DOM / seamless mechanical round steel tube (ASTM A513): common OD × wall sizes, 3/8 to 12 in OD, + 100 mm sections for the sizes distributors agree on

What OD × wall sizes does DOM (drawn-over-mandrel) steel tube come in, and what is the ID of 1-1/2 × 0.120 DOM? · Standard part · basis: Metals Depot's 117-size DOM (A513 Type 5) table, Alcobra Metals' 1020 DOM list (1-1/4 and 1-1/2 in OD) and Online Metals' A513 list (first 24 sizes read) cross-checked; weights left out

Also called: dom tubing sizes, 1.5 x 0.120 dom id, 1 3/4 dom tube wall, dom tube 1.25 x 0.120, dom 2 inch od tube, a513 type 5 dom dimensions, dom tube 0.095 wall, dom tubing chart od wall id, 1-3/8 dom tubing 0.095, dom tubing for roll cage 1.75, dom 1 inch 0.120 id, dom steel tube 3 inch od, mechanical round tube sizes, dom tubing 4 inch od

Notes

  • DOM (drawn over mandrel) round steel tube is sold by outside diameter and wall in inches; Metals Depot's listing is headed DOM (A513-T5) and Online Metals' list A513. The table is the union of three distributors' lists: 130 OD × wall sizes (117 from Metals Depot, 12 from Alcobra Metals, 24 from Online Metals, which overlap). The last column shows which distributors list each size (MD Metals Depot, AL Alcobra, OM Online Metals). Alcobra and Online Metals print only the first page of their lists in the text read (Alcobra 12 of 62, Online Metals 25 of 139), so a size missing from them is not evidence that it is not made.
  • ID is OD − 2 × wall. Metals Depot prints an ID for every row and Online Metals for its rows; every Metals Depot ID equals OD − 2 × wall to within 0.002 in (checked here; for example 1-1/2 × 0.120 prints 1.260, 2 × 0.250 prints 1.50), and the Online Metals IDs to within 0.005 in (it rounds some to 0.01 in, for example 0.28 for 3/8 × 0.049, which is 0.277). Alcobra's list has no ID. Two Online Metals rows have a conflict between their title and detail (5/8 × 0.065 ID 0.5 vs 0.495, 3/4 × 0.049 wall 0.049 vs 0.154); the first is kept at the wall (0.065, ID derived 0.495), the second is dropped.
  • Weights are not given: Metals Depot's weight column repeats values that cannot both be right (for example 1 in × 0.065 and 1 in × 0.083 both print 0.65 lb/ft, and 5/8 in × 0.156 and × 0.188 both print 0.90), so none of its weights is used.
  • Not on this page: the standard's OD and wall tolerances (ASTM A513 was not read), steel grade (Alcobra's list is 1020; the others do not state the grade here). The Metals Depot page also lists J525 hydraulic and A519 seamless tube, which are not DOM and are left out. Related tables: structural round HSS (aisc-hss-round), steel pipe by NPS (steel-pipe-asme-b36-10m-nps-1-8-to-24).
  • Files: 100 mm hollow sections of the 23 OD × wall sizes that at least two distributors list; the length is Xem's example length.
