Which type of fitting is characterized by having raised face dimensions?

The type of fitting characterized by having raised face dimensions is a flanged fitting. Flanged fittings have a raised face that provides a more reliable seal when two flanged surfaces are bolted together. This design helps accommodate the gasket used in the connection, ensuring that it is properly compressed and preventing leaks in the piping system.

Flanged fittings are commonly used in a variety of applications, particularly where frequent maintenance and disassembly are needed, as they allow for easy connection and disconnection without having to cut or damage pipes.

The other types of fittings, such as socket weld, orifice, and threaded fittings, do not typically feature raised face dimensions. Socket weld and threaded fittings rely on their respective engagement methods for sealing, while orifice fittings are designed specifically for measuring flow rather than accommodating a raised sealing surface.
