Gaskets are used as seals in between the plates of a Heat Exchanger. High-strength, form-shaped rubber gaskets are widely agreed upon as industry standard

Having the right tools for the job is always important, and the same goes for gaskets. Depending on the precise function of your exchangers, and the types of material sluicing through, you’ll want to make sure that the gaskets you purchase will be up to the task for as long as possible. Efficiency can’t take place without quality and when it comes to your Heat Exchanger, thinking about your gaskets is a great place to start.

Structure and Composition

It might seem like a simple piece of rubber when you’re holding it in your hand, but the gaskets that go into your Plate Heat Exchangers are complex organic systems—the result of extensive performance testing and industrial research. A lot of work goes into the creation of gaskets—compositions are designed and calculated on a molecular level which affect everything from the elasticity to the colouring.

Vulcanizing chemicals (like sulfur) allow substances to bind together, creating what’s known as cross-linked polymer. This allows the native rubber polymer to be combined with components that possess the qualities and elements you would associate with rubber gaskets, determining the value and worth of the composition.

Fillers make up the strength of the rubber and give it form and rigidity while providing resistance to tension. Carbon black, a commonly used industrial filler, shares its black pigmentation with the rubber its used in.

Anti-degradants fight against the natural aging of the rubber, working against compounds and atmospheric elements that would deteriorate the material over time.

Manufacturing and Research

Between the hundreds of different polymers and fillers and vulcanizing agents and strengthening components it’s easy to get confused. It’s important to remember that not all gaskets are created equal and that while different brands of gaskets might be comparable in size and shape, their composition might differ in critical ways. Industry leaders like Alfa Laval work year-round in a perpetual cycle of experimenting and testing various components, all in an effort of further improving the performance and productivity of Plate Heat Exchangers. According to the research team at Alfa Laval, the research that goes into narrowing down the best of the best when it comes to rubber material is a lengthy 6 step process:

  1. 4 months of studying previous experiments
  2. The top 10 rubber materials decided to be the most promising are subjected to a variety of physical and chemical tests for, a battery that can sometimes take 5 months
  3. Material observed to be the best are taken from the short list and placed into Plate Heat Exchangers for up to 1 whole year
  4. Feasibility of industrial scale production is considered and evaluated, potentially taking as long as 2 months
  5. The 2 best gasket compounds undergo practical application testing for at least 1 year. This really puts the chosen material to the test, showing researchers how it will fare during day-to-day operation—along with how it will stand up to cleaning and servicing
  6. The best rubber material is approved for mass production! In the case of Alfa Laval, the compound recipe is kept secret and adhered to without modification to ensure the safety and quality of the resulting product

Advantages and Limitations

You only get out what you put in, and the same goes for rubber gaskets. Their chemical composition will determine their lifespan and ability to handle various media. Furthermore, poor quality gaskets (or gaskets that are not proofed for the work) might falter depending on the operating temperature of the Plate Heat Exchanger.

Take EPDM for example, a synthetic polymer. Commonly utilized in industrial processing, EPDM is known for its resistance of corrosive material and its ability to withstand higher temperatures. However, EPDM swells in reaction to oils—not something you want to have happening inside your plate pack! Certain variants of NBR (nitrile rubber) would be a more suitable choice if oil were coming into contact with the gaskets. Understanding the strengths and weaknesses of the wide variety of products available on the market makes all the difference. Investing in premium parts that have been rigorously tested means that you’re getting quality and reliability that you can depend on.

The Right Gasket

Valutech specialists are able to navigate through massive databases with ease to find the optimal gaskets for your units and applications—making sure that the gaskets will function as needed at specific temperatures and pressures. Merely identifying specifications and designations simply isn’t enough, as rubber composition, brand of manufacturer, and future-proofing are all equally as important. The productivity and performance of your Heat Exchangers depend on specificity. Don’t make an “educated guess,” or leave it up to chance. When it comes to your Heat Exchanger gaskets, leave it up to Valutech. We’re more than ready to get you sorted out when it comes down to the particular needs of your equipment. You’ll find a few examples of the different gasket types below, just to give you an idea about how the products can vary:

Genuine Alfa Laval Rubber Gaskets

Genuine Alfa Laval Rubber Gaskets

Viton® supplies two different types of gaskets, FKMT and FKMG. these are generally utilized in high-temperature, steam based applications. Viton gaskets are for use with stainless steel plates up to 180°C (356°F) and with titanium plates up to 100°C (212°F).

NBR gaskets are are ideal for water-to-water applications in non-process related duties such as heat recovery and potable water applications. NBR gaskets can be used in temperatures up to 138°C (280°F).

EPDM gaskets possess a notable resistance to water, steam, salt solutions, acids, and alkalies. They are generally used in water-to-water, high temperature applications.

OTHER TYPES OF GASKETS FOR SPECIFIC APPLICATIONS ARE ALSO AVAILABLE
