Uploaded by Ben

ANSI/ASME pipe dimensions chart listing nominal pipe sizes with corresponding nominal diameters (DN), schedule designations, outside diameters in millimeters, wall thickness in millimeters, and weight per meter in kilograms. The tables provide values across multiple pipe size ranges and schedules (including variants like STD, XS, XXS) for practical selection and comparison in piping and mechanical design. Useful for quick dimensional lookup when specifying pipe material and estimating mass.

FAQs

What information does the ANSI/ASME pipe dimensions chart provide?

It provides, for each nominal pipe size and schedule, the nominal diameter (DN), outside diameter (mm), wall thickness (mm), and weight per meter (kg).

How are pipe schedules represented in the chart?

Schedules are listed alongside each pipe size, including values such as 5, 10, 20/30/40, 80, 100/120/140/160, and variants like STD, XS, and XXS where shown.

How can the chart help when specifying piping?

It enables quick comparison of dimensional and mass characteristics for different pipe sizes and schedules, supporting specification of appropriate outside diameter and wall thickness while estimating weight per meter.
