Factors influencing performance of Gaskets
The purpose of a gasket is to create a positive seal between stationary parts and then maintain that seal over a length of time. Just like every item, gaskets also have a life period and when that life is over, a gasket should be easily removable in order to be replaced. So, what are the factors that influence the performance of a gasket.

Surface condition of sealing surface

Soft gaskets are kind of insensitive to the surface condition because of its easy deformation, while hard ones are greatly affected by the surface condition. Smooth surface is beneficial to sealing.

Properties of the fluid

Higher the viscosity of the fluid, easier it is to seal because of its poor fluidity. Liquid is easier to seal than the gas due to its higher viscosity. Saturated vapor is easier to seal than superheated vapor since it condensates droplets and blocks the passage between the sealing surfaces.

Contact width of sealing surface

Larger the contact width between sealing surface and gasket cuases longer path of fluid leakage, hence greater loss of flow resistance, thus conducive to sealing. But under the same compression force, larger contact width would mean lower sealing pressure. So, appropriate contact width should be sought according to the material quality of the seals.

Temperature of the fluid

Temperature affects the viscosity of the liquid, thereby affecting the sealing performance. A rise in temperature causes viscosity of the liquid to decrease and viscosity of the gas to increase. 

Material of gaskets and fillers

The corrosion resistance, heat resistance, compactness and hydrophilicity of sealing materials surely affect the sealing. Soft materials are prone to elastic or plastic deformation under preloading force, thus blocking the passage of fluid leakage, thus conducive to sealing; but soft materials generally can not withstand the role of high-pressure fluid. 

Influence of external conditions

Conditions like vibration of pipeline system, deformation of connecting components, offset of installation position produce additional force on the seal, thus causing adverse effects on the seal. Hence, the above factors must be carefully considered.

Storage of gaskets also needs some considerations to save them for getting useless. Read here how - How to store the gaskets to maintain their shelf life.



Industrial Gaskets and Seals - Whats the difference?

When being a part of construction and production industry, the terms flanges, gaskets. seals are a common heard. Even though these hold an equal importance in small machines and tools of day to day living also, industrial use of these is mammoth

Asbestos Was The Choice in Sealing

Asbestos Was The Choice in Sealing

Asbestos is a mineral that occurs abundantly all around the world. In 1899, an Austrian engineer named Richard Klinger developed the first compressed asbestos sheet gasket material, and in 1912, the Flexitallic Gasket Company began selling the

A Peep To Know What Are Spiral Wound Gaskets

The spiral wound gaskets are the most commonly used gaskets for critical applications. These gaskets are designed in a way that can effectively withstand the change in pressure and temperature during the sealing process.  Spiral wound gaskets

Lathe Cut Gaskets - What Makes Them The Choice

Hearing of sealing mechanical objects, we think of O rings automatically. Another very practically usable name that is heard of is the Lathe Cut Gasket. These are manufactured from a tube of rubber. During production, a mandrel is inserted into

Ready Cut Gaskets and Sheets in North India

Die cut gaskets serve as a seal between two different surfaces. When enough bolt load creates a compressive force, a ready cut gasket seals the gap between the surfaces. The seal also fills imperfections on the mating surfaces, which can solve
