Metallic Gaskets
Metallic gaskets are sealing devices made from metal materials such as stainless steel, copper, aluminum, or alloys. They are used in various industrial applications where high temperatures, pressures, or corrosive environments are present. These gaskets provide a strong and reliable seal between two mating surfaces to prevent leakage of fluids or gases.
There are several types of metallic gaskets, each designed for specific applications:
Spiral Wound Gaskets: These gaskets consist of alternating layers of metal and filler material, typically graphite or PTFE (polytetrafluoroethylene). They are suitable for high-pressure and high-temperature applications and can withstand a wide range of operating conditions.
Ring Joint Gaskets: Ring joint gaskets are solid metal gaskets with a specially designed shape, typically oval or octagonal, that fits into the grooves of flanges. They are commonly used in offshore oil and gas industries and high-pressure piping systems.
Metal Jacketed Gaskets: These gaskets feature a metal jacket enclosing a soft filler material, such as graphite or PTFE. They provide excellent sealing performance and are often used in heat exchangers, boilers, and other equipment subjected to high temperatures and pressures.
Corrugated Metal Gaskets: Corrugated metal gaskets have a corrugated or grooved profile that allows them to conform to irregularities in flange surfaces, providing a tight seal. They are suitable for applications with uneven or warped flanges.
Kammprofile Gaskets: Kammprofile gaskets, also known as camprofile gaskets, have a serrated metal core with a soft filler material bonded to each side. They offer superior sealing performance and are commonly used in applications requiring high temperature and pressure resistance.
Metal O-Ring Gaskets: Metal O-ring gaskets are designed in the shape of an O-ring and are typically made from stainless steel or other metal alloys. They are used in applications where traditional elastomeric O-rings cannot withstand the operating conditions.
Metallic gaskets are preferred in applications where resilience to extreme conditions is required, such as in the petrochemical, oil and gas, aerospace, and automotive industries. Proper selection of the gasket type, material, and installation procedures is essential to ensure optimal sealing performance and long-term reliability.
Spiral Wound Gaskets
Spiral wound gaskets are critical components used in industrial applications, particularly in piping systems handling high temperatures, pressures, and corrosive fluids.
They’re crafted by winding metal strips and filler material (usually graphite or PTFE) in a spiral pattern. The metal strip provides structural support, while the filler material ensures flexibility and sealing effectiveness.
These gaskets excel in applications where resilience against extreme conditions is paramount. The spiral design allows them to adapt to flange imperfections, offering superior sealing performance compared to traditional gaskets.
Their versatility makes them suitable for various industries like oil and gas, petrochemical, chemical processing, and power generation. They’re favored for their reliability, longevity, and ability to maintain a tight seal under demanding conditions.
When selecting spiral wound gaskets, factors like temperature, pressure, fluid compatibility, and flange surface finish must be considered to ensure optimal performance and longevity of the sealing system. Regular maintenance and proper installation are also crucial for maximizing their effectiveness.
Camprofile gaskets
Camprofile gaskets are a type of high-performance sealing solution used in industrial applications, especially in environments with high temperatures, pressures, and chemical aggressiveness. They consist of a metal core with concentric serrations on both sides, typically made of stainless steel, surrounded by a compressible sealing material, often graphite or PTFE (polytetrafluoroethylene). This design provides excellent resilience and sealing properties, ensuring leak-free performance even under extreme conditions. Camprofile gaskets are commonly used in industries such as oil and gas, chemical processing, petrochemicals, and refining, where reliable sealing is critical to prevent leaks and ensure operational safety.
Corrugated metallic gaskets
Corrugated metallic gaskets are sealing solutions utilized in high-pressure and high-temperature applications. They feature a corrugated metal core, often made of materials like stainless steel or other alloys, which provides flexibility and resilience. This core is typically surrounded by a soft sealing material, such as graphite or PTFE, to enhance sealing performance. Corrugated metallic gaskets are known for their ability to withstand extreme conditions, including fluctuations in temperature and pressure. They are commonly used in industries such as oil and gas, chemical processing, and power generation, where reliable sealing is crucial to prevent leaks and ensure operational integrity.
Metal jacketed gaskets
Metal jacketed gaskets are robust sealing solutions designed for applications requiring high pressure and temperature resistance. They consist of a metallic outer shell or jacket, usually made of materials like stainless steel, encasing a soft filler material, such as graphite, PTFE, or non-asbestos materials. This construction combines the strength and stability of metal with the sealing properties of the filler material.
Metal jacketed gaskets are often used in industries such as oil and gas, chemical processing, and petrochemicals, where they are employed in flange connections, heat exchangers, and other equipment subjected to extreme operating conditions. Their design allows for reliable sealing even in harsh environments, providing protection against leaks and ensuring operational safety and efficiency.
Rubber-steel gaskets
Rubber-steel gaskets, also known as rubber-coated or rubber-bonded steel gaskets, are sealing solutions that combine the flexibility and resilience of rubber with the strength and durability of steel. These gaskets typically feature a steel core or substrate with a layer of rubber or elastomeric material bonded to one or both sides.
The steel core provides structural support and stability, while the rubber coating offers sealing properties, allowing the gasket to conform to irregularities on mating surfaces and create a tight seal. The rubber layer also helps absorb vibrations and shocks, making these gaskets suitable for applications where dynamic movement or fluctuations occur.
Rubber-steel gaskets find use in various industries, including automotive, machinery, plumbing, and HVAC systems, where they seal joints, flanges, and connections in equipment subjected to moderate temperatures and pressures. Their versatility, resilience, and cost-effectiveness make them a popular choice for sealing applications requiring a balance of strength and flexibility.
Ring Type Joints
Ring Type Joint (RTJ) gaskets are specialized sealing devices used in high-pressure and high-temperature applications, particularly in the oil and gas industry. They are designed for use in flanged connections where standard gaskets may not provide sufficient sealing performance.
RTJ gaskets feature a metallic ring with a hexagonal or octagonal cross-section. The sealing surface of the ring is typically machined to precise tolerances to ensure a tight seal when compressed between two flange faces. These gaskets are commonly made from materials such as soft iron, stainless steel, or other alloys suitable for the intended operating conditions.
RTJ gaskets rely on metal-to-metal contact between the sealing surfaces of the gasket and the flange faces to achieve a secure seal. This design allows RTJ gaskets to withstand extreme pressures and temperatures without deformation or failure.
They are available in various styles and configurations to suit different flange designs and applications. RTJ gaskets are often used in critical applications such as oil and gas pipelines, wellheads, and pressure vessels, where reliable sealing is essential to prevent leaks and ensure operational safety.
