Kei raro nei he whakarāpopototanga o te whānuitanga diameter o ngā takirere pūrerehua me ngā tikanga hononga me ngā momo hanganga rerekē, i runga i ngā paerewa ahumahi me ngā mahi tono noa. I te mea ka rerekē pea te whānuitanga diameter motuhake i runga i te kaihanga me te horopaki tono (pēnei i te taumata pēhanga, te momo waenga, me ētahi atu), ka whakaratohia e tēnei tuhinga ngā raraunga mō ngā takirere zfa.
Ko ngā raraunga tohutoro whānui e whai ake nei i te diameter ingoa (DN, mm).
1. Te whānuitanga o te diameter o ngā takirere pūrerehua kua whakarōpūtia e te tikanga hononga
1. takirere pūrerehua angiangi
- Awhe whānui: DN15–DN600
- Whakaahuatanga: He kiato te hanganga o ngā takirere pūrerehua wafer, ā, he maha ngā wā ka whakamahia i roto i ngā pūnaha pēhanga reo me te iti. He whānui te whānuitanga o te diameter, ā, he pai mō ngā paipa iti me te rahi reo. Mena ka neke atu i te DN600, ka taea e koe te whiriwhiri i tētahi takirere pūrerehua flange kotahi (DN700-DN1000). He onge ngā diameter tino nui (pērā i te DN1200 i runga ake) nā te mea he nui ngā whakaritenga tāutanga me te hiri.
2. Takirere pūrerehua takirua
- Awhe whānui: DN50–DN3000
- Whakaahuatanga: He pai te takirere pūrerehua takirua mō ngā wā e hiahia ana kia nui ake te pumau o te hanganga me te mahi hiri. He whānui ake te whānuitanga o tōna diameter, ā, he maha ngā wā ka whakamahia i roto i ngā pūnaha paipa nui pēnei i te maimoatanga wai, ngā teihana hiko, me ētahi atu.
3. Takirere pūrerehua kotahi-flange
- Awhe whānui: DN700–DN1000
- Whakaahuatanga: He iti ake ngā rauemi e pau ana i ngā takirere kotahi-pere i ngā takirere takirua-pere, ka whakaitihia hoki ngā utu hanga me ngā utu kawe. Ka herea ki te takirere paipa, ka whakamāuhia ki tōna tūranga.
4. Takirere pūrerehua
- Awhe whānui: DN50–DN600
- Whakaahuatanga: He pai ngā takirere pūrerehua lug (momo lug) mō ngā pūnaha kei te pito o te paipa, e hiahia ana rānei kia wetewetehia i ngā wā katoa. He iti, he waenga hoki te whānuitanga o te diameter. Nā ngā herenga hanganga, he iti ake te maha o ngā whakamahinga diameter nui.
5. Takirere pūrerehua momo-U
- Awhe o te kaha: DN100–DN1800
- Whakaahuatanga: Ko ngā takirere pūrerehua momo-U e whakamahia ana mō ngā paipa whānui-rahi, pērā i te tuku wai ā-tāone, te maimoatanga paru, me ētahi atu, ā, he pai te hanganga mō ngā āhuatanga rerekētanga pēhanga teitei me te pēhanga iti.
| Whakaahuatanga | Awhe Rahi Noa (DN) | Ngā Tuhipoka Matua |
|---|---|---|
| Takirere Pūrerehua Wai | DN15-DN600 | He hanganga kiato, he iti te utu, he whānui te whakamahinga i roto i ngā pūnaha pēhanga iti-ki-waenga; he rahi ake mō ngā ratonga kore-tino nui. |
| Takirere Pūrerehua | DN50-DN600 | He pai mō ngā ratonga mutunga kore me ngā pūnaha e hiahia ana kia wetewetehia mai i te taha kotahi. He pai ake te whakahaere pēhanga i te momo wai. |
| Takirere Pūrerehua Kotahi-Flanged | DN700-DN1000 | He mea noa i roto i ngā pūnaha tanumia, i ngā pūnaha pēhanga iti rānei; he mama ake, he ngāwari hoki te tāuta. |
| Takirere Pūrerehua Takirua-Flanged | DN50-DN3000 (tae atu ki te DN4000 i ētahi wā) | He pai mō ngā mahi pēhanga teitei, te whānui nui, me ngā mahi tino nui; he tino pai te mahi hiri. |
| Takirere Pūrerehua Momo-U | DN50-DN1800 | He tikanga he rapa te whakakī, he whakakī katoa rānei hei ātete ki te waikura i roto i ngā ratonga matū. |

2. Te whānuitanga o ngā takirere pūrerehua kua whakarōpūtia e te momo hanganga
1. Takirere pūrerehua raina waenganui
- Awhe o te kaha: DN50–DN1200
- Whakaahuatanga: He hanganga māmā te takirere pūrerehua raina-waenga (hiri ngohengohe, hiri rapa rānei), e tika ana mō ngā pāpāho pēhanga iti me te pāmahana noa, whānuitanga āhua taurite, ā, e whakamahia whānuitia ana i roto i te wai, te hau me ētahi atu pūnaha.
2. Takirere pūrerehua rerekē takirua
- Awhe o te kaha: DN50–DN1800
- Whakaahuatanga: Ka whakaitihia e te takirere pūrerehua rerekē takirua te pakaru o te hiri mā te hoahoa rerekē, he pai mō ngā pūnaha pēhanga iti me te pēhanga waenga, he whānui te whānuitanga o te kounga, ā, he mea whakamahi noa i roto i te hinu me te hau, te matū me ētahi atu ahumahi.
3. Takirua pūrerehua rerekē toru
- Awhe o te kaha: DN100–DN3000
- Whakaahuatanga: He pai te takirere pūrerehua rerekē-toru (hiri mārō) mō ngā pāmahana teitei, te pēhanga teitei me ngā āhuatanga mahi uaua. He whānuitanga nui tōna, ā, he maha ngā wā ka whakamahia i roto i ngā paipa ahumahi nui, pērā i te hiko, te matū hinu, me ētahi atu.
| Whakaahuatanga | Awhe Rahi Noa | Ngā Tuhipoka Matua |
|---|---|---|
| Takirere Pūrerehua Kōpikopiko | DN40-DN1200 (tae atu ki te DN2000 i ētahi wā) | He maeneene te whakanoho o ngā raina waenganui o te kakau me te kōpae, he pai mō ngā mahi whānui me te iti o te pēhanga. |
| Takirere Pūrerehua Āpitihanga Takirua | DN100-DN2000 (tae atu ki te DN3000) | Ka tere te wete o te kōpae i te nohoanga i te wā e tuwhera ana hei whakaiti i te pakaru, ā, ka whakamahia i roto i ngā āhuatanga pēhanga-waenga. |
| Takirere Pūrerehua Āpitihanga Toru | DN100-DN3000 (tae atu ki te DN4000) | I hangaia mō ngā mahi pāmahana teitei, pēhanga teitei, kore turuturu, ko te nuinga o te wā ka noho ki runga i te mea whakarewa. |
