Choosing a Gasket? Here Are Some Things to Consider

The role played by gaskets are important in everyday life. They are a fundamental component in most engines. Gaskets can prevent both industrial or commercial water, gas and air from escaping. Gaskets are very important when operating a wide variety of machines too. Spiral wound gaskets  are a perfect example of gaskets that play a big role in many pieces of machinery. Choosing the right gasket is essential when picking the overall design. This article takes a closer look at the critical things to consider when selecting the correct gasket that meets your needs.

Figure out the Right Gasket for Certain Applications

Most gasket failure arises from uneven pressure exerted on the mating surface. Other reasons for failure are lost torque, stress relaxation, and temperature imbalance. In that respect, before you consult an expert on the right gasket for use, you must understand every detail regarding their future use. The factors to consider are temperature, fluid pressure, and any corrosive properties of the fluid.

Choose from the Best Selection

Identify the right environment for your gasket to operate in and choose the best materials to use. Elastomeric is impermeable, elastic material that can easily be deformed without reducing volume. They are made of EP, CP, neoprene, and natural rubber.

Fibrous options contain unique properties such as carbon fiber, glass, cork, or Mica. The soft, non-metallic option is easily compressible under low bolt load. They are used in heat exchanges, pipe flanges, and compressor valve gaskets. Their ability to tolerate abuse is quite high. Also present is a metallic alternative that comes in different sizes.

Level of Chemical Resistance

Before picking any of the materials mentioned above, understand their level of resistance to chemical exposure. Corrosive properties within this fluid influence your choice a great deal. For a start, nitrile rubber has a strong level of resistance to oil but remains uncomfortable for use with oxidizing fuels. Alternatively, PTE works best within the – to 14 pH range after which it is unable to withstand molten alkali metals or fluorine. To some, this might be a little confusing. Hence, it would be important to consider all the facts that fit into specific applications.

Metallic Versus Non-Metallic

This factor focuses on the difference between metallic and non-metallic. The first area brings strength while the other gets easier to mold or shape to your needs. Before we proceed, take time to go over semi-metallic materials. The semi-metallic gaskets consist of non-metallic and metallic materials. Once the two are combined, you get strength and metallic resilience which seals of the non-metallic stuff.

Talk to the Gasket Experts

Testing the performance of your gaskets is crucial in ensuring that they meet the right application parameters. Examples of these tests are the creep relaxation, hot compression, and several others. Your gasket should withstand factors such as pressure, temperature, compression, scalability, and chemical degradation.

Choosing a Manufacturer

If all this is overwhelming, this will take out most of your stress. The manufacturer should take time to match you with the best gasket that meets your project. Do not shy away from asking for guidance from the staff.
