Oval Ring Joint Gasket
means to the metal gasket of oval-shaped section by processing metal materials. It is of pressure energized seal in radial directioMetal ring gasketsare the sealing gaskets of various forms processed from the solid metals of various materials through mechanical cutting by high precision CNC lathes. Featuring small installation areaand high pretension pressure, they are applied in sealing parts of pressure vessels, valves andcylinders in the environments of high temperature, high pressure and high corrosiveness.
Note: When octagonaltype is chosen, the material hardness of the pad should be 15~20HB lower than that of the flange face. It is recommended the pad is not recycled.
