A gasket is used to seal between the flange faces to prevent leakage under compression or corrosion. As the flanges are impossibly manufactured perfectly smooth, a gasket is needed to apply to provide the necessary seal. It is an ideal part to fill the deformities and connect two mating surfaces together.
Usually, flange gaskets are cut from sealing sheets such as rubber, metal, PTFE or graphite. While some other gaskets are made from metallic material with a non-metallic material to provide a functional seal, like a spiral wound gasket. What applications a gasket is used for?As a professional gasket supplier, we produce gaskets that have a wide application, including in the oil, gas and petrochemical industries, food & beverage, power generation, mining, military, aerospace, pharmaceutical, filtration, sanitary process industries, and nuclear installations, etc. The gaskets are all manufactured from Ginseal gasket maker accordingly to ASME B16.20 and API or EN1514 or JIS standard. We also provide custom gaskets service with free samples. As of the best China gasket manufacturers, our gasket and sealing products have been exported to the USA, UK, Canada, Germany, Australia, Japan, and other more than 40 countries,obtained the trust and recognition of local customers.
How to choose a suitable gasket?To get an adequate sealing, we need considering how to choose a suitable gasket from the best gasket manufacturers based on the below factors:
Material Selection: Gasket material should be chosen to withstand a temperature/pressure range and the chemical properties of the fluid media under operation.
Seating Stress: we must give a suitable pressure to seat the gasket correctly. The pressure should be limited in case of the crush of gaskets by excessive compression, at the same time the gaskets can fill the flange imperfections under the compression.
Sealing Force: To avoid any leakage, there should be enough pressure on the sheet gasket to keep it in sufficient contact with the flange faces. Ginseal Gasket Manufacturer Finish: The flange finish surface should be compatible with the gasket, in this way the gaskets can provide a good seal.
