Oct 12, 2026

ANSI Pipe Schedule SI-Units (metric) table for industrial pipe material supply. Provides nominal pipe sizes in inches with corresponding outer diameters in millimeters, wall thickness options, and weight expressed in kg/m, plus volume per meter (m3/m). Includes schedule grades such as STD, XS, XXS and other thickness categories, with computed values for different pipe sizes. Labeled for austenitic steel basis and intended for shipping and procurement use.

FAQs

What information does the ANSI Pipe Schedule table provide?

It lists nominal pipe size in inches and corresponding outer diameter (OD in mm), wall thickness values, weight (kg/m), and volume per meter (m3/m) across different schedules.

Which measurement system is used in the schedule?

The schedule is presented in SI units (metric), as indicated by “SI-UNITS (METRIC)” in the document.

What does “Based on austenitic steel” indicate?

It specifies that the tabulated schedule values are based on austenitic steel assumptions for the pipe material.
