How do Spiral Wound Gaskets perform in high pressure sealing applications?

Spiral Wound Gaskets (metal spiral wound gaskets) have performance in high-pressure sealing applications, mainly in the following aspects:
Sealing performance:
Spiral Wound Gaskets are currently a widely used sealing gasket. Its structure consists of V-shaped or W-shaped thin steel strips alternately wound with various fillers. This structure gives the gasket sealing performance. It can adapt to the surface accuracy of various flange sealing surfaces. By changing the material combination of the gasket, it can solve the problem of chemical corrosion of the gasket by various media.
Pressure resistance:
The gasket can withstand high temperature, high pressure and adapt to ultra-low temperature or vacuum conditions. For example, graphite-wound Spiral Wound Gaskets can withstand operating pressures up to 100kg/cm² over a temperature range of -150°C to 450°C, while asbestos-wound gaskets have a temperature range of -200°C to 550°C Inside, it can withstand operating pressures up to 250Kg/cm². These properties make it a significant advantage in high-pressure sealing applications.
material selection:
The inner and outer rings of Spiral Wound Gaskets are usually made of metal materials such as carbon steel (such as 304), while the fillers include soft materials such as graphite, asbestos, and polytetrafluoroethylene. The selection of these materials makes the gasket have corrosion resistance and resilience, and can maintain stable sealing performance in various media and environments.
Structural design:
In order to strengthen the main body and ensure accurate positioning, the spiral wound gasket is equipped with a metal inner reinforcing ring and an outer positioning ring. These designs allow the gasket to maintain a stable shape and position when subjected to pressure, ensuring a long-lasting seal.
Installation and maintenance:
Installation of Spiral Wound Gaskets is relatively simple and requires no special tools or equipment. At the same time, due to its durability and stability, the gasket is not easily damaged or aged during long-term use, reducing the frequency of maintenance and replacement.
To sum up, Spiral Wound Gaskets have sealing performance, pressure resistance, material selection, structural design, installation and maintenance in high-pressure sealing applications. These characteristics make it widely used in aerospace, chemical, energy and other industries, making it an important choice in the field of high-pressure sealing.
