tube & Pipe makes it an ideal material for marine applications, chemical processing, hydrocarbon services, and power generation. It performs well in saltwater, hydrofluoric acid, and caustic solutions, offering durability and long service life in harsh environments. Labdhi Metals provides these tubes and pipes in a variety of wall thicknesses, outer diameters, and lengths to meet the specific needs of industries worldwide.
Available in both seamless and welded types, Monel 400 Tube & Pipe is manufactured with tight dimensional tolerances and high surface finish. Labdhi Metals ensures every product undergoes comprehensive quality testing, including hydrostatic testing, PMI, ultrasonic testing, and mechanical property verification. Tubes are delivered in annealed condition to ensure formability and ease of installation.
With excellent weldability, Monel 400 can be joined using standard welding techniques without post-weld heat treatment, which adds to its industrial versatility. Its mechanical strength remains stable in cryogenic and elevated temperature ranges. This makes it suitable for condensers, heat exchangers, boiler feedwater heaters, and instrumentation lines in industries such as petrochemical, shipbuilding, and oil & gas.
