FAQs

What information does the pipe schedule chart provide?

It provides steel pipe dimensional data by NPS (inches) and outside diameter (O.D. in mm), plus schedule-based values across multiple wall thickness categories such as STD, XS, and 80/100/120/140/160/XXS.

How are the pipe sizes organized in the table?

Rows are organized by NPS values (e.g., 1/8, 1/4, 1/2, 1, 2, etc.), while columns show O.D. in millimeters and schedule-specific thickness-related entries (10, 20, 30, STD, 40, 60, XS, 80, 100, 120, 140, 160, XXS).

Which schedule columns can be used to compare different pipe thickness levels?

The chart includes schedule columns such as 10, 20, 30, STD, 40, 60, XS, 80, 100, 120, 140, 160, and XXS, allowing comparison of corresponding values for the same NPS.
