What are the different types of gaskets?
An understanding of the different types of gaskets can help you ensure you are purchasing the gasket that is best suited to your specific application.
- Envelope Gasket.
- Flat Metal Gasket.
- Non-Asbestos Sheet Material Gasket.
- Ring Type Joint Gasket.
- Kammprofile Gasket.
- Spiral Wound Gasket with an Inner Ring.
What is CAF gasket?
CAF/Non Asbestos Gaskets are die cut or circle cut from compressed asbestos fibre / non asbestos jointings which are manufactured from carefully selected fibre intimately blended with suitable heat resistant binders etc. and vulcanised into sheets of homogenous compositions and uniform thickness.
What type of gasket is commonly used to seal high pressure?
High Pressure Gaskets
| Gasket Material | Maximum Pressure |
|---|---|
| Rubber, Nitrile, EPDM, BUTYL, Neoprene, Viton and Silicone. | 150 psi |
| Non-Asbestos Fibre | 750 – 1500 psi (50 – 100 Bar) |
| Non-Asbestos with SS Tanged Insert | 2500 psi (172 Bar) |
| Compressed Graphite – tanged Stainless Steel Insertion | +2800 psi (193 Bar) |
What is a gasket used for?
A gasket stores energy, like a spring, and seals two mating surfaces that fail to perfectly meet. Wikipedia: “Fills the space between two objects, generally to prevent leakage between the two objects while under compression.
Which material is used for gaskets?
Gaskets are normally made from a flat material, a sheet such as paper, rubber, silicone, metal, cork, felt, neoprene, nitrile rubber, fiberglass, polytetrafluoroethylene (otherwise known as PTFE or Teflon) or a plastic polymer (such as polychlorotrifluoroethylene).
Where are metal gaskets used?
Metallic Gaskets are used for sealing higher temperature and pressure applications, where non-asbestos materials will fail. Typical applications are for heat exchangers, compressors, condensers, pumps, and valves.
What is neoprene gasket?
Properties of Neoprene Gasket Material Neoprene—also referred to by the generic name polychloroprene—is a synthetic rubber manufactured by polymerizing chloroprene. It demonstrates several characteristics that make it suitable for gasketing applications, such as: Elasticity and flexibility.
What is RTJ gasket?
Ring type joint gasket (RTJ Gasket) is a high integrity sealing gasket, high temperature and high pressure gasket for applications in petroleum industry, oilfield drilling, pressure vessels joints, pipes and valves etc from Goodrich Gasket Pvt. Ltd.
What are the different types of flange gaskets?
The three primary types of Flange Gaskets are Non-metallic, Semi metallic and Metal Gaskets. The Non-metallic Flange Gaskets are used in low pressure, low temperature and noncritical service applications.
What is a PTFE gasket?
PTFE, Unfilled Gaskets (Virgin PTFE® Gaskets) It is made directly from the resin producer and has never been processed into a shape. It possesses the highest physical and electrical insulation properties and has increased resistance to creep (compression) under load.
How are gaskets made?
Gaskets created from rubber come to the factory as large flat pieces of material, often times rubber. Next, using a CNC die cutting machine, gaskets are created as the machine stamps them out of the larger sheet. After the gaskets are produced, they are packaged and shipped all over the world.
What is the difference between gasket and seal?
Generally speaking, gaskets serve as a static seal between flat surfaces, such as joints, while seals are used in more dynamic environments between active components such as rotating shafts, pumps, and engines.
Common types of gaskets include: Rubber is a soft gasket material. A wide range of elastomers can be used, such as neoprene, nitrile, EPDM and natural rubber. Rubber gaskets are used in a wide range of applications such as pipe gaskets, heat exchangers, and manways.
What type of gasket is used in an oil pan?
Embossed steel or shim type gasket is generally used on I-head engine. Shimbestos is a combination of thin steel heat shield on one side and a high resilient metal-reinforced asbestos on the top side. Felbestos is made of perforated steel sandwich between two asbestos sheets. Oil pan gaskets are made of three different materials:
What are rubber gaskets used for?
Rubber gaskets are used in a wide range of applications such as pipe gaskets, heat exchangers, and manways. Non-asbestos gaskets are manufactured from a compressed fibre with an elastomer binding; and are used in many applications such as acid, steam, oil and water.
What is the function of gasket in process piping?
The primary function of gaskets is to seal the irregularities of each face of the flange so that there will be no leakage of the service fluid from the flange joint. There are three types of gaskets used in process piping.
