"Joint that comprises a soft material having two opposing and a facial superfu00eccies superfu00eccie edge, and,Processes to improve the sealing of a joint lu2030mina soft and for applying a coating on an edge of the opening of a lu2030mina soft board.A joint that is resistant to failure by compression, even at operating pressures of the flange in the range of about 3000 to about 15.000 psi and having also a good sealing capacity.Comprises a soft material having two opposite surfaces of the gasket face and an opening with an edge perpendicular to the facial surfaces.In which the edge of the opening has a polymer coating (coating) on the edge, to a good sealing capacity.In this configuration, except for the cover, the gasket is coated with another mode, which makes the resistant to compression failure.In settings that require better sealing capacity, at least one of the facial surfaces opposite has coating B of polymer.You can see both the edge and the polymer coating.In which the polymer coating B on facial surfaces opposite leaves the board without coating for sealing capacity in an amount effective to give to the resistance to failure by C.Ompressu00e3o.
