I roto i te awheawhe Jinbin, he tini ngāngā takirere porowhitakei te tirotirohia whakamutunga. E ai ki ngā hiahia o te kiritaki, ko te rahi kei waenga i te DN25 ki te DN200.（2 Inihi te takirere porowhita）

Hei takirere noa, ko ngā āhuatanga matua o te takirere porowhita e whai ake nei:

1. Mahi hiri tino pai: He piri te hanganga hiri matua i waenganui i te kōpae takirere me te nohoanga takirere. Ina kati, ka pēhia te kōpae takirere ki te nohoanga takirere i raro i te pēhanga, ka tutuki he tapahi piri. He pai mō ngā tono e tika ana kia āraihia te turuturu waenga (pērā i ngā paipa hau me te mamaoa).

2. Mahi whakahaere tino pai: Ka piki, ka heke te kōpae takirere i te tuaka o te kakau takirere, ā, ka taea te whakarite tika i te tere rere mā te whakahaere i te tohu whakatuwheratanga. Ka huri maeneene te tere rere mai i te tuwhera katoa ki te kati katoa, kia pai ai mō ngā āhuatanga e hiahia ana kia pai te whakahaere rere (pēnei i te whakatikatika pāmahana i roto i ngā pūnaha whakamahana).

3. Ātete rere nui: Me huri te reo, ā, me rere ki waho i muri i te haerenga mā te nohoanga takirere, me te ara pikopiko. He nui ake te ngaronga pēhanga i ērā o ngā takirere tika pērā i ngā takirere kuaha. Nō reira, kāore e pai mō ngā paipa he nui te rere me te iti o te ātete e hiahiatia ana (pērā i te paipa matua e tuku wai ana).

4. Tāutanga Aronga: Me tāuta kia rite ki te mātāpono "iti ki roto, teitei ki waho" (ka rere te reo mai i raro i te kōpae takirere), me te whakarite kia āwhinahia te kōpae takirere ki te hiri e te pēhanga reo ina kati, ā, kia māmā te mahi. Mā te tāuta whakamuri ka pakaru te hiri, ka uaua hoki te mahi.

5. He whānuitanga o ngā rauemi e tika ana: Ka taea te whakamahi mō ngā rauemi ma pēnei i te wai, te mamaoa, ngā hua hinu, me te hau, engari kāore e pai mō ngā rauemi matotoru, ngā rauemi kirikiri rānei (nā te mea ka ngāwari te pakaru o te mata hiri me te kino o te mahi hiri).

I runga i ēnei āhuatanga, e whakamahia whānuitia ana ngā takirere aukati i roto i ngā āhuatanga e hiahia ana kia kati rawatia, kia tika hoki te whakahaere:

1. Pūnaha tuku wai me te rerenga wai: Hei takirere whakahaere porowhita mō ngā paipa peka, ka tapahia, ka whakahaeretia rānei te nui o te wai hei whakarite i te mana whakahaere ā-rohe o te whatunga paipa.

2. Pūnaha mamaoa: Whakamutua te tuku mamaoa, whakahaeretia rānei te tere rere o ngā paipa mamaoa ahumahi, ā, whakamahia tōna āhuatanga hiri hei ārai i te turuturu o te mamaoa me te ngaronga o te pūngao.

3. Ahumahi hinu: I te wa e kawe ana i te hinu mata, nga whakarewa me etahi atu pāpāho, ka whakahaerehia te tere rere ma te whakatikatika i te tohu whakatuwheratanga kia tutuki ai nga whakaritenga whangai o te taputapu tauhohenga.

4. Ngā pūnaha whakamahana me te hauhautanga: Whakahaere i te rere o te wai wera, te hauhautanga rānei, kia tika ai te whakahaere i te pāmahana o te rūma, kia pai ake ai te whakamahinga o te pūngao.

Ngā paipa hau me te hau kōpeke: Hei takirere ārai haumaru, ka kati wawe i te wā tiaki, i te wā hapa rānei hei ārai i te turuturu waenga me ngā aituā haumaru pea.

Nā ngā painga o te hiri pono me te whakahaere ngāwari, kua noho te flanged globe valve hei wāhanga matua o ngā pūnaha paipa e whakakotahi ana i ngā mahi tapahi me te whakahaere. He mea tino nui te whakakapi i roto i ngā horopaki he diameter waenga me te iti, ā, he nui ngā whakaritenga mō te hiri me te whakahaere.（Te Utu o te Globe Valve）
