What are the performance characteristics of metal flat gaskets?

The metal flat gasket is a solid metal gasket, which is made by stamping or turning 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 of the material itself. Elastic, so generally choose a softer material when choosing, and a certain pressing force is required to seal, so it is easy to cause interface leakage, so in most cases, it is recommended to replace with metal tooth-shaped composite gasket or metal corrugated composite gasket Use to achieve better 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 covering 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, cone 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 a gasket. . Hardware has focused on precision stamping for 15 years. It has opened a large workshop of 5000 square meters and many advanced and sophisticated stamping equipment, with a daily production capacity of 3 million stampings. It has 16 strict quality inspections to ensure the quality of each product. If you need to know more About the knowledge of metal flat gaskets, you are welcome to call
