Paipa LSAW(Longitudinal Submerged Arc-Welding Pipe), ka kiia hokiSAWL paipa. Kei te tango i te pereti rino hei rauemi mata, ka whakarewahia e te miihini whakakikorua, katahi ka mahia nga taha-rua o te pewa kua rukuhia. Ma tenei mahi ka whiwhi te paipa rino LSAW i te ngawari, te pakari o te weld, te riterite, te kirihou me te hiri nui.
He nui ake te awhe diameter paipa LSAW i te ERW, mai i te 406mm ki te 2020mm. He pai nga mahi i runga i te pehanga teitei, me te iti o te wera o te waikura.
Paipa SSAW(Spiral Submerged Arc-Welding Pipe), ka kiia hokipaipa HSAW(Helical SAW), he rite te ahua o te raina ki te helix. Kei te whakamahi te reira i te taua hangarau fehokotaki'anga o Submerged Arc-Welding ki LSAW paipa. He rereke te paipa SSAW he paiherea torino ki te wahi e paiherea ana te LSAW. Ko te mahi hangahanga kei te huri i te tira maitai, kia whai koki te ahunga hurihuri ki te ahunga o te pokapu putorino, te hanga me te whakapiri, no reira kei roto i te raina torino te tuitui whiri.
Ko te awhe diameter paipa SSAW mai i te 219 mm ki te 2020 mm. Ko te waahanga painga ka taea e tatou te tiki i te diameter rereke o nga paipa SSAW me te rahi o te riipene rino, he whanui te tono mo te riipene rino rawa, me te tui raima. kia karo i te ahotea tuatahi, mahi pai ki te mau i te ahotea.
