Which change in process or steam service fittings is measured in degrees?

The measurement in degrees for process or steam service fittings is specifically associated with directional change fittings. These fittings are designed to alter the path of the piping system, typically in connection with the flow of steam or other fluids. The degree measurement indicates the angle of change in direction, which is critical for ensuring proper flow dynamics and pressure management within the system. Common angles for directional changes include 90 degrees, 45 degrees, and other specified angles that directly impact how the steam or fluids travel through the pipes. Understanding these angles is essential for effective piping design and installation, allowing steamfitters to create systems that function properly without causing excessive pressure drops or turbulence.
