Ka hangaia ngā paipa maitai ERW mā te "ātete" auau iti, auau teitei rānei. He paipa porowhita ēnei e whakarewahia ana mai i ngā pereti maitai me ngā whakarewa roa. Ka whakamahia hei kawe i ngā mea wai-kohu pērā i te hinu me te hau māori, ā, ka taea te whakatutuki i ngā whakaritenga pēhanga teitei me te iti. I tēnei wā, he tūranga matua tōna i roto i te ao o ngā paipa kawe waka.
I te wā e whakarewahia ana te ngongo ERW, ka puta te wera ina rere te iahiko hiko mā roto i ngā mata pa o te wāhi kua whakarewahia. Ka whakamahanahia ngā taha e rua o te maitai ki te wāhi e taea ai e tetahi taha te hono. I taua wā anō, i raro i te pēhanga whakakotahi, ka rewa ngā taha o te ngongo papatahi, ka pēhia ngātahi.
Ko te whānui mōrahi o ngā paipa ERW he 24” (609mm), mō ngā rahi nui ake ka hangaia te paipa ki te SAW.
He maha ngā paipa ka taea te hanga mā te tukanga ERW. Kei raro nei ka whakarārangihia ngā paerewa tino noa mō te mahi paipa.

Te whakamahinga me te whakamahinga o te paipa maitai ERW: Ka whakamahia te paipa maitai ERW hei kawe i ngā mea hau me ngā mea wai pērā i te hinu me te hau, ā, ka taea te whakatutuki i ngā whakaritenga o te pēhanga iti me te pēhanga teitei. I ngā tau tata nei, me te whanaketanga o te hangarau ERW, kua piki haere te whakamahinga o ngā paipa maitai ERW i roto i ngā mara hinu me te hau, te ahumahi motuka me ētahi atu mara.
