1. Whakataki poto o te paipa hanganga

Ko te paipa tuitui mō te hanganga (GB/T8162-2008) e whakamahia ana mō te hanganga whānui me te hanganga ā-pūkaha o te paipa tuitui. Kua wehea te ngongo maitai tuitui ki ngā momo whakamahinga rerekē.

Ko te paipa tuitui kowiri tira mō te hanganga (GB/T14975-2002) he paipa tuitui wera-hurihia (whakaputaina, whakawhanuitia) me te kumea matao (hurihia) i hangaia ki te kowiri tira e whakamahia ana i roto i te matū, te hinu, te kakahu, te hauora, te kai, te mīhini me ētahi atu ahumahi, ngā paipa ātete-waikura me ngā wāhanga me ngā wae hanganga.

Ko te GB/T8162-2008 (paipa tui kore mō te hanganga) e whakamahia ana mō te hanganga whānui me te hanganga mīhini. Ko ōna rauemi matua (waitohu): maitai waro 20, maitai 45, Q235, maitai koranu Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo me ētahi atu.

Paipa maitai kore-tuitui

Nā te rerekētanga o te tukanga hanga, e rua ngā momo o te ngongo maitai kore hononga kua hurihia wera (whakaputaina) me te ngongo maitai kore hononga kua kumea matao (hurihia). E rua ngā momo o te paipa kumea matao (hurihia) ki te paipa porowhita me te paipa āhua motuhake.

A. He tirohanga whānui ki te rere o te tukanga

Te hurihuri wera (ngoi maitai kore hononga i whakaputahia): te pire ngongo porowhita → te whakamahana → te poka → te hurihuri whakawhiti-toru-pōro, te hurihuri tonu, te whakaputanga rānei → te tango i te ngongo → te rahi (te whakaiti rānei) → te whakamatao → te ngongo pātea → te whakatikatika → te whakamātautau pēhanga wai (te kimi hapa rānei) → te tohu → te rokiroki.

Te tuhi makariri (te hurihuri) i te ngongo maitai kore-tuitui: te porowhita o te ngongo porowhita → te whakamahana → te poka → te pane → te whakamahana → te whakamātao → te whakamātao → te hinu (te whakakikorua parahi) → te tuhi makariri maha-haere (te hurihuri makariri) → te ngongo pātea → te maimoatanga wera → te whakatikatika → te whakamātautau pēhanga wai (te kimi hapa) → te tohu → te rokiroki.
