Ka taea te hanga i ngā rauemi mata mō te hanga maitai hurihuri-wera, maitai hurihuri-matao rānei mā roto i tētahi tukanga.
Rino Wera-WhārikiI roto i te tukanga whakaputa, ka whakamahanahia tuatahitia te maitai hurihuri-wera i ngā pāmahana teitei, kia taea ai te hurihuri i te maitai ki te āhua kirihou, kia māmā ai te whakarerekē i te āhua me te rahi o te maitai. I te mutunga o te tukanga hurihuri wera, ka whakapūmautia te rauemi, ka whakapēhia hoki.
Rino Huri-MataoKa hurihia anō te maitai hurihuri-matao i muri i te whakamataotanga o te rauemi kia tutuki ai te rahi me te āhua e hiahiatia ana. Ko te tikanga ka mahia tēnei tukanga i te pāmahana rūma, ā, ka hua ake he maitai he kounga mata pai ake, he tika ake hoki ngā ine.
Me hanga ngā ngongo e tewhakarewa ātete-hiko (ERW)tukanga
Ko te paipa ERW he tukanga hanga whakarewa mā te takai i tētahi mea whakarewa ki roto i tētahi rango, me te whakamahi i te ātete me te pēhanga puta noa i tōna roa.
Me tutuki te maitai ki ngā whakaritenga hanganga matū kua tohua i te Ripanga 1, i te Ripanga 2 rānei.

E whakaaetia ana te whakamahi i te paekōtui hei tikanga tāpiri mō te tautuhi.
Me pania ngā paipa ki te hinu i mua i te tukunga hei ārai i te waikura.
Me kī te ota ka tukuna ngā paipa me te korehinu aukati waikura, ka noho tonu te kiriata o ngā hinu e pā ana ki te hanga ki te mata.
Ka taea e ia te ārai i te tauhohenga o te mata o te paipa ki te makuku me te hāora i te rangi, ā, ka karohia te waikura me te pirau.
Ahakoa ka taea e te hinu whakahinuhinu taketake, te kiriata hinu rānei te whakarato i tētahi taumata tiaki rangitahi, mō ngā tono e hiahia ana ki tētahi taumata tiaki teitei ake, me whiriwhiri te maimoatanga tiaki waikura e tika ana i runga i te kaupapa takitahi.
Hei tauira, mō ngā paipa tanumia, he3PEka taea te whakamahi i te paninga (polyethylene-paparanga-toru) hei whakarato i te tiakitanga waikura mō te wā roa; mō ngā paipa wai, heFBEka taea te pani i te paninga (paura epoxy honohono-hanumi), i te wāwhakakoiHe kōwhiringa whai hua pea ngā maimoatanga i roto i ngā taiao e hiahiatia ana te tiaki mai i te waikura konutea.
Mā te whakamahi i ēnei hangarau motuhake hei ārai i te waikura, ka taea te whakaroa ake i te roa o te ora o te paipa, me te pupuri tonu i tōna mahi.
