Spiral wound gaskets are semi-metallic gaskets that comprise of both metallic and non-metallic materials, wherein one material is wound around the other; thus bringing it the name ‘spiral wound’. The metal offers strength and resiliency, while the non-metallic material provides sealability and conformability. The design of a spiral wound gasket is in the form of a metallic ring with flexible filler material in the center, so that the sealing property is maintained, no matter what the situation. The material selection for windings depends upon various factors like corrosion, operating temperature, fluid concentration, etc. The most commonly used metal for spiral wound gaskets is Stainless Steel; and the filler materials used for spiral wound gaskets are generally Graphite and Asbestos. These gaskets are designed specifically for high temperature and high pressure applications. You obviously want to get in touch with the most reliable spiral wound gasket manufacturers in India, when looking to buy a gasket. So, for any kind of metallic, non-metallic, and semi-metallic gaskets, and specially the best spiral wound gaskets, you can approach Trim Engineering Services to get the best-in-class products. Now, let us look at the various properties and applications of spiral wound gaskets.

Properties

As mentioned above, spiral wound gaskets are made up of layers of metal and filler materials. This construction is highly beneficial as a sealant when intense and fast loading effects are applied to a flange. The materials used in such gaskets are carefully chosen, and those that are known for their ability to compress and recover under load are only selected. When fastening bolts are tightened around a toughened flange, the layered metal and filler strips bind together to create a tenacious seal. Other exclusive properties of spiral wound gaskets include long lasting performance, elastic recovery, improved pressure rating, and better performance in low/fluctuating bolt loads. With all these amazing properties, spiral wound gaskets are used to eliminate leaks, drops, and pressures, while enhancing safety and normal operations. They also prevent escape of air, gas, and water in commercial and industrial situations.

Applications

Although these spiral wound gaskets are used in applications where high temperature and high pressure are seen, but they can also be used in low temperature applications like in cryogenic facilities, chemical plants, and research laboratories, where low temperature storage solutions and subsidiary equipment coolant mechanisms are seen. Other applications where spiral wound gaskets are used are in extremely toxic applications like chemical processing plants and petrochemical refineries. You can see spiral wound gaskets placed in pumps, pipes, valves, heat exchangers, and other equipment that are used in a wide variety of industries like chemical, petroleum, power generation, metallurgy, and shipbuilding. This is because the materials used in building these gaskets is carefully chosen to withstand high temperatures, high pressures, and corrosion effectively.

So now, you can be sure that spiral wound gaskets are the best that you can use for almost any and every kind of application. However, when you choose your gaskets, make sure you do so with Trim Engineering Services, the leading spiral wound gasket manufacturers in India.
