(1) paipa paiherea i te pereti maitai fehokotaki'anga ki te putorino a tawhio noa, wehea ki te auau teitei ātete paiherea putorino (ERW paihere paipa), tui tika paipa arc fehokotaki'anga paipa (LSAW), tōrino paiherea putorino.Electrical engineering ki "SC", ka taea te whakamahi i te mea ka taea hoki te whakamahi paipa hau wai hei paipa miro, he ahua matotoru.

(2) Pipeline pipe, hoki e mohiotia ana he paipa waea, he ahua kikokore, e tohuhia ana e "T", ka taea anake te whakamahi mo te miro.

(3) Ko te ngongo ERW he "tiketike te kaha o te atete ki te ngongo maitai", a he rereke te tikanga whakahiato noa, ko te raina weld mai i te papanga turanga o te tinana o te whitiki maitai kua rewa, he pai ake te kaha miihini i te welding.ERW whanui. mo te weriweri atete, he pai nga ahuatanga o te mahi whakangao nui, te utu iti, te penapena rawa me te ngawari o te miihini, na reira ka whakamahia nuitia i roto i te rererangi, te aerospace, te kaha, te hikohiko, te miihini, te umanga marama me etahi atu waahanga ahumahi, ko tetahi o nga ngā tukanga fehokotaki'anga nui.
