Spiral wound gaskets are designed to eliminate leaks, pressures, and escaping air and water. These are used in a wide variety of applications, from chemical processing plants to research laboratories. They are also used in a number of piping systems.The most common material for the windings of spiral wound gaskets is stainless steel. However, other filler materials are available for special application requirements. Materials such as flexible graphite are a popular choice for oil refineries. This type of filler has been tested in critical applications around the world and offers better performance than asbestos fillers.
An inner ring is another important part of the design of a spiral wound gasket. It reduces turbulence and increases axial rigidity. Besides, it protects the sealing element and prevents it from buckling inside the flange.Another major factor that affects the performance of a spiral wound gasket is the density of the winding. If the winding is too loose, the seal will not hold properly. Ideally, the seal should be made with thinner strips of soft filler.
Depending on the operating conditions, the type of filler used may also be considered. For example, a graphite-based filler is usually resistant to corrosion, but some processes require the filler to be coated with corrosion inhibitors.A spiral wound gasket is a very strong and durable design. They can seal elevated temperatures as high as 550°F and are suitable for a wide range of pressures. In addition, they are easily installed and can be customized to meet the needs of the customer.
