PIPE SCHEDULE DIMENSIONS CHART

HOW TO USE THIS CHART

Find your nominal pipe size, then select the appropriate schedule designation based on your project requirements.

Use the pipe schedule chart below to look up nominal pipe size (NPS), outside diameter (OD), wall thickness, and estimated weight per foot for Schedule 40 (STD), 80 (XH), 160, and other standard schedules based on ANSI/ASME B36.10 dimensions. Pipe schedule determines wall thickness, inside diameter, and pressure rating. Use this chart to quickly look up the dimensions for your pipe size and schedule.
