Me tono koe i ngā takirere pōro mō tētahi kaupapa, engari kāore koe i te tino mōhio ki te rahi tuturu. Mēnā ka tono koe i te rahi hē, ka roa te wā, ka nui hoki ngā utu whakahoki, he mahi uaua kāore e hiahiatia ana e te kaiwhakahaere hoko.
Ko ngā rahi o ngā takirere pōro e ahu mai ana i te rahi paipa ingoa e hono atu ai. Ko te nuinga o te wā, mai i te 1/2 inihi te rahi mō te whakamahi kāinga ki te 12 inihi te rahi mō ngā mahi ahumahi, e whai ana i ngā paerewa o te ao pēnei i te NPS me te DN.
Ko te whakatau i te rahi tika te taahiraa matua mō te tono. He māmā noa iho te āhua, engari nā te rerekētanga o ngā paerewa e whakamahia ana puta noa i te ao, ka raru pea. Kei te mahi tahi mātou me ngā hoa mahi pērā i a Budi i Initonīhia, ā, me tino mārama mātou ki te rahi kia tino whiwhi ana kiritaki i te mea e hiahiatia ana e rātou mō ā rātou kaupapa. Mā te whakamahi i te rahi tika ka tika te taunga, ka pono te hiri, me te pūnaha e mahi ana i runga i te hoahoa. Ehara tēnei i te mea he wāhanga noa iho; engari he angitu te tāutanga katoa.
He aha ngā rahi o ngā takirere pōro?
Kei te titiro koe ki tētahi rārangi kaihoko, ā, te āhua nei he mutunga kore te rārangi o ngā rahi takirere. Kei te whakaaro koe ko ēhea ngā rahi mō ngā mahi noa, ko ēhea hoki mō ngā kaupapa ahumahi motuhake.
He whānuitanga nui ngā rahi o ngā takirere pōro hei taurite i ngā rahi paipa paerewa katoa. Mō te nuinga o ngā tono PVC, ko te nuinga o tēnei mai i te 1/2 inihi (DN15) ki te 12 inihi (DN300).
Ko te whānuitanga o ngā rahi e tohu ana hetakirere pōromō te nuinga o ngā mahi, mai i te mea māmā noa ihopā o te mārahononga ki tētahi puna wai nui. Ko te mea nui ko te mārama ki ngā rahi e whakamahia ana mō ngā tono. Hei kaihanga, ka rongoatia e mātou ngā rahi tino noa kia taea ai e ō mātou hoa mahi te tiki i ngā mea e hiahiatia ana e rātou me te kore e roa te wā arahi. Mō tētahi mākete pēnei i a Indonesia, he rite tonu te taonga o ngā whare noho me ngāngā rahinga whakamakukuHe mea nui te whānui mai i te 1/2″ ki te 4″ kia pai ai te mahi a Budi ki ana kiritaki. Mā tēnei ka taea e te kaimahi kirimana te kimi i te takirere e hiahiatia ana e rātou mō ngā mahi putorino me ngā mahi hanga o ia rā.
Ngā Kāwai Rahi me ngā Whakamahinga
| Awhe Rahi (Inihi) | Awhe Rahi (DN) | Ngā Whakamahinga Noa | Tauira Taupānga |
|---|---|---|---|
| Whare Noho Iti | 1/2″ – 1″ | DN15 – DN25 | Ngā whakaweto hiko takitahi, ngā paipa wai kāinga, ngā puna wai māra. |
| Pānui Waenga | 1-1/4″ – 4″ | DN32 – DN100 | Te hanga i ngā ara wai matua, ngā pūnaha whakamakuku arumoni, ngā puna kaukau. |
| Ahumahi Nui | 6 inihi me te ake | DN150 me runga ake | Ngā pūnaha wai ā-tāone, ngā raina tukanga wheketere, te ahuwhenua. |
He aha ngā rahi paerewa o ngā takirere?
Ka rongo koe i ngā kupu pēnei i te NPS, DN, Imperial, me te Metric. Ka raru pea te tono mai i ngā whenua rerekē, ā, ka tūpono pea te whiwhi i tētahi wāhanga kāore e tau ki ō paipa.
Ko ngā rahi o ngā takirere paerewa ka tautuhia e te pūnaha NPS (Nominal Pipe Size), e whakamahi ana i ngā inihi, i te pūnaha DN (Diameter Nominal) rānei, e whakamahi ana i ngā mirimita. Ka whakarite ngā pūnaha e rua i te hototahitanga ā-ao i waenga i ngā paipa me ngā hononga.
Ko ēnei paerewa te reo o te umanga paramu. I hangaia kia pai ai te uru o tētahi takirere i hangaia i tētahi whenua ki tētahi paipa i hangaia i tētahi atu whenua. Ko te tau rahi he "ingoa noa", arā, he ingoa mō te rahi, ehara i te ine tika. Kāore he whakatuwheratanga o tētahi takirere 2-inihi e rite ana ki te 2,000 inihi. He mea hanga kia uru ki tētahi paipa 2-inihi. Te mārama ki ngā mea e ruaNPSmeDNHe mea nui tēnei mō te hunga katoa e uru ana ki te hokohoko o te ao, pērā i ahau me ōku hoa mahi. Ka whakakorea ngā feaa katoa, ā, ka whakarite kia mahi tahi ngā wāhanga me te kore he raruraru.
