Te Whakakī Hanganga Uku Ātete Wera mō te Whakakī Pourewa
Te Whakakī Hanganga Uku Ātete Wera mō te Whakakī Pourewa
He maha ngā wāhanga tākai o te Tākai Hanganga Uku he rite te hoahoa āhua. He rau kōpikopiko kua whakanohoia ki roto i ngā wāhanga porotaka whakarara e kiia nei ko te tākai pourewa kōpikopiko. He momo tākai tino whai hua ēnei, he maha ngā wā teitei ake te whai huatanga wehewehe i tērā o te tākai korekore. He iti te hekenga pēhanga, he nui ake te ngāwari o te mahi, he iti rawa te pānga whakanui, me te nui rawa o te maimoatanga wai ki te whakataurite ki te tākai pourewa korekore.

● Te kaha nui. Mā te hoahoa hou o te pourewa ka whakaiti i te whānui, mā te whakahou i ngā pourewa tawhito ka nui ake te kaha.
● He tino pai te wehewehe. Nā te mea he nui ake te horahanga mata motuhake ki te whakataurite ki te takai matapōkere.
● He iti te hekenga pēhanga, ka tino whakaiti i te whakapaunga pūngao.
● He ngāwari nui, ā, kāore i te kitea te pānga tauine.
● He pai mō ngā diameter katoa o te pourewa.
● He ātete kaha ki te waikura o te waikawa me te kawakore, inā koa ki te H2S, te waikawa naphthenic me te Cl-.
● Te whakatikatika i te halide waro.
● Te whakatika me te mimiti i ētahi ranunga waikura, e tino whakahaerehia ana i roto i te hekenga pēhanga me te tau pereti ariā.
● Whakamahia ki ētahi pourewa kei roto he nui te nui o te rauemi taiao e whakamahia ana hei mimiti i te waikawa hauota me te waikawa whanariki kukū, tae atu ki te purenga o te hau i roto i ngā tipu matū.
● E mahi ana i raro i te korehau i te pēhanga tino raro o te 100pa.
● Whakamahia hei whakawhiti wera me te tango kohu, hei kawe whakakorikori rānei.
1. Te nui o te uta wai me te kohu, ka taea te hanga i te diameter o te pou kia iti ake mō ngā taputapu hou, ā, ka taea te whakanui ake i te kaha
tino nui mō te whakahounga o te pou o nāianei.
2. He ātete teitei ki te nuinga o ngā waikawa kohuke me ngā waikawa waro me ngā mea e pā ana ki tēnei, ā, he ātete wāhanga ki te kawakore.
3. He pai te whakawhiti papatipu. He nui ake te horahanga mata motuhake i te takai matapōkere.
4. He iti te hekenga pēhanga, he nui te penapena pūngao.
5. He whānui te ōwehenga hurihanga. He ngāwari te whakanui ake.
6. He pai mō ngā rahi katoa o te pou.
