Flat Facing of Circular Surfaces

Restoration of gasket support seats
In cases where it is necessary to restore the damaged sealing seats of the flanges of pipes or pressure equipment (eg heat exchangers, reactors, columns, tanks) it is possible to use portable machine tools.

VED portable machine tools, to be anchored inside or outside the flange, are able to restore sealing seats of any type up to a diameter of 6000 mm, obtaining surface finishes from Ra 12.5 μm to Ra 0.8 μm and creating concentric and phonographic lines.
