You must consider the: Chemical resistance Temperature resistance Flexibility Friction Now, irrespective of the type of material you settle for, a gasket can prevent the escape of air, gas, and water in commercial and industrial applications.

What is a Gasket? Types of Gaskets There are various types of gaskets; however, the most common examples include: Custom made gaskets Flange gaskets used in piping Specific material properties for gaskets Gaskets used in vehicles such as boats, cars, planes, and trains Gaskets to achieve a particular function such as high or low pressure, temperature, or chemical resistance Various Types of Gasket Material Chemicals, fuel, tremendous pressure, and extreme temperature often encompass the gaskets.

The different types of gasket material to choose from include: 1. On the other hand, there must be high tension bolting during the use of metallic gaskets.

Non-metallic Gaskets: Non-metallic gasket material is also known as a soft gasket, and this material can be compressed easily with low tension bolting. The following materials create non-metallic gaskets: Compressed Non-Asbestos Fiber CNAF Teflon Rubber Graphite Aramid fiber Glass fiber On the other hand, non-metallic gaskets have found use cases in low-pressure applications around and class and low temperatures applications.

Teflon or PTFE: Teflon also has excellent chemical resistance, which has made it a reputable sealant in chemical industries. Rubber: Rubber comes with good compression properties, and there are cases where synthetic rubber can withstand extreme weather conditions. Fiberglass: Glass is a combination of metal silicates. It has good strength, temperature resistance, and chemical resistance. Cellulose: This material is suitable for use in low to medium pressure and temperature applications.

Ethylene propylene: It is suitable for use in applications that involve corrosive and hydraulic fluids. Composite Gaskets: Composite gaskets are from a combination of metallic and non-metallic materials.

Full Face: These are gaskets that cover all the flange faces and the gasket material includes bolt holes. RTJ: These are metal ring type joint gaskets. Choosing the Gasket Material Based on the Application Each material has different applications irrespective of whether they are metallic, non-metallic, or composite. Conclusion There are several types of material to choose from when it comes to gaskets, and your ability to select the right gasket can bring about joint integrity.

Blow Molding Industry This industry manufactures blow molding machinery. It is suitable for a wide range of pressure and temperature class. There are three components in the spiral wound gasket. However, sometimes an inner ring is not used. You can see in the image spiral wound gasket with and without inner ring. The inner ring is used to provide additional support to the winding material. The winding is an alternative layer of filler material and winding material.

The filler material is a soft material such as graphite and PTFE and winding material is a thin sheet of metal. Filler material, either graphite or PTFE is layered on this grooved metal ring. It is Costlier than Spiral wound gasket but provides better blowout resistance and easy to handle even in large diameters.

Kammprofile gaskets are used in a wide variety of service fluids and operating pressure-temperatures classes from Class to Class flanges. In Metal Jacketed Gasket, the Soft filler material is enclosed in a thin sheet of a metal jacket. There are different ways to cover filler material as shown in the image. Jacketed gaskets are easily fabricated in a variety of sizes and shapes.

They are used in heat exchangers, shell, channel, and cover flange joints. A leak from the flange joint can be disastrous.

A flange leak results in loss of product and energy. No plant operator wants to leak of toxic or hazardous material that can harm humans and the environment. Enclosures the world over have requirements for access for maintenance. Generally, these enclosures contain control equipment that is essential to the operation of the installation that they are linked to.

A foam rubber door gasket fitted to these enclosures play an important part in keeping the integrity of the enclosure and ensuring the equipment inside is kept in an optimum working environment.

Vibration, as with sound, has frequencies. Anti-vibration pads or flooring are a way of disrupting those frequencies and reducing the amount of energy wasted or damage caused by vibration.

Anti-vibration methods are used in area such as machinery mountings, pipe supports or structural bearings. With technology today involving more digital displays to provide information, equipment manufacturers need to protect the sensitive display units from shock, ingress of dust or other particles that may include liquids.

Electrical switchgear also involves the providing of information via displays and typically can require access panels that need gaskets to ensure integrity of protective ratings. Pipe gaskets otherwise known as flange gaskets are made from wide range of materials such as rubber, non-asbestos and graphite. We hold dedicated tooling for all gasket tables such as:.

A Full Face gasket is one that covers the whole of the flange. It will be easily recognised by the fact that the holes for the bolts to pass through are cut into the gasket material. They sit within the circle of the bolts used to secure the joint and are purely a continuous ring of material. Segmented gaskets are used when the flange is an unusual shape, extremely large or expensive. A segmented gasket is formed by two or more gasket parts being arranged with an overlap, tab, or shaped joint arrangement — so that when it is compressed it provides a continuous seal within the flange joint.

Spiral wound gaskets are made by winding a metal strip, typically stainless steel and a softer filler material such as graphite or PTFE. The materials are wound from opposite sides giving alternating layers of metal and filler, with the filler material acting as the sealant and the metal as the structural strength. These gaskets offer the use of lower clamping forces, but are a relatively expensive method of sealing. Manway gaskets are used for a range of applications such as fuel tanks, boilers and other types of closed vessels.

The gaskets involved are subject to many design requirements such as shape round, oval, ob-round , closing mechanism single stud bolt, several sealing bolts and hinged handles , pressure standard fuel tanks to steam pressure vessels and heat requirements.
