Rauemi paipa maitai kore hononga: Ko te paipa maitai kore hononga he mea hanga ki te kongakonga maitai, ki te ngongo totoka rānei mā te poka ki roto i te ngongo taratara, kātahi ka hurihia ki te wera, ka hurihia ki te matao, ka kumea ki te matao rānei. Ko te tikanga he mea hanga te rauemi ki te maitai waro kounga teitei pērā i te 10,20, 30, 35,45, te maitai hanganga iti-koranu pērā i te16Mn, 5MnV, maitai koranu rānei pērā i te 40Cr, 30CrMnSi, 45Mn2, 40MnB mā te huri wera, te huri matao rānei. Ko ngā paipa tui kore i hangaia ki te maitai waro iti pērā i te 10 me te 20, e whakamahia whānuitia ana mō ngā paipa tuku wai.
I te nuinga o te wā, ka wehea te tukanga whakaputa paipa maitai tuimotu ki ngā momo e rua: te tukanga tāmi matao me te tukanga hurihuri wera. E whai ake nei he tirohanga whānui mō te rere o te tukanga o ngā paipa maitai tuimotu tāmi matao me ngā paipa maitai tuimotu hurihuri wera:
Te tukanga paipa maitai kore-whakakorikori matao (pōtaka matao): te whakarite me te tirotiro i te pire ngongo → te whakamahana pire ngongo → te whakapūpū → te hurihuri ngongo → te whakamahana anō i te paipa maitai → te rahi (te whakaiti) te diameter → te maimoatanga wera → te whakatikatika ngongo kua oti → te whakaoti → te tirotiro (kore-whakangaro, ā-tinana me te matū, te tirotiro pae) → te rokiroki
Me huri tuatahi ngā paipa maitai kore-whakakorikori matao ki te huri tonu i ngā porowhita, ā, me whakamātautau ine i muri i te whakaputanga. Mēnā kāore he pakaru urupare i te mata, me tapahi te paipa porowhita e te mīhini tapahi, ka tapahia kia rite ki ngā porowhita, tata ki te kotahi mita te roa. Kātahi ka uru ki te tukanga whakamahana. Me whakapūkara te whakamahana ki te wai waikawa. I te wā e whakamahana ana, kia tūpato mēnā he nui ngā mirumiru i te mata. Mēnā he nui ngā mirumiru, ko te tikanga kāore te kounga o te paipa maitai e tutuki i ngā paerewa e rite ana.
Te tukanga paipa maitai kore-whakakorikori wera (whakaputaina): te pire ngongo porowhita → te whakamahana → te poka → te hurihuri whakarara toru-pukapuka, te hurihuri tonu, te whakaputanga rānei → te tango ngongo → te rahi (te whakaiti rānei) te diameter → te whakamatao → te ngongo pire → te whakatikatika → te whakamātautau pēhanga wai (te kimi hapa rānei) → te tohu → te rokiroki
E ai ki te ingoa, he nui te pāmahana o te takahurihuri wera mō te wahi takahurihuri, nō reira he iti te ātete ki te whakarerekētanga, ā, he nui te nui o te whakarerekētanga ka taea te whakatutuki. Ko te āhua tuku o ngā paipa maitai kore-whakataka wera ka takahurihurihia ki te wera me te whakamahana i mua i te tukunga. Ka tirotirohia te ngongo totoka, ka tangohia ngā hapa o te mata, ka tapahia kia rite ki te roa e hiahiatia ana, ka whakatakotoria ki waenganui o te mata pito o te ngongo kua pokaia, kātahi ka tukuna ki te oumu whakamahana hei whakamahana, ka pokaia ki te pokaia. I a ia e pokaia ana, ka huri haere tonu, ka neke whakamua. I raro i te mahi a ngā roera me te pane, ka puta he kōhao i roto i te ngongo, e kiia nei ko te ngongo taratara. I muri i te tangohanga o te ngongo, ka tukuna ki te mīhini takahurihuri ngongo aunoa hei takahurihuri anō, kātahi ka whakatikatikahia te matotoru o te pakitara e te mīhini whakataurite, ā, ka whakatauhia te diameter e te mīhini ine kia tutuki ai ngā whakaritenga. I muri i te maimoatanga takahurihuri wera, me whakahaere he whakamātautau pokaia. Mena he nui rawa te diameter pokaia, me whakatika me te whakatika, ā, i te mutunga ka tohua he tapanga ka rongoa.
Te whakataurite i te tukanga tātuhi matao me te tukanga hurihuri wera: He uaua ake te tukanga hurihuri matao i te tukanga hurihuri wera, engari he pai ake te kounga o te mata, te āhua, me te tika o ngā āhuatanga o ngā pereti maitai hurihuri-matao i ērā o ngā pereti hurihuri-wera, ā, ka angiangi ake te matotoru o te hua.
Rahi: Ko te whānui o waho o te paipa tuitui wera-hurihia he nui ake i te 32mm, ā, ko te matotoru o te pakitara he 2.5-200mm. Ko te whānui o waho o te paipa maitai tuitui-hurihia matao ka taea te tae ki te 6mm, ko te matotoru o te pakitara ka taea te tae ki te 0.25mm, ko te whānui o waho o te paipa pakitara-angiangi ka taea te tae ki te 5mm, ā, ko te matotoru o te pakitara he iti iho i te 0.25mm (ahakoa he iti iho i te 0.2mm), ā, he teitei ake te tika o te āhua o te hurihuri matao i te hurihuri wera.
Āhua: Ahakoa he iti ake te matotoru o te pakitara o te paipa maitai kore-whakakorikori matao i te paipa maitai kore-whakakorikori wera, he mārama ake te mata i te paipa maitai kore-whakakorikori wera matotoru, kāore te mata i te tino taratara, ā, kāore i te nui rawa ngā kohao o te whānui.
Tūnga tuku: Ka tukuna ngā paipa rino hurihuri wera i te āhua hurihuri wera, i te āhua tukatuka wera rānei, ā, ka tukuna ngā paipa rino hurihuri matao i te āhua tukatuka wera.
