He whānuitia te whakamahinga o ngā puranga paipa rino i roto i ngā āhuatanga maha pērā i ngā puranga tautoko me ngā puranga waku. Ina koa ka whakamahia hei puranga tautoko, nā te mea ka taea te pana katoa ki roto i tētahi paparanga tautoko pakeke, ka taea e ia te whakamahi i te pānga tautoko o te kaha wāhanga katoa o te rauemi rino. Ahakoa i roto i te turanga oneone ngohengohe hohonu neke atu i te 30m, ka taea hoki te tuku i te puranga paipa rino ki roto i tētahi paparanga tautoko totoka, ā, ka taea te whakamahi katoa i tōna kaha tautoko. I te nuinga o te wā, ko ngā āhuatanga matua o ngā puranga paipa rino ko:
1. Ka taea te tu atu i te pānga kaha. He pai ake ōna āhuatanga urunga me te urunga nā tōna kaha ki te tu atu i ngā kaha pānga kaha. Mena he paparanga mārō kei roto i te turanga he iti te matotoru, ā, he tau urunga paerewa IV=30, ka taea te haere mā te maeneene. Ka taea te uru atu ki roto i te paparanga tautoko totoka e ai ki ngā whakaritenga hoahoa.
2. Te kaha kawe nui. Nā te mea he kaha te kaha tuku o te maitai hei rauemi turanga mō te puranga paipa maitai, ka taea te whiwhi i te kaha kawe nui mena ka totohu te puranga ki runga i tētahi paparanga tautoko totoka.
3. He ātete whakapae nui, he ātete kaha ki te kaha taha. Nā te mea he pakari te wāhanga o ngā puranga paipa rino, he nui hoki te ātete ki ngā ātete piko, ka taea e rātou te tu atu i ngā kaha whakapae nui. Hei tāpiri, ka taea hoki te whakamahi i ngā paipa matotoru te whānui. Nō reira, ka taea te whakamahi whānui ki ngā poupou, ngā tautoko piriti me ngā pou piriti hei pikau i te kaha taha.
4. He tino ngāwari te hoahoa. Ka taea te whakarerekē i te matotoru o te pakitara o ia paipa kotahi o te puranga paipa maitai kia rite ki te hiahia, ā, ka taea hoki te whiriwhiri i te diameter o waho e tutuki ana i ngā whakaritenga hoahoa e rite ana ki te hiahia.
5. He ngāwari te whakarerekē i te roa o te puranga. Tērā pea ka roa ake, ka poto ake rānei ngā puranga kua oti te whakarite ina he pōkaikaha te paparanga e mahi ana hei paparanga tautoko mō te pito o te puranga. Nā te mea ka taea te whakarewa noa i ngā puranga paipa rino kia rite ki te roa, te tapahi rānei kia rite ki te roa mā te tapahi hau, he ngāwari te whakarerekē i te roa o te puranga, kia maeneene ai te mahi hanga.
6. He haumaru ngā hononga, ā, he pai mō te hanga i ngā mea roa. Nā te mea he ngāwari te hanga hononga whakarewa mō ngā puranga paipa rino, ka honoa ngā wāhanga puranga, ā, he ōrite te kaha o ngā hononga ki te kaha o te rauemi turanga, nō reira ka taea te whakatau i te hohonu o te tāurunga e tutuki ai ngā hiahia.
7. He māmā te hono atu ki te hanganga o runga. Mā te whakarewa i ngā pae rino ki te taha o runga o te puranga, ka taea te hono ngāwari i te puranga paipa rino ki te taha o runga o te taupoki me te raima. Ka taea hoki te whakarewa tika ki te hanganga o runga, kia pai ai te mahi tahi o ngā taha o runga me o raro.
8. He iti rawa te rerenga o te oneone i te wā e whakapūpū ana. Ka taea te pana i ngā puranga paipa maitai ki roto i te whakatuwheratanga, he iti te horahanga whakawhiti o te rerenga o te oneone, ā, he teitei te whai huatanga o te taraiwa. Ko ēnei ōna āhuatanga,
a: He iti te pānga o te whakakorikori ki te turanga uku.
b: Kāore he pānga kino ki ngā whare (hanganga) e tata ana, ā, ka taea te mahi i te hanganga pou tino kaha ki runga i tētahi wāhi iti.
c: He tino pai mō ngā whare teitei, ngā turanga taputapu miihini nui me ngā hanganga tauranga, me ētahi atu, ina whakamahia ngā kawenga nui ki ngā wāhi iti.
d: He māmā te kawe me te whakarārangi. He māmā te puranga paipa maitai, nō reira kāore he take e manukanuka ai ki te pakaru, ā, he ngāwari hoki te kawe me te whakarārangi.
e: Penapenahia ngā utu hangarau, whakapotohia hoki te wā hanga. Nā te mea he maha ngā āhuatanga o runga ake nei kei ngā puranga paipa rino, ki te taea te whakamahi katoa i ēnei āhuatanga i roto i ngā kaupapa tūturu, ka taea te whakapoto i te wā hanga. Ko ngā puranga paipa rino te mea tino pai mō te hanga tere. Nō reira, he nui ngā painga ōhanga whānui, ā, ki te whakatauritea, ka taea te penapena i ngā utu hangarau.
