Why choose Dongguan hardware for custom metal flat gaskets

A solid metal flat gasket, stamped or turned from a thin metal plate. The materials are widely used. Commonly used materials are mainly aluminum flat gaskets, copper gaskets, stainless steel gaskets, etc., because the sealing depends on the compression and resilience of the material itself, it is selected Generally, a softer material is selected, and a certain pressing force is required to seal, so it is easy to cause interface leakage. Therefore, in most cases, it is recommended to use metal toothed composite gaskets or metal corrugated composite gaskets instead to achieve better Good sealing performance, but its advantage is simple processing and low cost. In most cases, metal flat gaskets can also be used in combination with other non-metallic materials to achieve a better sealing effect. According to different media and working conditions, you can choose flexible graphite, PTFE, non-asbestos board or some other soft metal, stick it on the two sides of the gasket, and take advantage of the tightness of the soft cover layer and the strength and elasticity of the metal. In order to achieve a better sealing effect, in most cases we recommend graphite as the sealing layer. When the medium reacts to graphite or requires a clean environment, we recommend choosing the newly launched expanded tetrafluoroethylene with excellent performance as the adhesive layer, generally not A great pressing force is needed to achieve the sealing effect. If the metal flat gasket has a small size, it is generally regarded as a matching washer in the fastener, which is used to protect the surface of the connected part from the nut and disperse the pressure of the nut on the connected part. The form is also relatively Varieties such as: flat washers-C level, large washers-A and C levels, spherical washers, tapered washers, corrugated washers, etc. Performance characteristics of metal flat gaskets: 1. Simple processing and low cost. 2. Wide range of materials and easy to use. 3. It can be used in high pressure parts, and it can be used in combination with non-metallic materials to achieve better results. Application range: It can be used for almost any standard industrial sealing requirements, from standard pipe connections to sealing doors and sealing of large vessels (heat exchangers, towers, tanks, tanks), the most commonly used are standard bolts and nuts as gaskets. .
