Types of Nickel 200 & Nickel 201 Pipes & Tubes
As leading manufacturers in the industry, we specialize in producing both Nickel 200/201 seamless pipes & tubes and Nickel 200/201 welded pipes & tubes, offering comprehensive solutions for diverse industrial requirements in chemical processing, electronics, food processing, and aerospace applications.
Manufactured from high-purity nickel billets through an extrusion process, these seamless pipes deliver superior strength and exceptional corrosion resistance. The seamless construction eliminates weld seams, making them the preferred choice for critical applications involving high-pressure systems, corrosive chemicals, and high-temperature environments where material integrity is paramount. Nickel 201 seamless pipes are particularly suited for applications above 315°C (600°F) where graphitization could be a concern.
These pipes provide an economical alternative with availability across a broader spectrum of sizes and dimensions. Welded pipes excel in structural applications, low to medium-pressure systems, and general corrosive service conditions where reliable welded joints are essential. Their cost-effectiveness makes them ideal for projects with budget constraints without compromising the excellent corrosion resistance and mechanical properties that nickel alloys are known for. Nickel 201 welded pipes are recommended for high-temperature applications.
