I tēnei rā, he puranga ongā takirere pūrerehua e whakahaerehia ana e te kakauKua oti te hanga, ko ngā whakatakotoranga o tēnei puranga takirere pūrerehua ko DN125, ko te pēhanga mahi ko 1.6Mpa, ko te reo e tika ana ko te wai, ko te pāmahana e tika ana he iti iho i te 80℃, ko te rauemi tinana he mea hanga ki te rino ngawari, he kaha me te pakari teitei, nō reira he pai te ātete pānga me te roa o tēnei takirere.

Ko te kaupapa mahi o tetakirere pūrerehua tinana rino makaHe tino māmā noa iho, ko te nuinga o te mea he tinana takirere, he kōpae takirere, he kakau takirere me te kakau. Ina hurihia te kakau ki te taha matau, ka tata te kōpae takirere ki te rārangi pokapū o te tinana takirere, ā, ka āta kati te takirere. Ina hurihia te kakau ki te taha maui, ka neke atu te kōpae takirere i te rārangi pokapū o te tinana takirere, ā, ka āta tuwhera te takirere. Mā te whakarerekē i te koki hurihuri o te kakau, ka taea te whakahaere tika i te nui o te whakatuwheratanga o te takirere, kia pai ai te whakahaere i te rere o te wai. Hei tāpiri, kei te kakau hei here i te takirere pūrerehua he mowhiti hiri, ina kati te takirere, ka hanga he hiri piri te kōpae takirere me te tinana hei ārai i te turuturu wai.

Mā te hoahoa o te pupuri ka taea te mahitakirere pūrerehua waferHe māmā ake, he māmā ake hoki. Ka hurihia noa e te kaiwhakamahi te kakau hei whakatuwhera me te kati i te takirere, me te kore he mahi uaua, he taputapu motuhake rānei. Ehara i te mea ka whakapai ake tēnei hoahoa i te whai huatanga o te mahi, engari ka whakaitihia hoki te uaua o te whakahaere, ka māmā ake te tiaki me te whakakapi i te takirere.

Ko te hoahoa o tetakirere pūrerehua ā-ringaka whakaarohia hoki te ngāwari o te tiaki, ā, ka taea te tango me te whakakapi i ngā wāhanga katoa, ka whakaiti i te wā me te uaua o te tiaki.
