ASTM B163 ASME SB163 Nickel 200 UNS N02200 DIN 2.4066 Seamless Tube
UNS N02200 | DIN 2.4066 | Pure Nickel Tubing
ASTM B163 / ASME SB163 Nickel 200 seamless tubes, manufactured from UNS N02200 (DIN 2.4066), are commercially pure nickel tubes known for their excellent corrosion resistance, outstanding electrical and thermal conductivity, and superior resistance to caustic alkalis. These seamless nickel tubes are widely used in chemical processing, heat exchangers, electronics, and power generation industries.
Nickel 200 tubes are especially suitable for reducing environments and applications requiring high material purity.
We are a professional manufacturer of ASTM B163 UNS N02200 Seamless tube in China.
What Is ASTM B163 / ASME SB163?
ASTM B163 (adopted by ASME as SB163) is the standard specification for seamless nickel and nickel alloy tubes intended for heat exchangers and condensers.
