Tetakirere pūrerehua kirihouKa honoa ki te pūnaha paipa i ngā huarahi e whai ake nei:

Hononga whakarewa pūtu: Ko te diameter o waho o te wāhanga hononga takirere he rite ki te diameter o waho o te paipa, ā, ko te mata pito o te wāhanga hononga takirere kei te ritenga atu o te mata pito o te paipa mō te whakarewa;

Hononga hononga pūwero: ko te wāhanga hononga takirere kei te āhua o te pūwero, e herea ana ki te paipa;

Hononga pūwero hiko: ko te wāhanga hononga takirere he momo pūwero me te waea whakamahana hiko e whakatakotoria ana ki te diameter o roto, ā, he hononga hiko ki te paipa;

Hononga rewa-wera o te hononga: ko te wāhanga hononga takirere he rite ki te hononga, ā, ka honoa ki te paipa mā te hononga rewa-wera;

Hononga hononga pūwero: Ko te wāhanga hononga takirere he rite ki te pūwero, e honoa ana, e whakapūwerohia ana ki te paipa;

Hononga mowhiti hiri rapa tūhono: Ko te wāhanga hononga takirere he momo tūhono me te mowhiti hiri rapa i roto, he tūhono me te hono ki te paipa;

Hononga flange: Ko te wāhanga hononga takirere kei te āhua o te flange, e hono ana ki te flange i runga i te paipa;

Hononga miro: Ko te wāhanga hononga takirere he miro te āhua, e honoa ana ki te miro o te paipa, ki te hononga paipa rānei;

Hononga ora: Ko te wāhanga hononga takirere he hononga ora, e hono ana kingā paipa, ngā hononga rānei.

Ka taea e te takirere te whakamahi i ngā momo hononga rerekē i te wā kotahi.

te kaupapa mahi:

Ko te whanaungatanga i waenga i te whakatuwheratanga o te takirere pūrerehua kirihou me te tere rere ka rerekē haere i te taha rārangi. Mena ka whakamahia hei whakahaere i te rere, ka pā tata hoki ōna āhuatanga rere ki te ātete rere o ngā paipa. Hei tauira, e rua ngā paipa kua tāutahia me te diameter me te āhua o te takirere, engari he rerekē te tauwehenga ngaronga o te paipa, ā, ka tino rerekē hoki te tere rere o te takirere.

Mena kei roto te takirere i tētahi āhua e nui ana te awhe whakatere, ka ngāwari te tuara o te pereti takirere ki te pakaru, ka kino pea te takirere. I te nuinga o te wā, ka whakamahia i waho o te 15°.

Ina kei waenganui te takirere pūrerehua kirihou, ko te āhua o te whakatuwheratanga i hangaia e te tinana takirere me te pito o mua o te pereti pūrerehua ka pokapū ki te kakau takirere, ā, ka hangaia ngā taha e rua hei whakaoti i ngā āhua rerekē. Ko te pito o mua o te pereti pūrerehua i tetahi taha ka neke i te ahunga o te rere o te wai, ā, ko tetahi taha kei te whakahē i te ahunga o te rere. Nō reira, ko tetahi taha o te tinana takirere me te pereti takirere ka hanga he whakatuwheratanga rite ki te pūwero, ā, ko tetahi taha he rite ki te whakatuwheratanga o te pūwero. He tere ake te rere o te taha pūwero i te taha pūwero, ā, ka puta he pēhanga kino i raro i te takirere taha pūwero. He maha ngā wā ka taka ngā hiri rapa.

Kāore he āheinga raka-ā-koe o ngā takirere pūrerehua kirihou me ngā tokotoko pūrerehua. Mō te whakanoho i te pereti pūrerehua, me tāuta he taputapu whakaiti noke ki te tokotoko takirere. Mā te whakamahi i te taputapu whakaiti noke, ehara i te mea ka taea anake te raka-ā-koe o te pereti pūrerehua, ka mutu hoki te pereti pūrerehua i tētahi tūranga, engari ka whakapai ake hoki i te mahi a te takirere.

