Clean your Flange Faces?
Clean your Flange Faces?
(OP)
This is a simple question but I am not sure what most people do in this situation. Carbon steel flanges come painted. Even the raised spiral face is painted. Do you specify the face to be wire wheel cleaned or washed with a suitable solvent? This would ensure that the gasket has a clean surface to mate to the flange or do you just throw the spiral wound gasket in and go?
Maybe you specify unpainted faces on your flanges?

We always power wire-brush them, but never saw a need to try to clean them further with a solvent.

Normally flange faces are left unpainted per all specifications I came across so far; however, they are protected against corrosion by the use of enviropeel type of products or plastic/wooden coverings to protect flange gramophone from physical damage. If they happen to become rusted due to lack protection, apply wire brushing followed by Acetone/CRC-555 spray and wipe the surface.
