Download a PDF file (18 pages), which includes a full pipe data of NPS 1/8 through NPS 80, cover dimensions and weight of welded and seamless wrought steel pipe as per code ASME/ANSI B36.10M in both Customary & SI Units: Pipes NPS 1/8 thru NPS 80

Note. ASA was superseded by ANSI.

For all pipe sizing, the higher Schedule number is (in any case) characterized by its higher pipe wall thickness compared with the lower Schedule number. For example, for NPS 32, the Sch. 30 represents a pipe wall thickness of 0.625" (15.88 mm), where the higher Sch. 40 (for the same NPS 32) has a higher thickness of 0.688" (17.48 mm), and so on.

But, with checking Table 2 of ASME B36.10M (and also the table at file this link), we can notice that some standard sizes have not including some Schedules numbers, like as (for example):

NPS 22, 28 & 30: the Sch. 40 is not available or not nominated,

NPS 26: both the Sch. 30 and Sch. 40 are not available or not nominated, and

NPS 32: all Sch. 60, 80, 120, ... etc. are not available or not nominated.

Note. For NPS 1/8 up to NPS 10, the Sch. 40 is identical with Sch. STD.

ASTM A 53 Gr. B and ASTM A106 Fr. B gives thicknesses from sch 20 to sch. 160. As far as I know, sch 30 doesn't exist.
