How to Choose the Right Nickel Alloy Flanges

Select the Right Alloy Grade: Choose the appropriate nickel alloy grade based on the specific requirements of your application, considering factors such as corrosion resistance, high-temperature strength, mechanical properties, and compatibility with the fluid or environment.
Verify Flange Specifications: Ensure that the selected nickel alloy flanges meet the required specifications and standards for your application, including size, dimensions, pressure ratings, face type (e.g., raised face or flat face), and flange type (e.g., weld neck, slip-on, socket weld).
Inspect Flanges for Defects: Before installation, inspect the nickel alloy flanges for any defects, damage, or irregularities, such as cracks, pits, or surface imperfections that may affect performance or integrity.
Prepare the Piping System: The piping system is cleaned, and the pipe ends are deburred to ensure proper fit and alignment with the flanges. Remove contaminants, dirt, or debris that may impair the sealing surface.
Install Gaskets: Place appropriate gaskets between the mating surfaces of the flanges to create a leak-tight seal. Choose gasket materials compatible with the application’s fluid, temperature, and pressure conditions.
Align Flanges: Align the flanges and pipe ends carefully to ensure proper alignment and engagement of bolt holes. Use alignment tools or jigs if necessary to achieve accurate alignment and prevent misalignment.
Install Bolts and Nuts: Insert bolts through the bolt holes of the flanges and tighten nuts evenly and progressively in a crisscross pattern to apply uniform pressure and create a tight seal. Follow the recommended torque values specified for the flange and gasket materials.
Check Alignment and Tightness: After installation, check the alignment of the flanges and bolts to ensure they are properly aligned and tightened. Verify that the gaskets are seated correctly and there are no visible leaks or gaps.
Perform Pressure Test: Conduct a pressure test on the piping system to verify the integrity and leak-tightness of the nickel alloy flanges under operating conditions. Follow industry-standard procedures and safety protocols for pressure testing.
Monitor Performance: Regularly monitor the performance of the nickel alloy flanges and inspect for any signs of leakage, corrosion, or damage. Implement preventive maintenance measures to ensure the continued reliability and integrity of the piping system.
