Nickel is a very versatile Metal and Pure Nickel Welded Pipe is useful in applications involved in Heat transfer, especially Heat exchangers. Nickel has very high heat tolerance and so a Nickel Alloy Pipe manufacturer will recommend using these pipes in those applications where the pipe is to act as a conductor of heat. Nickel is also a conductor of electricity. At temperatures beyond 345°C, nickel tends to exhibit magnetic properties.
