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.
