The coated gasket is a product produced by a thin layer of metal-coated soft inorganic sealing filler with high heat resistance. The composite sheet is made of non-metallic materials (flexible graphite, polytetrafluoroethylene, asbestos rubber sheets, ceramic fibers, etc.) on the inside and metal sheets on the outside using a specific cold working process.

READ MOREIn a complex and ever-changing industrial environment, sealing technology is a key link to ensure the stable operation of equipment and prevent medium leakage. Its importance is self-evident. With the advancement of science and technology and the increasing diversification of industrial needs, traditional sealing materials can no longer meet the needs of all application scenarios. Against this background, Metal cladding gaskets came into being. With their unique structure and excellent performance, they have shown strong vitality in many industries such as shipping, electricity, steel, chemicals, machinery, etc., and have become an important part of modern industrial sealing technology.
Metal cladding gaskets are a composite sealing material that tightly combines metal sheets with soft inorganic high-heat-resistant sealing fillers. This unique structural design combines the strength, rigidity and corrosion resistance of metal materials with the flexibility and sealing of soft fillers, achieving complementary advantages and providing an ideal solution for sealing needs under various extreme working conditions. The inner layer is usually made of non-metallic materials such as flexible graphite, polytetrafluoroethylene, asbestos rubber sheet or ceramic fiber, which have good high temperature resistance, chemical corrosion resistance and good compression resilience; the outer layer is covered with a layer of metal sheet, such as stainless steel, aluminum, copper, etc., to enhance the overall strength, wear resistance and impact resistance of the gasket.
Excellent sealing performance: The inner soft filler can fit the sealing surface tightly and effectively fill the tiny gaps. Even under high temperature, high pressure or highly corrosive media, it can maintain a stable sealing effect.
Good adaptability: Metal-clad gaskets are suitable for various irregular or complex flange sealing surfaces. Through cold processing and forming technology, they can accurately match various sealing requirements.
High strength and corrosion resistance: The addition of the outer metal sheet significantly improves the overall strength and corrosion resistance of the gasket, extends its service life and reduces maintenance costs.
Wide range of applications: From low temperature to high temperature (up to hundreds of degrees Celsius), from low pressure to high pressure (including ultra-high pressure environment), metal-clad gaskets can perform well and meet the sealing requirements under different working conditions.
Environmentally friendly: With the improvement of environmental awareness, many metal-clad gaskets use asbestos-free materials as the inner layer, which meets the requirements of modern industry for environmentally friendly products.
In the shipbuilding industry, metal-clad gaskets are widely used in the sealing of hull pipes, valves and pumps, effectively preventing the leakage of media such as seawater and fuel oil, and ensuring navigation safety. In the power industry, the sealing of key equipment such as high-temperature and high-pressure boilers and steam turbines is also inseparable from the support of metal-clad gaskets. In the steel, chemical and machinery manufacturing industries, facing the complex and changing media environment, metal-clad gaskets have become indispensable sealing elements with their excellent sealing performance and corrosion resistance.
With the advancement of Industry 4.0 and intelligent manufacturing, the requirements for sealing technology will become more stringent and diversified. As a representative of advanced sealing materials, the research and development and application of metal-clad gaskets will continue to deepen, and develop towards higher performance, wider scope of application, and more convenient installation and maintenance. For example, improving the performance of the inner layer filler through nanotechnology, or using smart materials to achieve real-time monitoring and self-adjustment of the gasket status will bring new development opportunities for metal-clad gaskets.
As an important innovative achievement in the field of industrial sealing, metal-clad gaskets provide efficient and reliable sealing solutions for multiple industries with their unique structure and excellent performance. With the continuous advancement of technology and the continuous expansion of applications, metal-clad gaskets will play a more important role in ensuring industrial production safety, improving equipment operation efficiency, promoting energy conservation and emission reduction, and become an important force in promoting industrial transformation and upgrading. Industry leaders such as Jiangsu Jintai Sealing Technology Co., Ltd. are leading the metal-clad gasket industry to a higher level through continuous technology research and development and market expansion.
