Gasket
Gaskets Details
A gasket is a sealing component used to fill the gap between two or more surfaces, typically to prevent leakage of fluids or gases into or out of the joined parts when they are compressed.
Gasket Parameters
Once it is established that a gasket is the suitable choice for an application, rather than a shim or o-ring, several additional factors need to be considered to select the ideal design. While there are various types of gaskets, many have similar characteristics and can perform comparable functions. Some of the most commonly used types of gaskets include:
Flat Gaskets
Flat gaskets are the simplest type, typically made from materials such as rubber, cork, or paper. They are primarily used to seal static joints where two flat surfaces come together, preventing leakage of fluids or gases. These gaskets are widely used in industries like automotive, manufacturing, and plumbing.
O-Ring Gaskets
O-ring gaskets are circular in shape and are one of the most common types used in dynamic sealing applications, where movement occurs between the two mating parts. These gaskets are typically made from elastomers like rubber, silicone, or nitrile, and are ideal for creating seals under compression. They are commonly used in hydraulic and pneumatic systems.
Spiral Wound Gaskets
Spiral wound gaskets are made from alternating layers of metal and non-metallic filler material, such as graphite or PTFE. This construction allows them to maintain a tight seal even under extreme pressure and temperature conditions. These gaskets are widely used in industries such as oil and gas, chemical processing, and power generation.
Ring Joint Gaskets
Ring joint gaskets are designed to provide a high-strength seal for flanged connections in high-pressure and high-temperature applications. They are typically made from metal and are commonly used in the oil and gas industry, particularly in drilling and refining operations. These gaskets can withstand harsh conditions and maintain a reliable seal.
Corrugated Gaskets
These gaskets feature a corrugated metal core, which provides flexibility and compressibility for sealing. They are typically used in heavy-duty applications like boilers, heat exchangers, and pipelines, where there are extreme pressure and temperature fluctuations. Their design allows them to create a reliable seal even under dynamic pressure
Compressed Non-Asbestos Gaskets
Made from a mix of aramid fibers and elastomers, these gaskets offer a safe alternative to asbestos gaskets, which have been phased out due to health concerns. They are used in a variety of industries where high chemical and temperature resistance is needed, including in power plants and refineries.
Camprofile Gaskets
Camprofile gaskets are made from a metal core, often stainless steel, with soft sealing material inserted into the grooves. This design ensures excellent sealing performance and resistance to extreme pressure. They are commonly used in applications involving flanges, heat exchangers, and valves.
Gasket Seals (Cork, Rubber, or Silicone)
Gaskets made from materials like cork, rubber, or silicone are used for applications that require flexibility and ease of installation. These materials help in creating a tight seal while absorbing vibrations and compensating for misalignment between mating parts. They're often used in automotive engines, HVAC systems, and food processing.
Metal Gaskets
Metal gaskets, typically made from stainless steel or other alloys, are designed to provide excellent sealing in environments with high heat and pressure. These gaskets are often used in industries such as aerospace, chemical processing, and heavy manufacturing, where durability and resistance to extreme conditions are paramount.
Klinger® Gaskets
Klinger® gaskets are known for their high resistance to chemical corrosion, high pressure, and temperature variations. These gaskets are commonly used in the chemical and petrochemical industries, where they provide reliable sealing for pipes, valves, and flanges that handle aggressive substances. Their construction typically includes a combination of graphite and other materials for enhanced performance.
