The uses and applications of gaskets
A gasket is basically a type of mechanical seal that fills space between 2 or more comprehensive mating surfaces. They are generally used for preventing leakage into or from the joined objects as they are under compression. The gaskets make it possible for even imperfect mating surfaces present on the machine parts to work efficiently and fill up all the irregularities. Gaskets like flange gaskets are often used in piping systems. They are also used in vehicles like cars, planes, boats and trains as well as for carrying out specialized functions such as managing temperature, pressure and chemical resistance. The distinct properties and features of gaskets make them useful for a wide range of purposes.
There are a wide range of gaskets currently available in the market. These products can also be classified in numerous ways. For instance, they can be divided according to the materials used to make them, their applications as well as functions. Typically a company specializing in designing and creating gaskets & packing products create them in a number of different models. A gasket often comes in the form of a part that is cut from a flexible material that generally sits between two or more other surfaces. The gaskets are often manufactured from different types of soft materials like rubber. They are used for a wide range of functions such as sealing pipes for preventing leakage of liquids. The gaskets have also got certain other types of common applications like mounting and anti vibration.
The gaskets generally inherit the properties associated with the materials used for manufacturing them. The gasket materials are chosen based on their resistance to some specific chemicals like acids or the properties of being able to withstand extreme pressures or temperatures. Some of the most common materials used for gaskets include rubber, cork and non-asbestos items. Rubber is a type of soft gasket material. Different types of elastomers like neoprene, EPDM, nitrile and natural rubber can be used to create them. Rubber gaskets are often used in different types of applications like pipe gaskets, manways and heat exchangers. The non-asbestos gaskets on the other hand are manufactured from compressed fiber that is combined with elastomer binding. They can be used for various applications involving acid, oil, steam, and water. The cork gaskets are made from natural cork that is combined with the elastomer bindings for ensuring high compression and flexibility. The cork gaskets are used widely in applications that involve fuel, oil and solvents.
Gaskets are frequently used for sealing off a unit against the ingress or leak of liquids. Rubber in the liquid seals must be specified to liquids that are being used in a process. There are certain types of rubber that offer enhanced resistance to chemicals like viton. Nitrile on the other hand is well suited for industries working with fuels, oils and solvents. The gaskets can also be used to function as environmental seals, mountings and anti vibration pads. Such uses make gaskets indispensable in various industrial settings.
