Paipa maitai kua whakakikoruatia ki te uku konumoheHe paipa hiato mahi-teitei tēnei i hangaia mā te herea pūmau i te uku alumina parakore-teitei ki te pakitara o roto o te paipa maitai. Ko te paparanga uku he 95% te alumina (Al₂O₃), me te pakeke Rockwell neke atu i te HRA85 me te pakeke Mohs tata ki te 9, ko te tuarua anake ki te taimana. Ka whakakotahi tēnei hanganga i te ātete kakahu teitei o te uku alumina me te kaha me te pakari o te maitai, kia pai ai mō ngā āhuatanga whakakoi kino. Ka tutuki ngā hoahoa paipa ki ngā paerewa hangarau, ā, ka taea te whakarite i te roa, te whānui, me ngā tikanga hononga.
Ko ngā tukanga hanga matua ko te tikanga here piri me te tikanga whakarewa. Ka whakamahia e te tikanga whakarewa he piripiri kaha-teitei, ātete-wera hei whakapiri pūmau i ngā taera uku alumina kua oti te hanga ki te pakitara maitai o roto, he mea tika mō ngā taiao pāmahana-waenga ki te iti (te nuinga o te wā ≤150°C). Ka whakamahia e te tikanga whakarewa he tikanga whakarewa motuhake hei hono tika i ngā taera uku kua pokaia ki te pakitara maitai o roto, ka hangaia he hononga whakarewa miihini i waenga i te uku me te paipa turanga, e āhei ai te ātete ki ngā pāmahana teitei ake (te nuinga o te wā ≤350°C) me te kaha ake o te pānga. Ka whakarite ngā tukanga e rua i tētahi arai uku maeneene, kāore he pakaru me te here pono ki te paipa turanga.
Ko ngā painga matua o tēnei paipa kei roto i tōna ātete tino pai ki te kakahu me te roa o te ora ratonga. I raro i ngā āhuatanga mahi ōrite, ko tōna ātete kakahu neke atu i te 20 ngā wā i ngā paipa maitai waro noa, ka whakaiti nui i te auau whakakapinga me ngā utu tiaki. Hei tāpiri, he ātete pai ki te waikura me te mata maeneene o roto, e whakaiti ana i te ātete ki te kohikohi rauemi me te kawe. He whānuitia te whakamahinga i roto i ngā ahumahi pēnei i te whakaputa hiko, te mahi whakarewa, te keri, me te tukatuka matū mō te kawe paura, te whakahaere paru, me ngā pūnaha kawe hau, e whai hua ana ki te whakatika i te kakahu nui o ngā paipa.
