Nickel 201 Pipes

What is Nickel 201 Pipes?

Nickel 201 Pipes are commercially pure nickel pipes with a low carbon content, offering excellent corrosion resistance and reliable performance in demanding industrial environments. Nickel 201 is the low-carbon version of Nickel 200 and is identified by the UNS designation N02201. Its controlled carbon content makes it particularly suitable for applications where the material may be exposed to elevated temperatures for extended periods.

Nickel 201 provides good resistance to caustic alkalis and useful resistance to neutral and reducing environments. The alloy also offers good thermal and electrical conductivity along with suitable mechanical properties, making it useful for chemical processing, caustic handling, synthetic fiber production, electronics and other specialized applications.

Nickel 201 Pipes can be supplied in seamless and welded forms, depending on the applicable specification and service requirements. They are available in different outside diameters, wall thicknesses, schedules and lengths to suit process piping, fluid transfer, and equipment fabrication requirements.
