Fa'agasologa ole gaosiga ole paipa u'amea

1. Ta'avale vevela (paipa u'amea fa'apipi'i fa'alaua'itele): pili fa'alava lapotopoto → fa'avevela → tu'ia → ta'avale koluse tolu-lo'a, ta'avale faifaipea po'o le fa'aosoina → aveese paipa → sizing (po'o le fa'aitiitiga) → fa'amalieina → Fa'asa'o → su'esu'ega fa'alelei (po'o le iloa o mea sese) → fa'ailoga → fale teu oloa.

O mea mata mo le taʻavale paipa paipa o le paipa paipa lapotopoto, O paipa paipa lapotopoto e tipiina e se masini tipi i totonu o se paʻu ma le umi e tusa ma le 1 mita ma auina atu i le ogaumu mo le faʻamafanafanaina e ala i se fusipaʻu. O le piliti e fafaga i totonu o le ogaumu ma faʻavevela i le vevela e tusa ma le 1200 tikeri Celsius. O le suauu o le hydrogen poʻo le acetylene. O le pulea o le vevela i totonu o le ogaumu o se mataupu taua. A uma ona alu ese le paipa lapotopoto mai le ogaumu, e tatau ona tuia i se masini tu'i mamafa. E masani lava, o le masini tu'i masani o le tapered roller piercing machine. O lenei ituaiga masini tui e maualuga le gaosiga o le gaosiga, lelei le lelei o oloa, faʻalauteleina le lautele o le perforation, ma e mafai ona ofuina ituaiga uʻamea eseese. A mae'a ona tu'ia, e fa'asolo fa'asolosolo solo le pepa fa'a'au'au lapotopoto, fa'aauau pea ona ta'avale po'o fa'ate'a e ta'i tolu. A uma ona oomi, aveese le paipa ma fa'avasega.
