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

Automatically build standard products in SOLIDWORKS with TSFP.

Bezšvové za tepla tvárnené oceľové rúry na všeobecné použitie podľa ukrajinskej národnej normy, so stenou do 75 mm, nie konštrukčné duté profily ako ДСТУ EN 10219-2 a ДСТУ EN 10210-2. Rúry sa vyrábajú z uhlíkových a legovaných ocelí. Tabuľka 1 normy zahŕňa vonkajšie priemery od 32 do 530 mm s hrúbkami steny od 2,5 do 75 mm; rozmer sa objednáva podľa vonkajšieho priemeru a hrúbky steny a hmotnosť 1 m sa počíta podľa vzorca normy pri hustote ocele 7,85 g/cm³. Platí od 1. januára 2021 namiesto ГОСТ 8731-74, ГОСТ 8732-78 a ГОСТ 9567-75. Rúry objednávané podľa vnútorného priemeru alebo v iných rozmeroch sa dohodnú s výrobcom a do tabuľky rozmerov nepatria.
