Carbon, Alloy and Stainless Steel Pipes - ASME/ANSI B36.10/19

Pipe sizes, inside and outside diameters, wall thickness, schedules, moment of inertia, transverse area, weight of pipe filled with water - U.S. Customary Units

steel pipes

The steel pipe data chart below can be used to find pipe sizes, diameters, wall thickness, working pressures and more The chart is based on ASME/ANSI B 36.10 Welded and Seamless Wrought Steel Pipe and ASME/ANSI B36.19 Stainless Steel Pipe.

Regardless of schedule number, pipes of a particular size all have the same outside diameter (not withstanding manufacturing tolerances). As the schedule number increases, the wall thickness increases, and the actual bore is reduced. For example:

  • A 4 inches (100 mm) Schedule 40 pipe has an outside diameter of 4.500 inches (114.30 mm), a wall thickness of 0.237 inches (6.02 mm), giving a bore of 4.026 inches (102.26 mm)
  • A 4 inches (100 mm) Schedule 80 pipe has an outside diameter of 4.500 inches ( 114.30 mm), a wall thickness of 0.337 inches (8.56 mm), giving a bore of 3.826 inches (97.18 mm)

STD, XS and XXS

To distinguish different weights of pipe, three long standing traditional designations are used:

  • standard wall - STD
  • extra strong wall - XS
  • double extra strong wall - XXS

The last two designations are sometimes referred to as extra heavy wall (XH), and double extra heavy wall (XXH).
