Paipa Whakarewahia Porowhita mō ngā Raina Paipa Ahi
Ko te painga matua opaipa porowhita kua whakarewainako te kaha ki te whakaputa paipa maitai o ngā diameter rerekē mai i ngā rīpene o te whānui kotahi. He tino painga tēnei ina hiahiatia he rīpene maitai whaiti hei whakaputa paipa maitai diameter nui. Mā tēnei kaha hanga, ka tukuna e te hua te whānuitanga me te ngāwari ki te whakatutuki i ngā hiahia kanorau o ngā kaupapa me ngā ahumahi rerekē.
Hei tāpiritanga, he tino tika ngā ine o ngā paipa porowhita kua whakarewahia. I te nuinga o te wā, kāore te ātete ki te diameter e neke ake i te 0.12%, kia tika ai, kia ōrite ai hoki te rahi o ia paipa e hangaia ana. He mea nui tēnei taumata o te tika mō ngā tono e tino tika ai te hanganga o ngā ine.

Haunga ngā ine tika, he tino pai te hanganga o te paipa whakarewa porowhita. Nā te mea he iti iho i te 1/2000 te piko, he iti noa te rerekētanga o te paipa mai i tōna āhua tūturu ahakoa ngā pēhanga me ngā kaha o waho e rerekē ana. Mā tēnei ka taea te whakarite i te mahi pono me te whai hua, ā, he pai rawa atu tēnei hua mō ngā mahi nui pēnei i te paipa ahi.
Heoi anō, he iti iho i te 1% te āhua porowhita o te paipa whakarewa porowhita, ā, ka nui ake tōna pakari me tōna pono. He mea nui tēnei whakahaere āhua porowhita mō ngā tono e tika ana kia ōrite ngā kōtaha paipa porowhita mō te rere pai o te wai me te mahi pai o te pūnaha. Ki ngā paipa whakarewa porowhita, kāore e whakaitihia te kounga me te whai huatanga o te tuku wai, te tuku hau rānei.
He mea nui, mā te tukanga hanga paipa whakarewa porowhita ka kore e hiahiatia ngā tukanga whakahāngai me te whakatikatika tuku iho. Ka hua ake tēnei i te penapena wā me te utu nui, ka tino whai hua, ka tino whai hua hoki te hua. Mā te whakakore i ngā mahi hanga tāpiri, ka poto ake ngā wā arahi me te whakaiti i ngā utu whakaputa, ka piki ake te whai huatanga o te kaupapa whānui.
He tino pai te paipa whakarewa porowhita mōngā raina paipa ahihe mea nui ngā whakaritenga haumaru pakari me te mahi pono. Nā tōna tino tika o ngā āhuatanga, tōna hanganga pai, me tōna mana whakahaere porowhita, he mea tino pai mō te kawe i te wai, te pahuka, ētahi atu mea tinei ahi rānei hei tiaki i te ora me ngā taonga.
Hei tāpiritanga, he pai te paipa whakarewa porowhita mō te whānuitanga o ngā mahi kē atu, tae atu ki ngā paipa hinu me te hau, ngā tautoko hanganga me ngā kaupapa hanganga. Nā tōna ngāwari ki te whakamahi me te mahi pai rawa atu, he mea ātaahua tēnei mō te maha o ngā ahumahi e hiahia ana ki ngā paipa maitai kounga teitei.
Hei whakarāpopototanga, he hua tino pai te mahi a te paipa whakarewa porowhita mō te raina paipa ahi, ā, he nui ngā painga. Nā tōna kaha ki te whakaputa paipa maitai o ngā diameter rerekē, ngā ine tika, te hanganga pai rawa atu, me ngā tukanga hanga e penapena ana i te wā, he mea whai hua, he kōwhiringa whai hua hoki. Ahakoa he paipa ahi, he tono kē atu rānei, ka taea e te paipa whakarewa porowhita te whakarato i te kounga me te pono pai hei whakatutuki i ngā hiahia o ngā kaupapa me ngā ahumahi rerekē.
