Pipe Schedule Dimensions Chart
The Pipe Schedule (SCH) Chart is a standardized reference for the wall thickness and internal dimensions of industrial piping. Tied directly to the Nominal Pipe Size (NPS), the schedule number indicates the pipe's pressure-carrying capacity, where higher schedules mean thicker walls for more demanding service.
Engineers and fabricators use it to ensure correct fluid flow, structural integrity, and safety compliance across piping systems.
