Incoloy 28 Nickel Based tube
Incoloy 28 Nickel Based tube is a high-performance nickel-iron-chromium based alloy tube. It is strengthened by adding molybdenum (about 3-4%) and copper (about 0.6-1.4%) to improve its corrosion resistance. It also has excellent mechanical properties and high-temperature stability. Incoloy 28 Nickel Based tube has an austenitic structure. It is designed for extremely corrosive environments and performs very well in acidic media containing chlorides and sulfides.
Incoloy 28 Nickel Based tube is widely used in many fields. These include chemical industry (sulfuric/phosphoric acid equipment), petrochemical industry (acid gas pipelines), marine engineering (seawater desalination systems), energy (oil and gas extraction) and environmental protection (flue gas desulfurization devices). Its excellent resistance to chloride/sulfide corrosion, high-temperature stability and mechanical strength make it a key material in extremely corrosive environments. It ensures the long-term safe operation of equipment.
Features of Incoloy 28 Nickel Based tube
Excellent corrosion resistance: Incoloy 28 Nickel Based tube has a high resistance to strong corrosive media such as sulfuric acid, phosphoric acid and wet chlorine gas. It has a strong ability to resist pitting and stress corrosion cracking.
High-temperature performance: Incoloy 28 Nickel Based tube can keep its strength and oxidation resistance below 600°C. It is suitable for high-temperature scenes like heat exchange.
Formability and weldability: Incoloy 28 Nickel Based tube can be formed by conventional processes. It is compatible with TIG and MIG welding technologies. But the heat input needs to be controlled to avoid intergranular corrosion.
Mechanical strength: Incoloy 28 Nickel Based tube has a high yield strength and anti-creep properties. It is suitable for high-pressure environments.
Applications of Incoloy 28 Nickel Based tube
Chemical and petrochemical industries: Incoloy 28 Nickel Based tube is used in acid gas pipelines, reactors and heat exchangers, such as in sulfuric acid production equipment.
Marine and energy fields: Incoloy 28 Nickel Based tube is used in seawater desalination systems and high-chloride environment pipelines in oil and gas extraction.
Environmental protection projects: Incoloy 28 Nickel Based tube is used in key parts of flue gas desulfurization (FGD) systems to resist sulfide corrosion.
Nuclear industry: Incoloy 28 Nickel Based tube is used in the piping of nuclear waste treatment equipment that is resistant to radiation and chemical corrosion.
