ДСТУ 8938 - Seamless hot-deformed steel pipes - Technical specification

Seamless hot-deformed steel tubes for general purposes, made of carbon and alloy steels. Table 1 of the standard lists outside diameters from 32 to 530 mm with wall thicknesses from 2.5 to 75 mm; a size is ordered by its outside diameter and wall thickness, and the mass per metre follows the formula of the standard at a steel density of 7.85 g/cm³. In force since 1 January 2021 in place of ГОСТ 8731-74, ГОСТ 8732-78 and ГОСТ 9567-75. Tubes ordered by inside diameter or in other sizes are agreed with the producer and are not part of the size table.

ДСТУ EN 10219-2 - Cold formed welded structural hollow sections of non-alloy and fine grain steels - Part 2: Tolerances, dimensions and sectional properties

Cold formed welded structural hollow sections of circular shape, formed from steel strip at room temperature and welded along the seam. Covers outside diameters up to 2 500 mm with wall thickness up to 40 mm; the size table of the standard runs from 21.3 to 1 219 mm with walls from 2 to 30 mm. A circular section has no corner radius and no major or minor axis, so the area, the mass, the second moment of area, the section moduli and the torsional constants follow from the outside diameter and the wall thickness alone. Identical adoption of EN 10219-2:2019. The square and rectangular shapes of the same standard are listed in the square/rectangular tube subgroup.
