How to Choose the Right Hastelloy Flanges

Select the appropriate flange type and size: Select the correct kind of Hastelloy flange (for instance, weld neck, slip-on, socket weld) according to what your piping system needs. Verify that the flange dimensions correspond to the pipe dimensions and satisfy the specifications of your application.
Prepare the flange surfaces: Carefully clean the mating surfaces of the flanges and pipes to eliminate any dirt, debris, or contaminants that might weaken the seal. Confirm that the flange faces are flat and free of imperfections to guarantee proper alignment and sealing.
Install gaskets: Position the suitable gasket material (for example, spiral wound, flat ring, or RTJ gasket) between the flange faces to deliver a leak-tight seal. Pick a gasket material that works with Hastelloy and the fluid or gas moving through your system.
Align the flanges: Line up the bolt holes of the mating flanges and pass the bolts or studs through the holes. Employ alignment tools or jacks to secure proper alignment and avoid distortion or misalignment while tightening.
Tighten the bolts: Progressively tighten the bolts or studs in a crisscross pattern with a calibrated torque wrench to the specified torque values. Follow the torque sequence recommended by the flange manufacturer to spread the load evenly and reach a uniform seal.
Inspect for leaks: Once the bolts are tightened, visually check the flange connection for any indications of leaks, such as fluid seepage or gasket extrusion. Carry out a pressure test if required to confirm the integrity of the flange joint under operating conditions.
Monitor for corrosion: Routinely examine Hastelloy flanges for indications of corrosion, erosion, or degradation, particularly in aggressive environments. Apply corrosion prevention measures such as protective coatings or cathodic protection to prolong the service life of the flanges.
Follow manufacturer guidelines: Follow the flange manufacturer’s installation, maintenance, and operating guidelines to secure optimal performance and durability of Hastelloy flanges in your piping system.
