Te tirotiro i mua i te tāutanga o te takirere

① Tirohia marietia mēnā e tutuki ana te tauira me ngā whakaritenga o te takirere i ngā whakaritenga tuhi.

② Tirohia mēnā he ngāwari te whakatuwheratanga o te kakau takirere me te kōpae takirere, ā, mēnā he piri, he piko rānei.

③ Tirohia mēnā kua pakaru te takirere, ā, mēnā kei te tika, kei te ora tonu hoki ngā miro o te takirere miro.

④ Tirohia mēnā he pakari te hononga i waenga i te nohoanga takirere me te tinana takirere, te hononga i waenga i te kōpae takirere me te nohoanga takirere, te taupoki takirere me te tinana takirere, me te kakau takirere me te kōpae takirere.

⑤ Tirohia mēnā he pai te gasket, te takai me ngā pūmau (poro) mō ngā whakaritenga o te āhua o te rauemi mahi.

⑥ Me wetewete ngā takirere whakaiti pēhanga kua tawhito, kua waiho rānei mō te wā roa, ā, me horoi te puehu, te onepu me ētahi atu paru ki te wai.

⑦ Tangohia te taupoki hiri o te putanga, ka tirohia te nui o te hiri. Me kati pūmau te kōpae takirere.

Whakamātautau pēhanga takirere

Me whakamātautau te kaha me te piri o ngā takirere pēhanga iti, pēhanga waenga me te pēhanga teitei. Me whakahaere hoki e ngā takirere maitai koranu he tātaritanga ā-ira i runga i ngā anga takitahi, me te arotake i ngā rauemi.

1. Whakamātautau kaha o te takirere

Ko te whakamātautau kaha o te takirere he whakamātautau i te takirere i te āhua tuwhera hei tirotiro i te turuturu i te mata o waho o te takirere. Mō ngā takirere me te PN ≤ 32MPa, ko te pēhanga whakamātautau he 1.5 ngā wā o te pēhanga ingoa, ko te wā whakamātautau kāore e iti iho i te 5 meneti, ā, kāore he turuturu i te anga me te repe tākai hei tohu.

2. Whakamātautau i te piri o te takirere

Ka whakahaerehia te whakamātautau me te takirere kua kati katoa hei tirotiro mēnā he turuturu kei runga i te mata hiri o te takirere. Ko te pēhanga whakamātautau, haunga ngā takirere pūrerehua, ngā takirere tirotiro, ngā takirere raro me ngā takirere whakatere, me whakahaere i te pēhanga noa. Ina taea te whakatau i te pēhanga mahi, ka taea hoki te whakahaere i te whakamātautau i te 1.25 ngā wā o te pēhanga mahi, ā, me tohu te mata hiri o te kōpae takirere mēnā kāore e turuturu.

Ngā ture whānui mō te tāutanga o te takirere

1. Kaua te tūranga tāutanga o te takirere e aukati i te mahi, te wetewete me te tiaki i ngā taputapu, ngā paipa me te tinana takirere tonu, ā, me whai whakaaro ki te āhua ataahua o te huihuinga.

2. Mō ngā takirere i runga i ngā paipa whakapae, me tāuta te kakau takirere ki runga, ki te koki rānei. Kaua e tāuta te takirere me te wira ringa ki raro.

3. He ōrite te whakatakotoranga, he ātaahua, he ātaahua hoki; mō ngā takirere i runga i te paipa tū, ki te taea e te tukanga, ko te wira ringaringa takirere te mea tino pai kia whakahaerehia i te teitei o te uma, ko te tikanga he 1.0-1.2m mai i te whenua, ā, me whai te kakau takirere i te whakatakotoranga a te kaiwhakahaere.

4. Mō ngā takirere i runga i ngā paipa poutū taha-ki-taha, he pai ake kia rite te teitei o te rārangi pokapū, ā, kaua te tawhiti mārama i waenga i ngā wira ringaringa e iti iho i te 100mm; mō ngā takirere i runga i ngā paipa whakapae taha-ki-taha, me whakanekeneke kia whakaitihia te tawhiti i waenga i ngā paipa.

5. Me tāuta ngā whāriki takirere ina tāutahia ngā takirere taumaha ake ki ngā papu wai, ki ngā whakawhiti wera me ētahi atu taputapu; me tāuta he papa whakahaere pumau ina whakamahia pinepinetia ngā takirere, ā, ina tāutahia kia neke atu i te 1.8m te tawhiti atu i te mata whakahaere.

6. Mena he tohu pere kei te tinana o te takirere, ko te ahunga o te pere ko te ahunga rere o te reo. I te wā e tāuta ana i te takirere, kia tino rite te ahunga o te pere ki te ahunga rere o te reo i roto i te paipa.

7. I te wā e tāuta ana i ngā takirere flange, kia tino whakarara, kia ōrite hoki ngā mata pito o ngā flange e rua tetahi ki tetahi, ā, kāore e whakaaetia ngā gasket takirua.

8. I te wā e tāuta ana i tētahi takirere miro, kia māmā ai te wetewete, me whai hononga te takirere miro. Me whai whakaaro te whakatakotoranga o te hononga ki te ngāwari o te tiaki. I te nuinga o te wā, ka rere te wai mā roto i te takirere tuatahi, kātahi ka rere mā roto i te hononga.

Ngā whakatūpato mō te tāutanga o te takirere

1. He rino maka te nuinga o te rauemi o te tinana takirere, he pakarukaru, ā, kaua e pāngia e ngā mea taumaha.
