Ngā painga o te paipa porowhita whakarewa:
(1) Ka taea te whakaputa i ngā diameter rerekē o ngā paipa rino porowhita mā te koiri whānui kotahi, inā koa ka taea te whakaputa i ngā paipa rino diameter nui mā te koiri rino whaiti.
(2) I raro i te āhua pēhanga ōrite, he iti ake te ahotea o te hononga whakarewa porowhita i te hononga whakarewa tika, arā, 75% ~ 90% o te ahotea o te paipa whakarewa hononga whakarewa tika, nō reira ka taea e ia te tu atu i te pēhanga nui. Ki te whakatauritea ki te paipa whakarewa tika me te diameter o waho ōrite, ka taea te whakaiti i te matotoru o te pakitara o te paipa whakarewa porowhita mā te 10% ~ 25% i raro i te pēhanga ōrite.
(3) He tika te ine. I te nuinga o te wā, kāore te ātete ki te diameter e neke ake i te 0.12%, ā, he iti iho te porowhita i te 1%. Kāore e taea te wareware i ngā tukanga rahi me te whakatikatika.
(4) Ka taea te whakaputa tonu. I roto i te ariā, ka taea e ia te whakaputa i ngā paipa maitai mutunga kore me te iti o te ngaronga tapahi o te upoko me te hiku, ā, ka taea te whakapai ake i te tere whakamahinga whakarewa mā te 6% ~ 8%.
(5) Ki te whakatauritea ki te paipa whakapiripiri tuitui tika, he ngāwari te mahi, ā, he watea te whakarerekētanga me te whakatikatika i ngā momo.
(6) He mama te taumaha o ngā taputapu, ā, he iti ake te haumitanga tuatahi. Ka taea te hanga hei waeine nekeneke momo wakatō hei hanga paipa whakarewa tika ki te papa hanga e whakatakotoria ana ngā paipa.
Ko ngā ngoikoretanga o ngā paipa whakarewa porowhita: nā te whakamahinga o te maitai rīpene hurihuri hei rauemi mata, he piko marama te āhua, ā, kei roto i te rohe taha maitai rīpene pīngore te pūwāhi whakarewa, nō reira he uaua ki te whakarite i te pū whakarewa, ā, ka pā ki te kounga whakarewa. Nō reira, me whakarite he taputapu aroturuki whakarewa me te tirotiro kounga matatini.
