Fa'agasologa o gaosiga
Seamless paipa paipa gaosiga faagasologa ua vaevaeina i vevela-taai ma malulu seamless paipa.
1. Fa'agasologa o gaosiga o paipa u'amea su'esu'e vevela fa'a'a'ai: fa'alava fa'ameamea → fa'avevela → fa'aoso → tolu-lo'a/fa'alava & ta'avale faifaipea → de-paipa → sizing → fa'alili → fa'asa'o → su'ega hydraulic → fa'ailoga → paipa u'amea seamless fa'atasi ai ma le leverage aafiaga ua iloa.
2. Fa'agasologa o gaosiga o le malulu tosoina paipa u'amea: fa'alava avanoa → fa'avevela → fa'aoso → fa'aulutala → annealing → pickling → oiling → tele ata malulu → tu'u avanoa → vevela → fa'asa'o → su'ega hydraulic → fa'ailoga → teuina.
Talosaga
1. Fausiaina: o le paipa i lalo, o le eleele, ma le felauaiga o vai vevela.
2. Fa'ainisinia fa'ainisinia, fa'aofuofu lima, fa'agaioia vaega o masini, ma isi.
3. Fa'aeletise: Tu'uina atu o kesi, paipa vai eletise eletise
4. Anti-static tubes mo laau malosi matagi, ma isi.
