WHAT ARE SPIRAL WOUND GASKETS?
The spiral wound gasket was developed in the early 20th century to meet the increasingly demanding conditions encountered in oil refinery operations. This type of gasket is commonly used with flange surface finishes created using Mirage flange facing machines, which is why we decided to put together this simple overview as an introductory guide for the on-site machinist.

Gasket Seating
There are two major factors to be considered with regard to gasket seating. The first is the gasket material itself. The ASME Unfired Pressure Vessel Code Section VIII, Division 1 defines minimum design seating stresses for variety of gasket materials. These design seating stresses range from zero psi for so-called self-sealing gasket types such as low durometer elastomers and O-rings to 26,000 psi to properly seat solid flat metal gaskets. Between these two extremes there are a multitude of materials available to the designer enabling him to make a selection based upon the specific operating conditions under investigation. Table 1 indicated the more popular types of gaskets covered by ASME Unfired Pressure Vessel Code.
