Product Introducing:
Graphite 304 Stainless Steel Metal Cladding Gasket is commonly used in equipment that needs to withstand high temperature, high pressure and chemical corrosion environments. The gasket combines the excellent sealing performance of graphite with the strength and corrosion resistance of 304 stainless steel, and can provide efficient sealing under extreme conditions.
1. Composition and construction of Graphite 304 stainless steel metal clad gasket
Graphite layer: Graphite is a material with excellent high temperature resistance, corrosion resistance and good self-lubricating properties. In the gasket, graphite provides excellent sealing performance, especially suitable for high temperature, high pressure and highly corrosive occasions.
304 stainless steel layer: 304 stainless steel is a widely used austenitic stainless steel with good corrosion resistance, strength and toughness. As an outer layer material, it enhances the mechanical strength of the gasket and makes it more stable under high pressure and high temperature environments.
2. Main features of Graphite 304 stainless steel metal clad gasket
High temperature resistance: Graphite can withstand up to 450°C (up to 1000°C under certain conditions), which is very suitable for high temperature working environments.
Corrosion resistance: 304 stainless steel has excellent corrosion resistance and can withstand erosion by a variety of acids, alkalis and chemical media.
High strength: The high strength and good ductility of 304 stainless steel enable the gasket to maintain a sealing effect under high pressure and vibration environments.
Good self-sealing: Graphite has the characteristics of self-sealing, which can fill the tiny gaps on the contact surface and reduce the risk of leakage.
Anti-aging: Graphite is not easy to age and can maintain good sealing even in high temperature environments for a long time.
Strong adaptability: The combination of graphite and stainless steel makes the gasket show strong adaptability under extreme working conditions, especially suitable for high pressure, high temperature and corrosive environments.
3. Scope of application and industry
Graphite 304 stainless steel metal-coated gaskets are widely used in industrial fields that require high sealing performance and corrosion resistance and high temperature resistance. The specific application scope includes but is not limited to the following industries and scenarios:
Chemical industry: In chemical reactors, pipelines, valves and pumps and other equipment, graphite 304 stainless steel coated gaskets can be used to prevent the leakage of toxic and corrosive chemicals and protect equipment from corrosion.
Oil and gas industry: In high temperature and high pressure environments such as oil refining and natural gas transmission, this gasket can be used to seal pumps, valves, pressure vessels and other equipment.
Power industry: In boilers, steam systems and heat exchangers, Graphite 304 stainless steel metal-clad gaskets are used for high temperature, high pressure and steam sealing.
Food and pharmaceutical industry: The non-toxicity and high corrosion resistance of graphite materials make it widely used in the food and pharmaceutical industries to ensure the hygiene and sealing performance of equipment.
Marine engineering: Due to its corrosion resistance, Graphite 304 stainless steel metal-clad gaskets are suitable for sealing equipment such as offshore platforms and ships.
Automotive manufacturing: In the sealing of high temperature parts such as engines and exhaust systems, graphite 304 stainless steel gaskets can ensure stable sealing.

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.
