Huri wera (whakaputa paipa maitai kore): ngongo porowhita → whakawera → ​​kowhatu → → toru-roira hurihuri, hurihuri, tangohanga ranei → wehe → rahi (whakaiti ranei) → whakamatao → ​​whakatikatika whakamatautau waipēhi (orflaw) → tohu → rokiroki.

Ko te ngongo korekore o nga rauemi mata he ngongo porotaka, ka haere nga kukune ngongo ki roto i te miihini tapahi ki te tapahi i te tipu o te tohu tata ki te 1 mita, ka tukuna ma te whakamahana oumu whitiki kawe.Ka whangaia te pire ki roto i te oumu whakamahana, ko te pāmahana he 1200 nga nekehanga Celsius.He wahie mo te hauwai, acetylene ranei.He mea nui te whakahaere i te pāmahana oumu ki te mau i te ngongo hau a tawhio noa, i muri i te tukunga o te pehanga puncher.i te nuinga o te nuinga o nga puncher te tope roera punch tenei punch, teitei production pai, te kounga hua, perforated roha whakawhänui, mau momo o maitai.I muri i te perforation, kua toru-roera ngongo ngongo ripeka okeoke, okeoke ranei extrusion.I muri i te tangohanga atu te rahi o te paipa.Te mira rahi ma te tere tere o te hurihanga o te wiri koeko ki roto i te punch Billet hei hanga paipa maitai.Ko te paipa rino te diameter o roto ka whakatauhia e te roa o te diameter o waho o te drill mira rahi.I muri i te rahinga, te putorino maitai ki te tomo i te pourewa meangiti i te meangiti rehu wai, te putorino maitai i muri i tautauā, he mea tika ki te kia tika.Ka tukuna ma te putorino kawe ma te whakatika i te miihini rapu whakarewa (he whakamatautau hydrostatic ranei) hei whakahaere i tetahi hapa o roto.He paipa rino nga take o roto penei i te kapiti, ka kitea nga mirumiru.Te tirotiro i te kounga paipa maitai engari ma te kowhiringa a-ringa.Pupa maitai o te Tirotiro Kounga, Te Tirotiro, whakamahia te peita rehu ki te nama, te rahi, te puranga whakaputa.Ma te waka taura e iri ana ki te whare putunga.
