Governs design practices for chemical plants, petroleum refineries, and pharmaceutical facilities.

) ordered from the manufacturer must account for structural degradation over time and fabrication tolerances: The schedule number defines the wall thickness for

Once $t$ is calculated, the engineer selects a standard (e.g., Sch 40, Sch 80, Sch 160). The schedule number defines the wall thickness for a given nominal pipe size (NPS). A higher schedule number means a thicker wall, which translates to a higher pressure rating. The mechanical properties and dimensions for these schedules are standardized in ASME B36.10M for carbon steel pipes and ASME B36.19M for stainless steel.
