Pipe ea Tšepe ea Khabone e se Nang Seam ea ASTM A106: Tataiso e Felletseng bakeng sa Litšebeliso tsa Mocheso o Phahameng

Liphaephe tsa tšepe ea khabone e se nang mohele tsa ASTM A106li sebelisoa haholo lits'ebetsong tsa indasteri tse nang le mocheso o phahameng le khatello e phahameng. Lipeipi tsena li etselitsoe ho fihlela maemo a ASTM International, li fana ka ts'ebetso e ntle ea mechini, ts'epo e phahameng, le ts'ebeliso e feto-fetohang makaleng a matla, petrochemical le indasteri. Tataiso ena e fana ka kakaretso e felletseng eaLiphaephe tsa ASTM A106, ho kenyeletsoa le mekgahlelo, boholo, thepa ya mechini, le ditshebediso tse tlwaelehileng.
