Pipe Stress Quick Check — ASME B31.3
Pressure thickness, thermal expansion stress, and sustained stress screening per ASME B31.3. Screening only — not a substitute for a Caesar II run on safety-critical piping.
Code: ASME B31.3 Process Piping. Pressure thickness equation t = PD/[2(SEW + PY)] (§304.1.2). Thermal flexibility minimum cantilever leg: Lmin = √(3EIΔy/SA). This is a screening calculator — for compliance design, use a formal pipe stress analysis package (Caesar II, ROHR2, AutoPIPE).
