✧ Ngā Āhuatanga o te Pōnati Porowhita Porowhita BS 1873

1. Te whakatuwhera me te kati kore-waku. Mā tēnei mahi ka ea katoa te raruraru e pāngia ana te hiri o ngā takirere tuku iho e te waku i waenga i ngā mata hiri.
2, momo hanganga o runga. Ka taea te tirotiro tika me te whakatika i te takirere kua tāutahia ki te paipa ipurangi, ka taea ai te whakaiti i te wā e tū ai te taputapu me te whakaiti i te utu.
3, hoahoa nohoanga kotahi. Ka whakakorea te raruraru e pāngia ana te reo i roto i te kōhao takirere e te pikinga pēhanga rerekē.
4, hoahoa taipana iti. Ka taea te whakatuwhera me te kati i te kakau takirere me te hoahoa hanganga motuhake mā te kakau ringa iti.
5, hanganga hiri poro. Ka hiritia te takirere e te kaha miihini e whakaratohia ana e te kakau takirere, ā, ka pēhia te poro pōro ki te nohoanga, kia kore ai e pāngia te hiri o te takirere e te huringa o te rerekētanga pēhanga o te paipa, ā, ka whakamanahia te mahi hiri i raro i ngā tikanga mahi rerekē.
6. Hanganga horoi-ā-koe o te mata hiri. Ina piko te pōro mai i te nohoanga, ka rere te wai i roto i te paipa 360° te ōrite i te mata hiri o te pōro, e kore e whakakore noa i te mimiti ā-rohe o te wai tere-rahi i runga i te nohoanga, engari ka horoia atu hoki te kohi i runga i te mata hiri kia tutuki ai te kaupapa o te horoi-ā-koe.
7, ko te diameter o te takirere he DN50 i raro i te tinana takirere, ko te uhi takirere he wāhanga hanga, ko te DN65 i runga ake i te tinana takirere, ko te uhi takirere he wāhanga maitai whakarewa.
8, he rerekē ngā momo hononga o te tinana takirere me te taupoki takirere, te hononga titi rawhi, te hononga gasket flange me te hononga miro hiri-whaiaro.
9. Ko te mata hiri o te nohoanga takirere me te taupoki takirere he mea hanga ki te whakarewa rehu plasma, ki te mata rānei he cobalt chromium tungsten carbide, he pakeke rawa, he ātete ki te kakahu, he ātete ki te pakū, ā, he roa te ora mahi.
10, ko te rauemi o te kakau takirere he rino nitriding, he pakeke te mata o te kakau takirere nitriding, he ātete ki te kakahu, he ātete ki te karawarawa, he ātete ki te waikura, he roa te ora ratonga.

✧ Ngā Painga o te Pōnati Porowhita Porowhita BS 1873

I te wā e whakatuwheratia ana, e kati ana hoki te takirere porowhita maitai hanga, nā te mea he iti ake te waku i waenga i te kōpae me te mata hiri o te tinana takirere i tērā o te takirere kuaha, ka ātete ki te kakahu.
He poto noa te whiu whakatuwheratanga, te whiu kati rānei o te kakau takirere, ā, he tino pono te mahi tapahi, ā, nā te mea he rite te huringa o te putanga nohoanga takirere ki te whiu o te kōpae takirere, he tino pai mō te whakatikatika i te tere rere. Nō reira, he tino pai tēnei momo takirere mō te tapahi, te whakahaere rānei me te whakawhāiti.
