Nickel Flanges
Nickel Flanges are essential components in piping systems, designed to connect pipes, valves, pumps, and other equipment with secure, leak-proof joints. Manufactured primarily from Nickel 200 and Nickel 201, these flanges offer exceptional strength, corrosion resistance, and thermal stability, making them suitable for industries that demand reliable performance in challenging environments.
With their high nickel content (minimum 99%), these flanges are resistant to various corrosive agents, especially caustic alkalis, neutral salts, and acidic environments. They also maintain excellent ductility, electrical conductivity, and thermal stability, ensuring consistent performance across a wide range of temperatures.
Chemical Composition of Nickel Flanges
The chemical balance of nickel provides superior resistance to corrosion and oxidation. The key difference between Nickel 200 and Nickel 201 lies in their carbon content, which influences their suitability for different temperature conditions.
Nickel 200
Carbon: 0.15% max
Manganese: 0.35% max
Silicon: 0.35% max
Sulfur: 0.01% max
Copper: 0.25% max
Iron: 0.40% max
Nickel: 99.0% min
Nickel 201
Carbon: 0.02% max
Manganese: 0.35% max
Silicon: 0.35% max
Sulfur: 0.01% max
Copper: 0.25% max
Iron: 0.40% max
Nickel: 99.0% min
Nickel 200 is a commercially pure wrought nickel suitable for most general applications, whereas Nickel 201, with its lower carbon content, prevents graphitization and is better suited for high-temperature environments.
Mechanical Properties of Nickel Flanges
Nickel flanges are valued for their strength, toughness, and ductility. Both Nickel 200 and Nickel 201 offer nearly identical mechanical characteristics, ensuring durability under high stress and thermal fluctuations.
