ДСТУ 8938
ДСТУ 8938 - Seamless hot-deformed steel pipes - Technical specification
Automatically build standard products in SOLIDWORKS with TSFP.
Țevi de oțel fără sudură deformate la cald de uz general, după un standard național ucrainean, cu pereți până la 75 mm, nu profile tubulare de construcții precum ДСТУ EN 10219-2 și ДСТУ EN 10210-2. Țevile se execută din oțeluri carbon și aliate. Tabelul 1 al standardului cuprinde diametre exterioare de la 32 la 530 mm cu grosimi de perete de la 2,5 la 75 mm; o dimensiune se comandă după diametrul exterior și grosimea peretelui, iar masa pe metru urmează formula standardului la o densitate a oțelului de 7,85 g/cm³. În vigoare de la 1 ianuarie 2021 în locul ГОСТ 8731-74, ГОСТ 8732-78 și ГОСТ 9567-75. Țevile comandate după diametrul interior sau în alte dimensiuni se convin cu producătorul și nu fac parte din tabelul de dimensiuni.
