Flange Faces

As you start to consider purchasing flanges or gaskets, you’ll see a variety of terms used that you may not have come across before. Flange faces are the surface area that will receive the gasket, allowing them to come together to create a seal when put under...

Octagonal Ring Type Joints

A ring-type joint is a metallic ring that is machined to sit between two mating surfaces, where it will be compressed to provide a high-quality and reliable seal. Ring-type joints are vital components in various applications across multiple industry sectors,...

Blind Flange vs Blank Flange

Small pieces of mechanical equipment flanges continually play a vital role across numerous industries and applications. In essence, we use flanges to connect pipes to each other, with flanges also found in valves and specific application fittings too. Due to the...

Types of Flanges

Businesses in a variety of industries rely on flanges to join pipes or components together or to keep equipment secured to a surface. When it comes to choosing the best types of flange for your processes, you’ll want to take the time to research the different options...

Threaded Flange

Threaded flanges are probably the most recognisable of all flanges due to their screw thread design that is used to connect it to the pipe. Threaded flanges, also known as screwed flanges (for obvious reasons), require a male and female thread to create a connection...

Slip On Flange

A slip-on flange can also be known as a hubbed flange, which, as the name suggests, has a hub with a very low profile. Why is this important? Because this type of ring type joint gasket has an internal diameter larger than the connecting pipe, allowing you to slide it...

Weld Neck Flange

Also known as tapered hub flanges or high hub flanges, weld neck flanges are a specific type of gasket with a protruding ridge and long neck used to connect pipework and provide you with a high-quality seal. Weld neck flanges, in particular, are a popular choice when...

Nitrile vs Viton® – What is the Difference?

As you start to make a decision about what type of O-rings to purchase for your business, you might wonder what material is the most suitable for your unique needs. Every business operation has different requirements for their O-rings, such as the temperature,...

Aflas vs Viton

When it comes to choosing O ring suppliers in the UK, you’ll find that there are a wide range of materials on offer for you to choose from. Many people find that the options can seem quite overwhelming, with some materials having similar properties but offering...

EPDM Gasket

Both the automotive and construction industries have started to use EPDM gaskets more frequently in recent times. This rubber material is UV light resistant and has many fantastic properties that make this part highly effective for a wide range of processes. Keep...

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. .
