Finding the best sealing materials for Food Grade Applications

You will find rubber seals across various industries, providing an important element and operating as a vital fixing across a wide range of different applications and equipment.  However, these FDA gaskets must follow strict, set guidelines, in terms of their material...

The Evolution of Gasket Solutions

When we talk about gaskets and the history of a gasket, we must start at the very beginning.  What is a gasket?  Ultimately, a gasket is a manufactured seal that is used to fill the gap/space between two or more surfaces.  Gaskets are typically manufactured by cutting...

How to preserve your gasket

Gaskets and seals don’t last forever. However, they are designed, or they should be, last for a considerable period.  In this sense, it is vital to look at ways to preserve your gaskets in order to avoid any application downtime.  Downtime that involves additional...

Important Design Features of Rubber Sealings

When it comes to designing the perfect rubber sealing, there are a few design features to bear in mind to help achieve the optimum solution.  In this post, we explore these rubber sealing features further and provide information on the benefits and best uses for these...

Optimal Squeeze for an O Ring to be effective

A doughnut-shaped seal that is primarily used to stop liquids and air from escaping or getting into specific spaces is the function and role of an O Ring.  Also known as a mechanical gasket, O rings are designed to fit between a groove and a compression during the...

High-temperatures and O Rings, what you need to know

Fluctuations in temperature and indeed heat is a significant factor across many applications that make use of o rings.  However, what is well known is how destructive heat can be when it comes to compound deterioration.  You are making choosing the ideal o ring...

How to restore your damaged rubber seals

Under the right circumstances and having the right tools to hand, you can restore rubber gasket seals and have them working as good as new in no time.  Rubber gasket seals provide a seal between two separate mechanisms, providing airtight seals to keep liquids and...

The importance of backup rings to O rings

Backup rings are ultimately used to help stop o ring migration, and they achieve this in both static and dynamic fluid power applications as the pressure cycles occur, preventing the extrusion of an o ring in the gap.  Ultimately a backup ring is a rigid ring that...

Gasket manufacturing process explained

Designing seals for the food industry

There’s a number of factors to take into consideration when designing seals for the food industry. That’s because seals used within this sector need to work exceptionally hard in all food processing environments where hygiene and health and safety are of the utmost...

Properties of Spiral Wound Gasket

Ring Type JointWound gaskets are one of the most common industrial parts and a have a wide range of application. It is a mechanical seal that is used to avoid leakages by filling space between two or more mating surfaces. There is a variety of gaskets available in the market today. Out of these types, spiral wound gaskets are considered suitable for diverse applications. They are supposed to be most reliable and allow lower clamping forces compared to another kind of gaskets.   

What are Spiral Wound Gaskets?

These gaskets have a mix of metallic and filler material in alternating layers. The layer of metal provides structural support while filler material acts as a sealing element. The gasket consists of stainless steel or carbon-rich metal that is wound outwards in a circular spiral. The wounding of filler material is done in the same way but from opposite side. The spiral winding is done to a V-shaped metal strip. The outer metal layer holds the gasket centrally while controlling compression. The inner filler layer increases the resilience and axial rigidity of the gasket.  

Properties of Special Wound Gasket

Special wound gaskets have applications across different industries like shipbuilding, pharmaceutical, nuclear stations, food processing, petrochemical and more. Here are few must know properties of special wound gaskets –  

  • They provide sealing under very heavy operating commercial and industrial conditions.  
  • Their construction works very well as a sealant. They restrict the flow of water, gas or air.  
  • These gaskets enhance the efficiency of normal operations and safety.  
  • They can be used with acids, gases, alkaline, steam, liquids, oil and other organic solvents and mediums.  
  • The materials used for the construction of these baskets are chosen on their ability to compress and recover under load.  
  • They can be used with acids, gases, alkaline, steam, liquids, oil and other organic solvents and mediums.   
  • Their exclusive properties make them ideal for use in high pressure, high-temperature applications.  
  • They can also be used for low-temperature applications in chemical plants, storage solutions, cryogenic facilities and more.   
  • These gaskets can be used for sealing flanges, pressure vessels, heat vessels, boilers, valves and compressors, tube covers, handheld covers and more.  
  • They offer strong stress compensation and reliable and stable sealing performance even under conditions that cause pressure fluctuations.  
  • These offer sealability even when the surfaces are bent or corroded slightly.  
  • They offer optimum performance in fluctuating/ low bolt loads.  
  • These gaskets offer improved pressure rating, long-lasting performance and elastic recovery.  
  • These are precision engineered solutions that provide resistance to any toxic or corrosive element.  
  • These gaskets are produced in a different combination of materials and styles to suit various industrial and commercial applications.   

Most commonly used special wound gaskets are made from steel with a filling material of Asbestos and Graphite. You can easily find an application of spiral wound gasket around different industries and processes. There is a spiral wound gasket available for each kind of application. So, research about basic wound gaskets to figure out the right one for your industrial and commercial requirement.
