Tukanga Hangarau
Tuke tui: ko te tuke he taputapu e whakamahia ana i te hurihanga o te paipa.I roto i nga taputapu paipa katoa e whakamahia ana i roto i te punaha paipa, ko te waahanga te nui rawa atu, tata ki te 80%.I te nuinga o te waa, ka tohua nga tikanga hanga rereke mo nga tuke he rereke nga taonga me te matotoru pakitara.Ko nga tikanga hanga noa o te tuke tuitui i roto i nga kaihanga ko te pana wera, te hiri, te tangohanga, aha atu.
1. Te pana wera hanga
Ko te mahi whakawera wera, whakawhänui me te whakapiko i te karekau pätea ki runga i te mate i raro i te pana o te mihini pana ma te whakamahi i te mihini pana tuke motuhake, te mate matua me te taputapu whakamahana.Ko te ahuatanga rereke o te tuke pana wera ko te whakatau i te diameter pire e ai ki te ture kia noho tonu te rōrahi o te mea whakarewa i mua i muri mai i te huringa kirihou.He iti iho te diameter pire i whakamahia i te diameter tuke.Ko te tukanga deformation o te pire e whakahaeretia ana i roto i te mate matua ki te rere te whakarewa kōpeke i te pewa o roto, me te utu ki etahi atu wahi thinned e tika ana ki te roha diameter, kia rite ki te whiwhi i te tuke ki te matotoru pakitara ōrite.
Ko te tukanga hanga o te tuke pana wera he ahua ataahua, he rite te matotoru o te pakitara me te mahi tonu, he pai mo te hanga papatipu.Na reira, kua riro te reira i te tikanga hanga matua o te waro maitai me te koranu maitai tuke, a ka whakamahia hoki i roto i te hanga o etahi whakaritenga o te kowiri tira tuke.
Ko nga tikanga whakawera o te mahi hanga ko te auau reo, te whakawera induction auau teitei ranei (ka taea e te mowhiti whakamahana te porowhita maha, te porowhita kotahi ranei), te whakamahana mura me te whakamahana oumu reverberatory.Ko te tikanga whakamahana ka whakawhirinaki ki nga whakaritenga o nga hua i hangaia me nga tikanga kaha.
2. Te hanga hiri
3. Waehere pereti Waenga
Whakamahia te pereti reo hei hanga i te haurua o te wahanga tuke ki te perehi, katahi ka wea nga wahanga e rua.Ka whakamahia tenei tukanga mo nga tuke kei runga ake i te DN700.
Ko etahi atu tikanga hanga
I tua atu i nga tikanga hanga noa e toru i runga ake nei, ko te hanga i te tuke karekau he tango i te tukanga hanga o te tango i te ngongo kia kore ki te mate o waho ka hanga i te poroporo i roto i te ngongo para.Heoi, he tino uaua tenei tukanga, he raruraru ki te whakahaere, a, ko te kounga o te hanga kaore i te pai ki nga tikanga o runga ake nei, no reira he uaua te whakamahi.
