ASTM B161 Nickel 200 201 Seamless Pipe

May 07, 2024

Nickel alloy seamless pipes, devoid of any seams or welds, are produced through either cold drawing or hot rolling processes. These pipes are typically crafted using ASTM B161 Nickel 200 and Nickel 201, which consist of commercially pure wrought nickel. This material selection delivers superior mechanical properties and excellent corrosion resistance, particularly in reducing environments, along with commendable electrical conductivity. Due to these attributes, nickel alloy seamless pipes are highly preferred in applications demanding high temperature and corrosion resistance, such as in chemical processing and petrochemical processing industries.
