Ngā paipa maitai ERWhe mea hanga ki te "ātete" hiko auau iti, auau teitei rānei. He paipa porowhita ēnei i whakarewaina mai i ngā pepa maitai me ngā hononga roa. Ka whakamahia hei kawe i ngā mea hau me ngā mea wai pērā i te hinu me te hau māori, ā, ka taea te whakatutuki i ngā whakaritenga rerekē o te pēhanga teitei me te pēhanga iti. I tēnei wā, he tūranga matua tōna i roto i te ao o ngā paipa kawe waka.
I te wā e whakarewahia ana ngā paipa ERW, ka tukuna te wera ina rere te iahiko mā roto i ngā mata pa o te rohe whakarewa. Ka whakamahanahia e ia ngā taha e rua o te maitai kia taea ai e tetahi taha te hono. I tēnei wā, i raro i te pēhanga hononga, ka rewa ngā taha o te paipa parakore ka puta ngātahi.
I te nuinga o te wāNgā paipa ERWhe 24 inihi (609 mm) te whānui o waho, ka hangaia ngā paipa nunui mā te whakamahi i te SAW.
He maha ngā paipa ka taea te hanga mā te whakamahi i te tikanga 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 māori, ā, ka taea te whakatutuki i ngā whakaritenga pēhanga iti me te pēhanga teitei. I ngā tau tata nei, me te whanaketanga o te hangarau ERW, kua piki haere te maha o ngā paipa maitai ERW e whakamahia ana i roto i ngā mara hinu me te hau, te ahumahi motuka, me ētahi atu.
