Fa'agasologa o le gaosiga o paipa uamea. E tusa ai ma lona faagasologa o le gaosiga, ua vaevaeina paipa uʻamea solo i vevela-taai seamless paipa uʻamea, malulu-tosi seamless paipa uʻamea, tuʻi ma faaloaloa seamless paipa, ma vertically extruded seamless paipa uʻamea. O faiga muamua e lua o loʻo faʻaaogaina e gaosia ai paipa uʻamea faʻafefete lautele-caliber, o le lautele e masani lava 8-406, ma o le mafiafia o le puipui e masani lava 2-25; o faiga mulimuli e lua o loʻo faʻaaogaina e gaosia ai paipa uʻamea faʻapipiʻi le tele-caliber mafiafia puipui, o le lautele e masani lava 406-1800, ma le mafiafia o le puipui o le 20mm-220mm. E tusa ai ma lona faʻaaogaina, e mafai ona vaevaeina ipaipa u'amea lamolemole mo fausaga, paipa u'amea lamolemole mo vai, paipa u'amea lamolemole mo boilers, mapaipa u'amea lamolemole mo paipa suauu.
