The surface of the metal wound gasket of the gasket is not allowed to have scratches, voids, irregularities and rust spots that affect the sealing performance. The non-metallic strip on the surface of the metal wound gasket should be uniform, and the metal strip should be appropriately raised. The texture between the layers should be clear, but the metal strip should not be exposed. The spacing of the solder joints of the metal wound gasket should be uniform, and there should be no defects such as unfusion or over-melting. The surface of the reinforcing ring shall be free of defects such as burrs, unevenness, rust spots, etc. The spacing between the upper and lower sealing surfaces of the metal wound gasket main body and the upper and lower surfaces of the reinforcing ring shall be equal. The inner side of the reinforcing ring and the metal wound gasket body shall be tightly fixed and shall not be loosened; The outer reinforcement ring and the gasket body should be positioned and loosened properly.
