Nō nā tata nei, kua oti i te awheawhe o Jinbin te whakaoti i tētahi puranga ota mō ngā takirere pōro kua oti te whakarewa. Ko tetakirere pōro kua oti te whakarewahe hanganga whakarewa kua whakauruhia. Ka hangaia te tinana takirere mā te whakarewa i ngā taha e rua. Ko te wāhanga matua o roto he pōro me te kōhao porohita, e hono ana ki te kaiwhakaoho o waho mā te kakau takirere. Ina whakahaerehia, ko teflange takirere pōroka peia te kākano kia hurihuri mā roto i te kakau, te pouaka miihini, te taputapu hiko/haumanu rānei.

Ngā painga o te whakamahi i te umanga takirere pōro kua oti te whakarewa:

1. Hanganga pono me te mahi hiri kaha

Mā te tukanga whakarewa whānui ka whakakorea ngā tūponotanga turuturu o ngā hononga flange tuku iho, ā, he pai hoki mō ngā āhuatanga mahi uaua pērā i te pēhanga teitei, te mura me te pahū (hei tauira, ka taea e te pēhanga o ngā paipa hau māori te eke ki runga ake i te 10MPa). He ātete te rauemi hiri ki te kakahu, ā, he roa ake te ora mahi mō te neke atu i te 10 tau, ka whakaiti i te auau o te tiaki.

2. He iti te ātete rere me te rerenga katoa

He rite te kōhao porowhita ki te diameter o roto o te paipa, ā, ko te ātete rere o te reo he 1/10 noa iho o te ātete o te paipa o te roa ōrite, ka whakaiti i te whakapaunga pūngao. He tino pai mō te kawe tere (hei tauira, ka taea e te diameter o te paipa hinu mata te eke ki te 1200mm).

3. Ātete ki te waikura, ā, ka taea te urutau ki ngā taiao kino

Ko te tinana o te takirere pōro kowiri tira kua pania ki te paninga ārai-waikura kowiri tira, ki te paninga ārai-waikura waro rānei (pērā i te kapia epoxy), ka taea te ātete ki te waikura oneone me te horo o te wai moana, ā, he pai mō ngā āhuatanga uaua pēnei i te whenua me te wai.

4. He ngāwari ki te whakahaere me te iti o te utu tiaki

Mā te hurihanga 90° ka taea te whakatuwhera me te kati. Ka taea te whakahaere mamao mā te hono atu ki te pūnaha whakahaere aunoa. Ka whakaitihia e ngā hanganga whakarewa ngā wāhanga neke, ka iti te tere o te rahunga, ā, ka taea te whakaroa i te huringa tiaki ki te neke atu i te rima tau.

Ngā āhuatanga tono motuhake o te takirere pōro miihini kua oti te whakarewa:

Pūnaha paipa tawhiti

Te tuku hau māori – e whakamahia ana i roto i ngā raina pūtake hau māori o uta (pērā i te Paipa Hau o te Uru-Rawhiti) me ngā paipa tuku hau o raro i te wai, ka taea e ia te tu atu i te pēhanga teitei me te whakarite kia hiritia mō te wā roa hei ārai i ngā aituā haumaru i puta mai i te turuturu hau māori.

Te kawe hinu mata/hinu kua parakore – Mā te hoahoa poka-katoa e whakahaere te ahunga rere o te wai i roto i ngā paipa hinu whakawhiti-rohe, ka whakaitihia te pupuri hinu me te hekenga pēhanga e te hoahoa hinu-katoa, ā, ka whakapai ake i te whai huatanga o te kawe.

2. Ngā whatunga paipa hau me te whakamahana o te tāone

Ka tanumia, ka tāutahia ki roto i te paipa hau matua o te tāone hei whakahaere i te taunga oneone me ngā rerekētanga pāmahana, me te whakaiti i te tūponotanga o te turuturu. Whakahaerehia te rere o te wai wera i roto i te pūnaha whakamahana pokapū, me te tu atu ki te pēhanga teitei (1.6MPa) me te pāmahana teitei (120℃).

3. Mara ahumahi

Ahumahi matū: Te kawe i ngā mea waikura pērā i ngā waikawa kaha me ngā kawakore kaha. Mā ngā rauemi kowiri tira me ngā hanganga hiri pakari o te konganuku ka noho haumaru (pērā i ngā paipa waikawa hauwai me te houra tunutunu).

Te whakarewa me te hiko: Ka taea e ia te tapahi tere i te rere o te hau i roto i ngā paipa hau oumu pupuhi, te whakahaere rānei i te tere rere i roto i ngā paipa wai whakamatao o ngā tipu hiko wera, kia urutau ai ki ngā taiao pāmahana teitei (neke atu i te 300℃) me te puehu.

4. Te Hangarau Moana me ngā Waka

E whakamahia ana i roto i ngā paipa hinu o ngā papaaho taimoana me ngā pūnaha wahie kaipuke, he ātete ki te waikura o te wai moana, ā, he kaha ki te tu atu i ngā wiri kaipuke, ā, e tutuki ana i ngā paerewa o te ao pēnei i te API 6D.

Ko te takirere pōro Pn16 kua oti te whakarewa katoa, me tōna pono teitei, te utu tiaki iti me te whānui o te urutau ki ngā āhuatanga mahi, kua noho hei wāhanga whakahaere matua i roto i te tuku pūngao, ngā tukanga ahumahi me te hanganga hanganga, he mea tino nui te whakakapi i roto i ngā pūnaha paipa nui e hiahia ana ki te mahi pumau mo te wa roa.
