Paipa LSAW(Paipa Whakarewa-Āwhata Ruku Roa), e kiia ana hokiPaipa SAWLKa tangohia te pereti maitai hei rauemi mata, ka hangaia mā te mīhini hanga, kātahi ka mahia he whakarewa pewa rua-taha i raro i te wai. Mā tēnei tukanga ka whiwhi te paipa maitai LSAW i te ngāwari pai, te pakari o te whakarewa, te ōrite, te kirihou me te hiri pai.
He nui ake te whānuitanga o te paipa LSAW i te ERW, mai i te 406mm ki te 2020mm. He pai te mahi i runga i te ātete ki te pēhanga teitei, me te ātete ki te waikura i te pāmahana iti.
Paipa SSAW(Paipa Whakarewa Āwhata-Roto-Porowhita), e kiia ana hokiPaipa HSAW(Helical SAW), he rite te āhua o te rārangi whakarewa ki te helix. E whakamahi ana i te hangarau whakarewa ōrite o te Submerged Arc-Welding me te paipa LSAW. He rerekē te paipa SSAW he whakarewa porowhita kei reira te LSAW e whakarewahia ana ki te taha roa. Ko te tukanga hanga he huri i te rīpene maitai, kia koki ai te ahunga hurihuri ki te ahunga o te pokapū o te paipa, ka hangaia me te whakarewa, kia rite te hononga whakarewa ki te rārangi porowhita.
Ko te whānuitanga o te paipa SSAW kei waenga i te 219 mm ki te 2020 mm. Ko te painga, ka taea e tātou te tiki i ngā diameter rerekē o ngā paipa SSAW me te rahi ōrite o te rīpene maitai, he whānui te whakamahinga mō te rauemi mata o te rīpene maitai, ā, me karo te hononga whakarewa i te ahotea tuatahi, he pai te mahi hei pupuri i te ahotea.
