Copper gasket is a kind of metal coated gasket, non-magnetic, conductive, thermal conductivity, corrosion resistance is very good. Therefore, heat exchangers, pressure vessels and other high temperature and high pressure sealing parts can be used to effectively prevent the gasket, the erosion of the media The copper gasket is usually sealed with a threaded place. The sealing principle is that the two bonding surfaces press the deformation of the copper pad so that the two surfaces of the copper pad are in close contact with the two bonding surfaces without the slightest gap, resulting in a sealing effect The In order to achieve the sealing effect, usually before the use of annealing, the purpose is to make the copper seal soft, in order to achieve better sealing effect, but also to effectively prevent the gasket, the erosion of the media So it is generally used in the joint with the installation of the slot, such as: male and female with the flange, the valve cover, pressure gauges, etc.
