3/4 1,050 For stainless steel pipes thru 12-inch, schedule numbers from

Schedule 5S to schedule 80S are used as published in ANSI/ASME 36.19M Stainless Steel Pipe.

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

1/4 0.540

3/8 0.675

1/2 0.840

Identification

For all pipe sizes the outside diameter (O.D.) remains relatively constant. The variations in wall thickness affects only the inside diameter (I.D.). Steel Stainless Steel Schedule No. 1/8 0.405

To distinguish different weights of pipe, it is common to use the Schedule terminology from ANSI/ASME B36.10 Welded and Seamless Wrought Steel Pipe:
