Monel K-500 Welded Pipe Tube (UNS N05500 / W.Nr. 2.4375)
High-strength corrosion-resistant alloy Pipe Tube for marine components and chemical processing
As a leading Chinese Monel pipe supplier, SEATHER TECHNOLOGY manufactures and supplies a full range of Monel K-500 welded pipe tube with excellent quality and competitive pricing.
MONEL® alloy K-500 (UNS N05500 / W.Nr. 2.4375) is a high-strength, corrosion-resistant nickel-copper alloy that combines the outstanding corrosion resistance of Monel 400 with the added advantages of greater strength and hardness. These enhanced properties are achieved through the addition of aluminum and titanium and subsequent precipitation hardening.
Monel K-500 welded pipe tube is produced by bending and welding high-quality Monel K-500 strip or plate. Because welded tubing performance depends heavily on raw material stability and welding precision, SEATHER selects raw materials exclusively from reputable mills and applies advanced splitting, forming, and welding technologies to ensure consistent tube integrity and weld quality.
For applications requiring enhanced mechanical properties or corrosion resistance, SEATHER also provides solution-annealed Monel K-500 welded pipe & tube using our continuous online solid solution equipment. This process improves material homogeneity and strengthens the weld area, ensuring reliable performance even under demanding service conditions.
With stable quality, precise dimensions and customizable specifications, SEATHER’s Monel K-500 welded pipe & tube is the ideal solution for customers seeking high strength, corrosion-resistant piping for marine engineering, chemical processing, pumps, valves and high-stress environments.
