Faiga o le gaosiga o paipa u'amea e leai ni so'oga. E tusa ai ma lona faiga o gaosiga, e vaevaeina paipa u'amea e leai ni so'oga i paipa u'amea e vela vevela, paipa u'amea e leai ni so'oga e toso malulu, paipa u'amea e leai ni so'oga ua tu'i ma fa'aloaloa, ma paipa u'amea e leai ni so'oga ua fa'aoso fa'alava. O faiga muamua e lua e fa'aaogaina e gaosia ai paipa u'amea e leai ni so'oga lautele, o lona lautele e masani ona 8-406, ma le mafiafia o le puipui e masani ona 2-25; o faiga mulimuli e lua e fa'aaogaina e gaosia ai paipa u'amea e leai ni so'oga tetele ma mafiafia o le puipui, o lona lautele e masani ona 406-1800, ma le mafiafia o le puipui e 20mm-220mm. E tusa ai ma lona fa'aaogaina, e mafai ona vaevaeina i nipaipa u'amea e leai ni so'oga mo fausaga, paipa u'amea e leai ni so'oga mo vai, paipa u'amea e leai ni so'oga mo paila, mapaipa u'amea e leai ni so'oga mo paipa suau'u.
