Flanges must be properly aligned to ensure that the pressure is distributed evenly across the entire gasket. Ask your company about their specific criteria.
Potential hazards of faulty flange joints are numerous: from instant bodily injuries, damage to installations and pollution of the environment. Therefore ensure at all times that you are qualified to work on flanges, that you are using the proper PPE and the prescribed tools.
