Tips for best o ring maintenance

If o rings are not maintained, leaks can occur, and water and other fluids can enter the appliance or application, and even product in the mix!  If this happens, damage can occur to internal parts and mechanisms, causing deployment failings, potential false readings,...

What you need to know about O Ring Lubricants

Silicone grease and lubricants aren’t just a nice to have for o rings, but they can quite often be a must-have.  However, with so many greases and lubricants to choose from, it can often be a minefield choosing the best ones and the right ones for your o ring and...

O Ring Replacement

Replacing an O Ring in pressure washer wands is probably one of the most common replacements you'll find when working with seals.  Unfortunately, O Rings don't last forever, and over time they do deteriorate, and you will require an O Ring replacement.  It's important...

Reasons behind seal failure and a look into seal replacement

Unfortunately, there are occasions where O-rings, in particular, fail.  The failure of these seals is not simply due to one factor, but various factors that can occur across a range of applications – hence why locating the exact cause of such problems is just that, a...

Gaskets and seals for Aerospace

Gaskets and seals used for aerospace applications and equipment must be of premium quality and to a substantially high standard.  They are used across a range of applications such as radars, antennas, lighting, access panels, electrical conductivity, pressure sealing,...

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...

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. .
