Toll-Free: In order to seal precisely, metal gaskets must most of the time be compressed at a higher stress. Also, in some cases, a sealant must be applied right on the gasket in order to secure a leak-free seal. A gasket is a crucial element in many manufacturing processes, as they are obtainable in numerous specifications.
Gasket material is chosen for an installation on the basis of the features of the material, such as its resistance to chemicals, temperatures or temperature fluctuations , pressures, acids, gases, and sometimes electromagnetic or electrical forces. Gaskets are very common components and can be found in cars, trains, planes, boats, electrical equipment, pumps, and many more applications.
A gasket material provides the capacity to resist some of the most difficult environments for industrial sealing products, these include:. We use cookies to improve your experience. By your continued use of this site you accept such use. For more information, please see our privacy policy.

There are other shock forces that may be created due to sudden changes in temperature and pressure. Creep relaxation is another factor that may come into the picture. Material and Properties 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.
The optimum gasket material needs to have the following characteristics. Chemical resistance of PTFE. Temperature or heat resistance of graphite. Strength or mechanical properties of steel. Zero seating stress of soft rubber. Temperature of the media to be contained Pressure of the media to be contained Corrosive nature of the application Criticality of the application Flange configuration Hot Compression Test An important characteristic for industrial gaskets is their capacity for tolerating compressive loads.
Is a Gasket Necessary? Types of gaskets As per material of construction, gaskets can be divided into three main categories: Non-Metallic — Non Metallic gaskets are are usually composite sheet materials which are used in low to medium pressure services. With careful selection these gaskets are not only suitable for general service but also for extreme chemical services and temperatures. Examples are elastomers, cork, compressed fibre sheets, poly tetra fluoro ethylene PTFE , Bi-axially orientated reinforced PTFE, graphite, thermiculite, and insulating gaskets etc.
ASME B Semi-Metallic — Semi Metallic gaskets are composite of both metallic and non-metallic materials. The metal provides the strength and the resilience of the gasket and the non-metallic component provides the conformable sealing material.
These gaskets are suitable for low and high pressure and temperature applications. A wide range of materials is available. Examples are spiral wound gaskets, gaskets with covered serrated metal core, metal jacketed gaskets, and metal reinforced gaskets etc. These gaskets require a much higher quality of the sealing surface than non-metallic gaskets. Except for weld ring gaskets, high loads are required to seat metallic gaskets, as they rely on the deformation or coining of the material into the flange surfaces.
Examples are ring type joints, lens rings, weld rings, and solid metal gaskets etc.
