Before installing connecting flanges, it is essential to ensure that all the piping components are clean and free of debris. The flange faces should also be clean and free of any dirt, grease, or oil. It is recommended to use a wire brush or sandpaper to clean the flange faces.

Step 2: Aligning the Flange

The next step is to align the flange faces. The flange faces should be aligned with each other to ensure a proper seal. The bolts should be inserted through the bolt holes before the flange faces are aligned.

Step 3: Gasket Placement

After aligning the flange faces, the gasket should be placed on the flange face. The gasket should be the same size as the flange and should fit snugly between the flange faces.

Step 4: Bolt Tightening

The bolts should be tightened gradually and evenly in a crisscross pattern. The bolt tightening should be done in stages, starting from one side of the flange and moving to the other side. The bolts should be tightened until the recommended torque is achieved.
