N7 Nickel Pipe | 99.9% Pure Nickel Seamless & Welded Pipes

N7 Nickel Pipe is a high-purity nickel pipe with a minimum nickel content of 99.9%, designed for applications requiring excellent corrosion resistance and superior performance in reducing and neutral media. N7 nickel exhibits outstanding resistance to alkaline and neutral salt solutions, organic compounds, and corrosive environments such as caustic alkalis and chlorides.

These pipes are widely used in chemical processing, food handling, synthetic fiber production, marine engineering, and electrical industries. With excellent thermal and electrical conductivity, N7 nickel pipes are also suitable for use in heat exchangers, condensers, and high-purity process equipment.
