Nickel 200 instrumentation tubes are precision-engineered tubular components made from commercially pure nickel (minimum 99.6% Ni). These tubes are designed specifically for use in instrumentation and control systems, where material integrity, corrosion resistance, and high conductivity are essential. Nickel 200 is known for its excellent performance in reducing and neutral environments, particularly in applications involving caustic alkalis like sodium and potassium hydroxide.
One of the key advantages of Nickel 200 instrumentation tubes is their superior corrosion resistance, especially in strongly alkaline conditions. Unlike many other metals, Nickel 200 maintains its structural stability and resists degradation in highly caustic media, making it ideal for chemical and petrochemical processing applications. However, it is not recommended for use in strongly oxidizing environments, such as those containing nitric acid, due to its limited resistance in such conditions.
Nickel 200 tubes are typically produced to comply with international standards such as ASTM B161 and ASTM B163, ensuring high quality and consistency. They are available in seamless or welded forms, with outer diameters ranging from 1/8 inch to 2 inches, and wall thicknesses tailored to specific pressure and application requirements. The tubing is often supplied in annealed condition with surface finishes such as bright annealed or polished to meet cleanliness and precision requirements.
These tubes also offer excellent thermal and electrical conductivity, as well as good mechanical strength across a wide temperature range. Their non-magnetic properties, low gas content, and high purity make them particularly suitable for sensitive instrumentation systems in industries such as electronics, marine, aerospace, and food processing. Nickel 200 is also highly formable and weldable, allowing it to be easily fabricated into complex system designs without compromising performance.