He rerekē ngā uara o te taipana whakahaere o te takirere pūrerehua kirihou nā te rerekētanga o ngā ahunga whakatuwheratanga me te kati o te takirere. Mō te takirere pūrerehua whakapae, inā koa te takirere whānui, nā te hohonutanga o te wai, kāore e taea te wareware i te taipana i hangaia e te rerekētanga i waenga i ngā pane wai o runga me raro o te pou takirere. Hei tāpiri, ina tāutahia te tuke ki te taha tomo o te takirere, ka puta he rere whakarara, ā, ka piki ake te taipana. Ina kei waenganui te takirere, me raka-ake te pūnaha whakahaere nā te mahi a te taipana rere wai.

He māmā te hanganga o te takirere pūrerehua kirihou, he torutoru noa ngā wāhanga, ā, he iti te whakamahinga o ngā rauemi; he iti te rahi, he māmā te taumaha, he iti te rahi o te tāutanga, he iti te taipana taraiwa, he māmā, he tere te whakahaere, me huri noa i te 90° kia tere te whakatuwhera me te kati; ā, i te wa ano, he pai te mahi whakatikatika rere me ngā āhuatanga kati me te hiri. I roto i te mara tono o te pehanga nui me te reo, te pehanga reo me te iti, ko te takirere pūrerehua te ahua takirere matua. Ina kei te tūranga tuwhera katoa te takirere pūrerehua, ko te matotoru o te pereti pūrerehua anake te ātete ina rere te reo i roto i te tinana takirere, nō reira he iti te hekenga pehanga i hangaia e te takirere, nō reira he pai ake ngā āhuatanga whakahaere rere. E rua ngā momo hiri o te takirere pūrerehua: te hiri rapa me te hiri whakarewa. Ko te takirere hiri rapa, ka taea te whakaniko i te mowhiti hiri ki runga i te tinana takirere, te tāpiri rānei ki te taha o te pereti pūrerehua. Ko ngā takirere me ngā hiri whakarewa he roa ake te ora i ngā takirere me ngā hiri rapa, engari he uaua ki te whakatutuki i te hiri katoa. Ka taea e te hiri whakarewa te urutau ki te pāmahana mahi teitei ake, ko te hiri rapa he hapa na te pāmahana. Mena me whakamahi te takirere pūrerehua hei whakahaere rere, ko te mea nui ko te whiriwhiri tika i te rahi me te momo o te takirere. He tino pai te kaupapa hanganga o te takirere pūrerehua mō te hanga takirere whānui. Kāore i te whakamahia whānuitia ngā takirere pūrerehua i roto i ngā ahumahi whānui pēnei i te hinu, te hau, te matū, me te maimoatanga wai anake, engari ka whakamahia hoki i roto i ngā pūnaha wai whakamatao o ngā teihana hiko wera. Ko ngā takirere pūrerehua e whakamahia whānuitia ana ko ngā takirere pūrerehua momo wafer me ngā takirere pūrerehua momo flange. Ka honoa ngā takirere pūrerehua wafer i waenga i ngā flange paipa e rua me ngā pūtu poutū. Ko ngā takirere pūrerehua flange he flange kei runga i te takirere. Ka honoa ngā flange i ngā pito e rua o te takirere ki ngā flange paipa me ngā pūtu. Ko te kaha o te takirere e pā ana ki te kaha o te takirere ki te tu atu i te pēhanga o te reo. He hua miihini te takirere e mau ana i te pēhanga o roto, nō reira me nui te kaha me te pakari kia roa ai te whakamahinga me te kore e pakaru, e rerekē rānei te āhua.

Mā te whakamahi i te rapa hangai ārai-waikura me te polytetrafluoroethylene, ka taea te whakapai ake i te mahi a ngā takirere pūrerehua, ā, ka tutuki i ngā āhuatanga mahi rerekē. I roto i ngā tau tekau kua pahure ake nei, kua tere te whanaketanga o ngā takirere pūrerehua hiri whakarewa. Mā te whakamahi i te ātete pāmahana teitei, te ātete pāmahana iti, te ātete waikura kaha, te ātete horo kaha, me ngā rauemi koranu kaha teitei i roto i ngā takirere pūrerehua, kua whakamahia ngā takirere pūrerehua hiri whakarewa i roto i ngā pāmahana teitei, pāmahana iti, me te horo kaha. Kua whānuitia te whakamahinga i raro i ētahi atu āhuatanga mahi, ā, kua whakakapia te takirere porowhita i tētahi wāhanga.takirere kuahame te takirere pōro.
