What is the structure of the flange gasket

<p>Gasket is the main sealing part of flange connection, so the correct selection of gasket is also the key to ensure that the flange connection does not leak. Do you know what the structure of the flange ring gasket is? Next, we will tell some knowledge about the flange ring gasket&nbsp;structure.</p><p><br></p><p>The structure of the&nbsp;<a href="https://www.jdoseal.com/jdseal-dn40dn50dn100-silicone-rubber-ptfe-the-flange-gasket" rel="noopener noreferrer" target="_blank">flange ring gasket</a></p><p>Flat gaskets used in industry are generally composed of sealing elements and inner and outer reinforcement rings. The sealing element or gasket body is the key part to prevent leakage. The commonly used materials are non-metallic materials, such as flexible graphite, polytetrafluoroethylene, fiber-reinforced rubber-based composite board and so on. In addition, the material of the sealing element can also be rigid or flexible metal, which is usually used in high pressure and temperature situations.</p><p><br></p><p>For sealing elements made of non-metallic materials, metal materials are usually inserted for reinforcement, which also facilitates the manufacturing and processing of sealing elements made of fragile materials such as graphite. The reinforcing material can be a thin metal plate or a wire mesh. The thin metal plate often uses punch holes to improve the reinforcement effect and increase the elasticity, and they are bonded together by adhesive and roll pressing. The sealing element can also be provided with a surface layer or anti-adhesion treatment layer to increase the sealing effect and prevent the flange sealing surface from sticking.</p><p><br></p><p>The outer reinforcement ring or outer ring material is solid metal, and its function is:</p><p>Helps to align the sealing element during installation;</p><p>Prevent the sealing element from being damaged by excessive compression; prevent the gasket from blowing out and reduce the flange rotation.</p><p>The outer reinforcing ring is not in contact with the sealing medium, so it does not require medium corrosion resistance, so it is often made of carbon steel. The outer reinforcement ring can also be integrated with the sealing element, such as a metal tooth gasket and a wave tooth composite gasket.</p><p>The material of the inner reinforcing ring or inner ring contacting fluid should be able to resist the corrosion of the sealing medium. The role of the inner strengthening ring is:</p><p>Prevent the gap between the sealing element and the container or pipe flange to prevent the gap from interfering with the flow of the fluid and the resulting impact of the fluid on the gasket.</p><p><br></p>
