I roto i ngā mahi whakaputa ahumahi me ngā mahi hangarau maha, ko ngā paipa te wāhanga matua mō te kawe rauemi. Ka pā tika te mahi a ngā paipa ki te whai huatanga o te mahi me te pumau o te pūnaha katoa. I roto i ēnei, ko te ātete ki te kakahu tētahi o ngā tohu matua mō te aromatawai i te kounga o ngā paipa. Ko te putanga mai o te hangarau uku alumina mō ngā arai paipa he otinga pai rawa atu ki te raruraru o te kakahu o ngā paipa, ā, ka tino whakarei ake i te ātete kakahu o ngā paipa.
He maha ngā āhuatanga whakamiharo o ngā uku alumina, he rauemi uku hangarau mahi-teitei. Mai i te tirohanga matū, he tino pumau te matū, ka taea te ātete i te mimiti o ngā momo waikura pēnei i te waikawa, te kawakore, me te tote, me te pupuri i te mahi pumau ahakoa i roto i ngā taiao matū kino. Mō ngā āhuatanga ā-tinana, he tino pakari te uku alumina, tae atu ki te 9 te pakeke Mohs, e whai ake nei i te taimana me ētahi atu rauemi tino-pakari. Mā tēnei āhuatanga pakari teitei ka taea te ātete pai i te kakahu ina horoia e ngā matūriki me ngā paura tere-tere, ā, he iti ake te ngawari ki te karawarawa me te pakarukaru.
Ko te whakatakoto i tētahi arai uku alumina ki roto i te paipa he auahatanga nui i roto i te tikanga tuku iho mō te whakapakari i te ātete ki te kakahu o ngā paipa. Ahakoa ka taea e ngā tikanga tuku iho pēnei i te paninga ātete-kakahu, te whakamahi rānei i ngā arai whakarewa noa te whakapai ake i te ātete ki te kakahu ki tētahi taumata, he maha ngā herenga. Ka ngawari te tihore o ngā arai ātete-kakahu i roto i te wā, ka hua ake he whakahekenga nui o te ātete kakahu; ko ngā arai whakarewa noa, ina pāngia e te pakeketanga nui me te tere o te pānga o ngā rauemi, ka tere te pirau, me te hiahia kia whakakapia pinepine, ka piki ake ngā utu tiaki me te wā kore mahi.
Heoi, he rerekē rawa te arai o roto o te paipa i hangaia ki te uku alumina. Mā tōna hononga kaha ki te rauemi turanga o te paipa ka hanga he paparanga pakari, ātete-kakahu. I roto i ngā mahi whaihua, ahakoa he kawe i ngā rauemi pakeke-nui pērā i te konganuku me te waro, he mahi rānei ki ngā wai kei roto he maha ngā matūriki koi, ka taea e te paipa arai o roto o te uku alumina te whakaatu i te ātete-kakahu tino pai. Hei tauira, i roto i ngā paipa kawe rauemi o ngā tipu whakapai keri, i muri i te whakamahinga o te arai o roto o te uku alumina, kua roa ake te ora o te paipa mai i ngā marama maha ki ngā tau maha, ka whakaitihia te auau o te whakakapinga paipa me te whakaheke i ngā utu whakaputa.
Hei tāpiritanga, he tino maeneene hoki ngā paipa arai roto uku alumina, ka taea te whakaiti i te ātete rere o ngā rauemi i roto i te paipa, te whakaiti i te ngaronga pūngao, me te whakapai ake i te pai o te kawe. I te wa ano, he mama noa iho, ā, kāore e nui rawa te taumahatanga ki te hanganga whānui o te paipa, kia ngāwari ai te tāuta me te tiaki.
Nā te hangarau arai uku alumina mō ngā paipa kua piki ake te kounga o te ātete ki te kakahu o ngā paipa nā ngā āhuatanga pai rawa atu o ngā uku alumina. Ehara i te mea ka whakanui ake i te ātete kakahu o ngā paipa, ka roa ake te ora o te mahi, ka whakaitihia hoki ngā utu tiaki me te wā kore mahi, ā, ka whakapai ake i te pai o te whakaputa.
