Te tukanga hanga paipa rino kore-tuitui. E ai ki tōna tukanga hanga, ka wehea ngā paipa rino kore-tuitui ki ngā paipa rino kore-tuitui hurihuri-wera, ngā paipa rino kore-tuitui kumea-matao, ngā paipa rino kore-tuitui pokaia me te totoro, me ngā paipa rino kore-tuitui whakaputa poutū. Ko ngā tukanga tuatahi e rua ka whakamahia hei hanga i ngā paipa rino kore-tuitui whānui, ko te whānui ko te 8-406, ā, ko te matotoru o te pakitara ko te 2-25; ko ngā tukanga whakamutunga e rua ka whakamahia hei hanga i ngā paipa rino kore-tuitui pakitara matotoru nui, ko te whānui ko te 406-1800, ā, ko te matotoru o te pakitara ko te 20mm-220mm. E ai ki tōna whakamahinga, ka taea te wehea kingā paipa maitai kore-tuitui mō ngā hanganga, ngā paipa maitai kore-tuitui mō ngā wai, ngā paipa maitai kore-tuitui mō ngā kōhua, mengā paipa maitai tui kore mō ngā paipa hinu.
