How To Select The Perfect Spiral Wound Gaskets?

Spiral wound gaskets play a significant role in our everyday lives as they are widely used in daily appliances and engines that we use every day. They are used in many applications of power generation, petroleum, chemical, shipbuilding, metallurgy, and many other industries. These gaskets are used in multiple valves, pumps, pipes, heat exchangers, and other equipment. It is crucial to understand the usage of high-quality spiral wound gaskets and their selection in order to eliminate leaks, drops, and pressures, while enhancing safety and normal operations. Gaskets are mainly used to prevent escape of air, gas, and water in commercial and industrial situations. Because they are highly important for the proper functioning of a variety of machineries, it is important to select the right gasket for your application. This blog will help you know how you must choose your spiral wound gaskets, and what things you must keep in mind while doing so.

Environmental factors

Gasket failures are caused due to uneven pressures, unaddressed temperatures, stress, and loss of torque on securing bolts. This is why it is advised that you first understand the environment in which your gasket will be placed so that you can select the perfect gasket. These environmental factors include fluid pressure, temperature, and maximum stress applied, to name a few. Once you have all this information, you can move ahead to make a good choice regarding the material, shape, and size of your gasket.

Chemical resistance

The corrosive property of the fluid contained plays a very significant role for selecting the material of your gasket. Therefore, it is very important to understand the level of chemical resistance your gasket will require. For example, rubber is resistant to oil, but cannot be used with oxidizing fluids. Some materials can be used in acidic conditions while others can be used in alkaline settings. This is why it is very important to have all these details in order to correctly select the right gasket.

Material

There are four main types of materials used to manufacture gaskets. Let us first learn about these materials, their properties, and benefits.

·        Metallics – These materials are those made from a single metal, or a combination of metallic materials in various shapes and sizes. Metallics are great for high pressure and high temperature applications.

·        Non-metallics – These materials can tolerate huge amount of pressure, and can be easily compressed under low bolt load. They are used in pipe flanges, compressor valves, and heat exchangers.

·        Elastomerics – These materials are elastic, extensible, incompressible, and impermeable. They can be deformed, but can never be reduced in volume. This material category includes rubber, neoprene, CP, EP, and IIR.

·        Fibrous – These materials could be of many different types, each with unique properties. This category includes carbon fiber, glass, cork, mica, Teflon, and MMMF.

Performance testing

It is absolutely vital to test a gasket accurately for performance to make sure that it meets the required parameters for your application. You can use tests like hot compression test, creep relaxation test, etc. to make sure that the gasket will be able to withstand the temperature, pressure, compression, and chemical resistance.

Because you may not be a professional in the field, you will need the assistance of a trained designer and engineer along the way. Be armed with all your specific information and work with professional engineers to correctly design or select the best gasket for your specific application.
