Application
Chemical Processing: Nickel and nickel-cobalt alloys are known for their excellent resistance to various chemicals. Tubes made according to ASTM B626 are often used in chemical processing plants for piping systems, heat exchangers, and reactors, where they encounter aggressive substances like acids, bases, and solvents.
Oil and Gas: These tubes are used in environments prone to corrosion, such as seawater and sour gas conditions, in the oil and gas industry. They suit hydraulic tubing and safety-critical systems in offshore platforms and refineries.
Power Generation: Nickel alloy tubes are crucial in power plants, especially in high-temperature environments. They are used in steam generators, superheaters, and other components where metals must withstand high temperatures and corrosive gases.
Aerospace: The aerospace industry uses ASTM B626 welded tubes in aircraft and spacecraft for systems that require materials with high strength-to-weight ratios and resistance to high-temperature oxidizing environments.
Marine Engineering: Saltwater makes the marine environment highly corrosive. Nickel alloy tubes are used in shipbuilding and marine equipment because they are corrosion-resistant and strong.
Heat Exchangers and Condensers: These tubes are ideal for heat exchangers and condensers because they can tolerate high temperatures and corrosive environments, which are common in many industrial processes.
