He momo paipa maitai kore-whakarewa te paipa maitai kore-whakarewa, ā, he nui ake tōna mahi i tērā o te paipa maitai kore-whakarewa noa, nā te mea he nui ake te Cr i roto i tēnei paipa maitai, ā, he pai ake tōna ātete pāmahana teitei, te ātete pāmahana iti me te ātete waikura i ētahi atu paipa maitai kore-whakarewa. Kāore e taea te whakataurite, nō reira he whānuitia te whakamahinga o ngā paipa maitai kore-whakarewa i roto i te hinu, te matū, te hiko, te pōro me ētahi atu ahumahi. He wāhanga tuwhera te paipa maitai kore-whakarewa (Tube Rino Kore-Whakarewa), he rīpene maitai roa kāore he hononga huri noa. He wāhanga tuwhera te paipa maitai, ā, he whānuitia te whakamahinga hei paipa mō te kawe wai, pērā i ngā paipa mō te kawe hinu, hau māori, hau, wai me ētahi rauemi totoka. Ki te whakatauritea ki te maitai totoka pērā i te maitai porowhita, he rite tonu te kaha piko me te torsion o te paipa maitai kore-whakarewa, ā, he mama ake tōna taumaha. He maitai wāhanga ōhanga, ā, he whānuitia te whakamahinga i roto i te hanga wāhanga hanganga me ngā wāhanga mīhini, pērā i te kawe hinu. Mā te hanga wāhanga mowhiti me te paipa maitai kore-whakarewa ka taea te whakapai ake i te tere whakamahinga o ngā rauemi, te whakahaere i te tukanga hanga, te penapena rauemi me te wā tukatuka, pērā i ngā mowhiti whīra hurihuri, ngā huinga tītaha, me ētahi atu, kua whānuitia te whakamahinga i roto i te hanga paipa maitai. He mea nui hoki te paipa rino kore-ira mō ngā momo patu tuku iho, ā, me hanga te oko, te oko, me ētahi atu ki te paipa rino. Hei tāpiri, ina pāngia te wāhanga mowhiti e te pēhanga ā-roto, ā-waho rānei, ka ōrite te kaha. Nō reira, ko te nuinga o ngā paipa rino kore-ira he paipa porowhita.
