Product Introduction

Products Description

 

Nickel Alloy Pipe 200 201

 

Our Advantages 

 

  • Alkali Resistance: Our Nickel Alloy Pipe 200/201 is resistant to caustic soda and potash solutions even at high temperatures. Nickel 201's low carbon content minimizes contamination, making it ideal for high-purity chemical production.
  • High Electrical Conductivity: Nickel 200/201 offers stable and reliable conductivity, which can withstand temperature fluctuations without significant changes in electrical properties, making it ideal for the manufacture of electronic components and batteries.
  • Safety: With a nickel content of ≥99.0%, Nickel 200/201 does not leach harmful substances and is non-toxic and suitable for applications in the pharmaceutical industry.

 

application areas

 

  • Chemical and petrochemical industries: alkali evaporators, reactors, heat exchanger piping, and equipment and pipelines for handling halogens and organics.
  • Power generation and heat transfer: condenser heat exchanger tubes and cooling circuits for corrosive media.
  • Electronic and electronic industries: electronic tube components, waveguides, and high-purity semiconductor gas delivery pipes.
  • Aerospace: rocket engine propellant delivery systems and aircraft hydraulic piping.
  • Marine engineering: seawater desalination plants and shipbuilding.
