New Eagle Industrial Corporation is a trusted manufacturer and exporter of premium high nickel alloy products, specializing in high-performance tubing and piping solutions. We manufacture Monel 400 Seamless Tubes from premium nickel-copper alloy, offering excellent corrosion resistance and mechanical strength. Produced via cold drawing and bright annealing, they ensure precise dimensions, smooth surfaces, and consistent wall thickness. Compliant with ASTM B165, UNS N04400, WNR 2.4360, and ASME SB163, these tubes are ideal for chemical processing, marine, heat exchangers, and high-temperature industrial applications.These Alloy 400 seamless tubes are produced through precision cold drawing or hot extrusion followed by bright annealing to achieve accurate dimensional tolerances and smooth surface finishes. Cold drawing enhances mechanical strength and surface quality, while bright annealing improves ductility and relieves internal stresses.Each ASTM A165 Alloy 400 tubes undergoes strict inspection, including dimensional checks, hardness testing, and non-destructive testing (NDT) to ensure compliance with international standards and consistent performance under demanding operating conditions.
