We supply high-performance nickel alloy pipes strictly manufactured in accordance with ASTM B444 standard, made from premium UNS N06625 (Alloy 625). The pipes feature a bright surface finish and a thickness range of 0.1-60 mm, suitable for various high-demand industrial applications.
UNS N06625 (Alloy 625) is a high-strength nickel-chromium-molybdenum alloy, renowned for its exceptional corrosion resistance (including resistance to seawater, acids, and chloride-induced stress corrosion cracking), excellent high-temperature strength, and good ductility. The bright surface finish ensures superior smoothness, cleanliness, and aesthetic appearance, while also reducing fluid resistance and facilitating easy cleaning.
The seamless manufacturing process (for applicable thicknesses) ensures uniform wall thickness, high structural integrity, and reliable pressure-bearing capacity. These nickel alloy pipes are widely used in harsh industrial environments such as petrochemical processing, offshore engineering, marine systems, aerospace, and high-corrosion piping projects.
Key Specifications:
Standard: ASTM B444
Material: Nickel Alloy UNS N06625 (Alloy 625)
Surface Finish: Bright Surface
Thickness Range: 0.1 – 60 mm
