Product Description
ASTM B444 UNS N06625 Nickel Alloy Pipe Bright Surface 0.1-60mm Thickness
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
- Type: Nickel Alloy Pipe (Seamless, as applicable)
- Advantages: High Corrosion Resistance, High-Temp Resistant, High Strength, Bright Surface, Smooth Fluid Flow
- Application: Petrochemical, Offshore, Marine, Aerospace, High-Corrosion Industrial Piping Systems
All pipes undergo rigorous quality inspection, including material composition analysis, dimensional verification, surface finish testing, and mechanical performance testing, to fully comply with ASTM B444 standards and ensure stable and reliable operation in extreme environments.
