Nickel Alloy Tube / Nickel Pipe

Nickel alloy tubes are precision-engineered solutions designed for extreme environments. Commonly used grades include Inconel 625 (UNS N06625), Hastelloy C276 (UNS N10276) , and Monel 400 (UNS N04400) , Copper Nickel Tube. These tubes combine outstanding corrosion resistance, high-temperature stability, and superior mechanical strength, making them critical for demanding applications in chemical processing, aerospace, oil & gas, and power generation.

Key Features

• Corrosion Resistance: Excellent resistance to acids (HCl, H₂SO₄), chlorides, and seawater, minimizing pitting and stress corrosion cracking.
• Thermal Performance: Operates continuously at 600–1100°C (depending on grade), with creep resistance under prolonged thermal stress.
• Mechanical Durability: High tensile strength (≥700 MPa) and toughness for high-pressure/vibration environments.
• Customization: Available in seamless/welded forms, OD 6–300 mm, wall thickness 0.5–25 mm, with cold-drawn or annealed finishes.
