ДСТУ 8938
ДСТУ 8938 - Seamless hot-deformed steel pipes - Technical specification
Automatically build standard products in SOLIDWORKS with TSFP.
Bezšuvju karsti veidotas vispārējas nozīmes caurules pēc Ukrainas nacionālā standarta, ar sieniņām līdz 75 mm, nevis konstrukciju dobie profili kā ДСТУ EN 10219-2 un ДСТУ EN 10210-2. Caurules izgatavo no oglekļa un leģētā tērauda. Standarta 1. tabula aptver ārējos diametrus no 32 līdz 530 mm ar sieniņas biezumu no 2,5 līdz 75 mm; izmēru pasūta pēc ārējā diametra un sieniņas biezuma, bet metra masu aprēķina pēc standarta formulas ar tērauda blīvumu 7,85 g/cm³. Spēkā no 2021. gada 1. janvāra ГОСТ 8731-74, ГОСТ 8732-78 un ГОСТ 9567-75 vietā. Caurules, ko pasūta pēc iekšējā diametra vai citos izmēros, saskaņo ar ražotāju, un tās neietilpst izmēru tabulā.
