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. .
