Fa'agasologa o le Gausia o Paipa Uila Fa'apa'u Fa'apa'u-arc:

LSAW paipafa'aaogaina tekinolosi u'u arc fa'afefeteina, fa'aoga uelo fa'atumu, fa'afefe o mea'ai puipuia o lo'o tanumia arc.

O le LSAW o le fa'apu'upu'u fa'a-Peretania o le fa'asu'u arc uelo sa'o paipa u'amea su'isu'i.O le faagasologa o le gaosiga o le arc fa'afefeteina uelo sa'o paipa u'amea e aofia ai le JCOE faiga tekinolosi, coil fausia fa'aluulu arc tekinolosi uelo ma UOE faiga tekinolosi.

Ole fa'agasologa ole gaosiga ole Longitudinal Submerged-arc Welded(LSAW) Pipe e fa'apea:

Fa'ata'ita'iga o ipu eletise → vili pito → mua'i punou → fa'atupu → mua'i uelo → uelo i totonu → uelo i fafo → su'esu'ega o le Ultrasonic → su'esu'ega X-ray → Fa'alautele → su'ega fa'asuavai →l.Chamfering → Su'esu'ega o le Ultrasonic → Su'esu'ega X-ray → su'esu'ega vaega fa'amaneta ile pito fa'agaau.
