Oil and Gas as a major source of global energy, the selection of corrosion resistant materials used in its producing and transporting is critical. The oil and gas industry relies heavily on nickel alloys for the production of equipment that can withstand harsh environments. These alloys are used in oil and gas pipelines, pumps, valves, and other equipment that is exposed to high temperatures and corrosive fluids.They offer long term corrosion resistance to high H2S and CO2, high pressures, and high temperatures. They are also the most resistant to corrosion and cracking caused by free sulfur.
