Pure Nickel Seamless Tubes & Pipes: Unmatched Purity and Corrosion Resistance for Critical Applications
Pure Nickel Tubes and Pipes (UNS N02200/N02201) are high-purity, non-alloyed solutions designed for environments demanding exceptional corrosion resistance, thermal conductivity, and electrical performance. With a minimum nickel content of 99.6%, these tubes resist caustic alkalis, hydrofluoric acid, and reducing atmospheres up to 600°C. Their low carbon content (<0.02% for N02200) prevents carbide formation, ensuring stability in chlorine-rich and high-temperature steam applications. Cold-worked and stress-relieved per ASTM B161 and B163 standards, these tubes achieve tensile strengths up to 380 MPa with 35% elongation, ideal for heat exchangers, chemical processing, and electronics manufacturing. From molten salt reactors to semiconductor fabrication, Pure Nickel Tubing delivers reliability where material integrity is non-negotiable.

Food & Pharma: Ultra-pure fluid transfer systems for pharmaceutical-grade NaOH solutions.
Pure Nickel Tubes & Pipes: Frequently Asked Questions
Q1: Why choose Pure Nickel over Monel 400 in hydrofluoric acid (HF) service?
A: Pure Nickel’s 99.6%+ purity eliminates copper content, reducing HF corrosion rates by 50% compared to Monel 400 (per ASTM G31 testing).
Q2: Can Pure Nickel Tubing withstand thermal cycling in molten salt applications?
A: Yes. Its low thermal expansion coefficient (13.3 μm/m·K) ensures dimensional stability through 500+ cycles at 900°C (ASTM E228).
Q3: What welding techniques preserve Nickel 200/201’s corrosion resistance?
A: Use AWS A5.14 ERNi-1 filler with TIG welding under argon shielding. Post-weld annealing at 650°C removes residual stresses.
Q4: Are ultra-thin Pure Nickel Tubes available for electronics cooling?
A: We supply precision-drawn tubes with 0.5 mm walls and ±0.05 mm tolerance, polished to Ra ≤0.4 μm for microchannel applications.
Q5: How does Nickel 201 differ from Nickel 200 in high-temperature service?
A: Nickel 201 (UNS N02201) has lower carbon (≤0.02%) to prevent embrittlement above 315°C, ideal for continuous furnace components.
