How to Choose the Right Hastelloy Flanges

Select the appropriate flange type and size: Choose the right type of Hastelloy flange (e.g., weld neck, slip-on, socket weld) based on your piping system requirements. Ensure the flange size matches the pipe size and meets the specifications of your application.
Prepare the flange surfaces: Thoroughly clean the mating surfaces of the flanges and pipes to remove any dirt, debris, or contaminants that could compromise the seal. Ensure the flange faces are flat and free of defects to ensure proper alignment and sealing.
Install gaskets: Place the appropriate gasket material (e.g., spiral wound, flat ring, or RTJ gasket) between the flange faces to provide a leak-tight seal. Choose a gasket material compatible with Hastelloy and the fluid or gas transported in your system.
Align the flanges: Align the bolt holes of the mating flanges and insert the bolts or studs through the holes. Use alignment tools or jacks to ensure proper alignment and prevent distortion or misalignment during tightening.
Tighten the bolts: Gradually tighten the bolts or studs in a crisscross pattern using a calibrated torque wrench to the specified torque values. Follow the recommended torque sequence provided by the flange manufacturer to distribute the load evenly and achieve a uniform seal.
Inspect for leaks: After tightening the bolts, visually inspect the flange connection for any signs of leaks, such as fluid seepage or gasket extrusion. Perform a pressure test if necessary to verify the integrity of the flange joint under operating conditions.
Monitor for corrosion: Regularly inspect Hastelloy flanges for signs of corrosion, erosion, or degradation, especially in aggressive environments. Implement corrosion prevention measures such as protective coatings or cathodic protection to extend the service life of the flanges.
Follow manufacturer guidelines: Adhere to the flange manufacturer’s installation, maintenance, and operating guidelines to ensure optimal performance and longevity of Hastelloy flanges in your piping system.
