Can anyone tell me why washers are never used with the stud bolts of flange connections?

RE: Flange connections, Petrochemical industry
99.9999+% of the time there is no need for washers as they tend to complicate the makeup of a flanged joint.
They tend to be used on corrupted nut landing areas on the flange that need to refaced.
They are never the right size and thickness for proper bolting.
The reasons for not using them are numerous.
Last but not least they fall from great heights and hit people; ME

Agree for steel flanges. For Plastic Flange connections washers are often required in order to protect the flange blades. For GRE piping systems we do specify washers.
Success,
