Piping components like flanges are classified by pressure ratings (Classes 150, 300, 600, 900, 1500, 2500). The maximum allowable working pressure of a flange decreases as the operating temperature increases. Engineers must use ASME B16.5 rating tables to cross-reference the material group, design temperature, and pressure class. 4.

The code defines five fluid service categories, each with different design, examination, and testing requirements:

hm=K⋅(v2/2g)h sub m equals cap K center dot open paren v squared / 2 g close paren Total systemic head loss ( hLh sub cap L ) equals the sum of all major and minor losses: 3. Pipe Sizing Methodology and Economic Optimization Try again later

When routing high-velocity gases or steam, density changes significantly with pressure drops. Designers must ensure the fluid velocity does not approach the speed of sound, which triggers (

): Fluid moves in smooth, parallel layers. Viscous forces dominate. Critical/Transition Zone (

If downstream pressure stays below vapor pressure, the fluid remains a mix of liquid and vapor, causing high velocity and erosion.
