O le paipa uamea ERW o lo'o gaosia e ala i le maualalo o taimi po'o le maualuga o le tete'e "tetee" .O latou o tubes lapotopoto uelo mai ipu u'amea ma welds longitudinal.It e fa'aaogaina e felauaiga ausa-suava mea e pei o le suauu ma le kasa masani, ma e mafai ona ausia tulaga manaomia maualuga ma maualalo o le mamafa.
I le taimi o le faʻapipiʻiina o le ERW tube, e faʻatupuina le vevela pe a tafe le eletise i luga o le faʻafesoʻotaʻi o le vaega uelo. E faʻamafanafana pito uma e lua o le uamea i le mea e mafai ai e le tasi mata ona fausia se faʻamau.
E masani lava ole paipa ERW e iai le maualuga ole OD ole 24”(609mm), mo lapo'a tetele ole paipa ole a fau ile SAW.
E tele paipa e mafai ona faia e le faiga o le ERW. I lalo ifo matou te lisiina tulaga masani i le paipa.
