Pajpijiet tal-azzar li ma jsaddadx huma maqsuma f'pajpijiet tal-azzar tal-karbonju ordinarji, pajpijiet tal-azzar strutturali tal-karbonju ta 'kwalità għolja, pajpijiet strutturali tal-liga, pajpijiet tal-azzar illigat, pajpijiet tal-azzar li jġorru, pajpijiet tal-azzar li ma jissaddadx, u pajpijiet komposti bimetalliċi, pajpijiet indurati u miksija biex jiffrankaw metalli prezzjużi u jiltaqgħu rekwiżiti speċjali..
Skont il-metodu ta 'produzzjoni, huwa maqsum f'żewġ kategoriji: pajpijiet mingħajr saldatura u pajpijiet iwweldjati.Pajpijiet ta 'l-azzar mingħajr saldatura jistgħu jinqasmu f'pajpijiet irrumblati bis-sħana, pajpijiet irrumblati fil-kesħa, pajpijiet miġbudin fil-kesħa u pajpijiet estrużi.Il-pajpijiet miġbudin fil-kesħa u rrumblati fil-kesħa huma l-ipproċessar sekondarju tal-pajpijiet tal-azzar;Pajpijiet iwweldjati huma maqsuma f'pajpijiet iwweldjati b'ħjata dritta u pajpijiet iwweldjati spirali.
Skont il-forma tas-sezzjoni trasversali, tista 'tinqasam f'tubu tond u tubu b'forma speċjali.Tubi b'forma speċjali jinkludu tubi rettangolari, tubi tad-djamanti, tubi ellittiċi, tubi eżagonali, tubi ottagonali, u diversi tubi asimmetriċi.
