Torqueing and Bolt Tightening Techniques for Lap Joint Flanges
Understanding Lap Joint Flanges
Key components of lap joint flanges:
Flange Ring: The external part that distributes pressure and bolt load.
Stub End: Welded to the pipe; provides fluid contact and corrosion resistance.
Bolts and Nuts: Hold the flange assembly together and compress the gasket to create a leak-proof seal.
Gasket: Sits between flange faces to prevent leakage.
