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

Specialist Sealing Products have been providing high-quality gaskets to customers throughout the UK for many years. We pride ourselves in the range of gaskets we have available, suitable for a variety of applications across a range of industries.  Rubber gaskets are...

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...

Storing your gaskets!

A strange headline for a gasket article, we know.  However, it’s an important area and one, which in this sector is often overlooked.  When we think about most products or items in and around our homes and business, we will recognise that most come with manufacturing...

What is Controlled Density for Spiral Wound Gaskets

Spiral Wound Gasket with Controlled DensityThe controlled density of spiral wound gasket is a term used to ensure optimum filler density across windings. This is required to achieve excellent sealability and consistent compression. With this process, it is possible to obtain optimum filler density. It helps in achieving a long-lasting seal with a minimum compressive load. There are guidelines set for manufacturing spiral wound gaskets to ensure optimum controlled density. The process of precise winding density control is designed to ensure consistent sealing of your most critical fluids and specified seating stress.

With controlled density in a manufacturing process, it is possible to achieve tightness in the seal at lower loads. When gaskets are manufactured with controlled density, they are manufactured to a specific Y factor. AY factor can be anywhere between 5000 psi to 10,000 psi. The Y factor is set to contribute to improved performance during stress cycling. Spiral wound gaskets with controlled density provide many benefits like consistent compressibility. The solutions vary on the composition of metals and filler materials of the spiral wound gasket.

Controlled Density of Spiral Wound Gasket Uses

Several industrial processes require methods to combat the fluctuations of temperature and pressure. To achieve this, spiral wound gasket is just the right element to choose. These wound gaskets are précised engineered solutions used in a variety of industrial and commercial applications. They consist of a centre ring, an inner ring, filler material and metal windings. They are used to seal flanged joints, utility holes, heat exchangers and other high pressure and high-temperature applications. Metallic gaskets have proved superior when typical nonasbestos materials have failed. They are used in condensers, heat exchangers, valves, pumps and compressors.

Benefits of Controlled Density in Spiral Wound Gasket

  • These gaskets have a computerised manufacturing process. This ensures that the filler density is optimum across gasket winding for different compressions.
  • Controlled density ensures that high level of tightness can be achieved in the seal while keeping compressive load to a minimum.
  • ROTT tests and results are done to determine temperature sealing capabilities. It was found that controlled density spiral wound gaskets were able to achieve the same level of tightness in all parameter values while keeping load low.

Spiral wound gaskets are also known as maxiflex or metaflex gaskets. They are composed of a pre-formed winding metallic strip and layers of soft filling material like Asbestos and Graphite filled spiral wound gaskets. This unique composition gives it an ability to work well and recover under fluctuating loads.

Spiral wound gaskets have known to provide optimum performance over a wide range of temperature and media. They work equally efficiently with hydrocarbons, water, oils and chemicals. These gaskets have applications across industries like paper and pulp, power generation, oil and gas, hydrocarbon processing and more. The process of winding ensures consistent sealing of the most critical fluids in industrial applications. Based on their composition, spiral wound gaskets are resistant to fire and other hazards in oxidising environments. Spiral wound gaskets are essential in any application where leakage control is required. Based on your requirement, you can choose a perfect composition of the gasket. .
