What are three basic types of flange face types for gaskets?

The three basic types of flange face types for gaskets include full face, flat ring, and metallic ring. This classification reflects the design and structure of the gaskets used in various piping applications.

A full face gasket covers the entire area of the flange, providing a large sealing surface that helps to prevent leaks and is commonly used in lower-pressure applications. Flat ring gaskets, on the other hand, are shaped to fit the bolt circle and provide a smaller sealing surface than full face gaskets, which can be beneficial in certain configurations where space is limited. Metallic ring gaskets are designed to withstand higher temperatures and pressures; they consist of metal with a softer material for sealing, ideal for applications that involve higher mechanical stresses or aggressive media.

In contrast to this, the other options present combinations of face types that do not accurately encapsulate the standard categories recognized in industry practice. For instance, spiral wound gaskets are a unique type but not classified as a basic flange face type in conjunction with the others. Similarly, while mentioning slip-on and raised face configurations might relate to pipe fittings, they do not represent distinct types of gaskets. Understanding these variations is essential for proper gasket selection in piping systems, ensuring a secure and leak-proof installation, which is paramount
