EN 10220 Tube: round · Products: 2065 EN 10220 - Seamless and welded steel tubes - Dimensions and masses per unit length Seamless and welded plain-end steel tubes in three outside-diameter series, including heavy walls up to 100 mm. EN 10220:2002 specifies outside diameters 10.2–2540 mm and wall thicknesses 0.5–100 mm. Mass per unit length follows the formula and rounding rules of clause 5.
ISO 10799-2 Tube: round · Products: 92 ISO 10799-2:2011 - Cold-formed welded circular structural hollow sections - Dimensions and sectional properties Cold-formed welded circular structural hollow sections to ISO 10799-2:2011. The standard specifies nominal dimensions and sectional properties, with circular-section properties defined in Annex A.2.
ISO 4200 Tube: round · Products: 182 ISO 4200 - Plain end steel tubes, welded and seamless - General tables of dimensions and masses per unit length Plain-end welded and seamless steel tubes for general use, with preferred wall thicknesses defined by outside diameter. ISO 4200:1991 specifies dimensions and mass per unit length.
ДСТУ 8938 Tube: round · Products: 1513 ДСТУ 8938 - Seamless hot-deformed steel pipes - Technical specification Seamless hot-deformed general purpose tubes of a Ukrainian national standard, with walls up to 75 mm, not structural hollow sections like ДСТУ EN 10219-2 and ДСТУ EN 10210-2. The tubes are 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 10210-2 Tube: round · Products: 229 ДСТУ EN 10210-2 - Hot finished steel structural hollow sections - Part 2: Tolerances, dimensions and sectional properties Hot finished circular structural hollow sections, seamless or welded: unlike the cold formed sections of ДСТУ EN 10219-2 the tube is formed hot, or formed cold and heat treated afterwards, so the steel has the properties of a hot rolled product, and unlike the general purpose seamless tubes of ДСТУ 8938 it is a structural section with its own size table and sectional properties for design. The standard covers outside diameters up to 2 500 mm with wall thickness up to 120 mm; the size table runs from 21.3 to 1 219 mm with walls from 2.3 to 60 mm. A circular section has no corner radius and no second axis, so the sectional properties follow from the outside diameter and the wall thickness alone, by the same formulae as ДСТУ EN 10219-2. Identical adoption of EN 10210-2:2019.
ДСТУ EN 10219-2 Tube: round · Products: 221 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 hollow sections of circular shape, formed from steel strip at room temperature, unlike the hot finished ДСТУ EN 10210-2 and the seamless ДСТУ 8938. 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.
