ДСТУ 8938
ДСТУ 8938 - Seamless hot-deformed steel pipes - Technical specification
Automatically build standard products in SOLIDWORKS with TSFP.
Σωλήνες χωρίς ραφή, θερμής διαμόρφωσης, γενικής χρήσης κατά εθνικό πρότυπο της Ουκρανίας, με τοίχωμα έως 75 mm, και όχι κοίλες δομικές διατομές όπως τα ДСТУ EN 10219-2 και ДСТУ EN 10210-2. Οι σωλήνες κατασκευάζονται από ανθρακούχους και κραματωμένους χάλυβες. Ο πίνακας 1 του προτύπου καλύπτει εξωτερικές διαμέτρους από 32 έως 530 mm με πάχη τοιχώματος από 2,5 έως 75 mm· ένα μέγεθος παραγγέλλεται με την εξωτερική διάμετρο και το πάχος τοιχώματος, και η μάζα ανά μέτρο προκύπτει από τον τύπο του προτύπου με πυκνότητα χάλυβα 7,85 g/cm³. Σε ισχύ από την 1η Ιανουαρίου 2021 σε αντικατάσταση των ГОСТ 8731-74, ГОСТ 8732-78 και ГОСТ 9567-75. Σωλήνες που παραγγέλλονται με εσωτερική διάμετρο ή σε άλλα μεγέθη συμφωνούνται με τον παραγωγό και δεν ανήκουν στον πίνακα μεγεθών.
