Nickel Alloy Buttweld Fittings
Nickel Alloy Buttweld Fittings
Nickel alloy buttweld fittings are highly specialized piping components designed for superior performance in aggressive and demanding environments. Manufactured from nickel-based alloys such as Inconel, Monel, Hastelloy, and Nickel 200/201, these fittings are known for their outstanding resistance to corrosion, heat, and pressure.
They are widely used in industries where conventional stainless or carbon steel fittings may fail, such as chemical processing, petrochemical, power generation, marine, and aerospace. The buttweld joint provides a strong, leak-proof connection, ensuring long-term reliability even under extreme operating conditions.
Types of Nickel Alloy Buttweld Fittings
1. Nickel Alloy Elbows
Designed to change the direction of piping at angles like 45°, 90°, and 180°.
Available in long radius and short radius designs.
Ideal for high-pressure and high-temperature flow systems.
2. Nickel Alloy Tees
Used to combine or divide fluid flow.
Equal Tee: Maintains equal diameter across all three outlets.
Reducing Tee: Connects pipes of varying diameters.
Ensures smooth flow distribution.
3. Nickel Alloy Reducers
Connects pipes of different sizes in a piping system.
Concentric Reducer: Maintains a common centerline for vertical piping.
Eccentric Reducer: Offset design prevents air pockets in horizontal piping.
4. Nickel Alloy Caps
Used to seal off the ends of pipes.
Protects the piping system during testing or when a line is no longer needed.
5. Nickel Alloy Stub Ends
Works with lap joint flanges.
Cost-effective solution for flanged connections, allowing for easy disassembly.
6. Nickel Alloy Bends
Provides customized directional flow with smooth bending.
Reduces pressure loss in complex piping layouts.
7. Nickel Alloy Cross
Four-way fitting used in applications requiring multiple flow directions.
Common in high-pressure distribution systems.