Te Mārama ki ngā Paerewa NPS me te DN
Anei tētahi tūtohi tahuritanga māmā mō ngā rahi e tino kitea ana. Mā te whai i tēnei ka māmā ake te whakawhiti i waenga i ngā pūnaha e rua, ā, ka kore hoki e pōhēhē.
| NPS (Inihi) | DN (Mirimita) |
|---|---|
| 1/2″ | DN15 |
| 3/4″ | DN20 |
| 1 inihi | DN25 |
| 1-1/2″ | DN40 |
| 2 inihi | DN50 |
| 3 inihi | DN80 |
| 4 inihi | DN100 |
Me pēhea te tautuhi i te rahi o te takirere?
Kei te mahi koe i tētahi papa mahi, ā, me whakakapi he takirere tawhito. He paru te takirere, ā, kāore he takai, he pepa rānei, nō reira kāore koe i te tino mōhio he aha te rahi hei tono.
Hei tautuhi i te rahi o te takirere, tirohia te tinana takirere mō ngā tohu whakairo, tānga rānei. Ka kite koe i te ine inihi (hei tauira, “2″) he uara DN rānei (hei tauira, “DN50″).
Tata tonu ka tāpirihia e ngā kaihanga te tohu rahi ki runga i te hua. Koinei te huarahi tere me te huarahi pono ki te tautuhi. Tirohia marietia te tinana matua o te takirere. I ētahi wā ka kitea nuitia te tohu waitohu, te whakatauranga pēhanga rānei, engari ka kitea tonu te tohu rahi.ngā takirere pōro uniana pono, tērā pea ka kitea e koe te rahi kua tohua ki ngā nati uniana. Kia kitea e koe tēnei tau, ka taea e koe te tino māia ki te tono i te whakakapinga tika. Mā tēnei tirotiro ngāwari ka penapenahia he nui te wā, ā, ka ārai i te pouri o te whiwhi i te wāhanga hē.
Me aha mēnā kāore he tohu
Mena kua tawhito rawa te takirere, kua pakaru rānei, ā, kāore e kitea he tohu, he iti noa ngā kōwhiringa. Kaua e ine noa i te taha o waho o te takirere, nā te mea ka hē pea tēnei.
- Tirohia te Paipa:Koinei te tikanga pai rawa atu. Ka tāia te rahi o te paipa e honoa ana te takirere ki tōna roa. Rapua ngā tohu pēnei i te "PVC Schedule 40 2 INCH" me te "UPVC PN10 DN50". Ka ōrite te rahi o te takirere ki te rahi o te paipa.
- Inehia te Putanga o Roto:Āta inehia te whānui o roto o te pūaha e rere ana te wai. Ka tata rawa tēnei ine ki te rahi ingoa. Hei tauira, ko te whānui o roto o te takirere 2-inihi ka tata ki te 2 inihi.
- Whakatauritea ki tētahi Takirere Mōhiotia:Mena kei a koe ētahi atu takirere e mōhiotia ana te rahi, ka taea e koe te whakarite tika i tētahi mea ā-tinana.
He aha te tikanga o te DN50 i runga i te takirere?
Kei te arotake koe i tētahi pepa whakatakotoranga hangarau mai i tētahi kaiwhakarato Pākehā. Ka kite koe i te "DN50" ā, me mōhio koe ki te rahi e mārama ai tō tīma ā-rohe.
Ko te tikanga o te DN50 ko "Diameter Nominal 50 millimeters". Koinei te rahi paerewa o te ao e rite ana ki te rahi 2-inihi (NPS) e whakamahia ana i te Hononga o Amerika me ētahi atu rohe.
"Ka hangaia e te pūnaha DN he paerewa whānui mō te katoa."Diameter Ingoa"Ko te tikanga he ingoa noa iho tēnei mō te rahi, ehara i te ine tino tika. Mā te whakamahi i te DN, ka taea e te kaiwhakahaere kaupapa i Initonīhia pērā i a Budi te tono mai i tētahi kaihanga pērā i ahau i Haina, ā, e mōhio ana māua ki tā māua e kōrero nei. Ka whakakorea te whakapoauautanga i waenga i ngā pūnaha ine me ngā pūnaha imperia, ā, koinei te tūāpapa o te hototahitanga ā-ao i roto i tā mātou umanga. Ina kite koe i te DN, ka mōhio koe kei te whakamahi koe i tePaerewa ISOMā tēnei ka taea te whakarite kia uru te takirere DN50 ki tētahi paipa, ki tētahi hononga DN50 rānei, ahakoa nō hea i hangaia ai.
Ngā Rahi DN Noa me ō rātou Taurite Inihi
He mea nui te mārama ki tēnei whanaungatanga mō te mahi tahi me ngā hua o te ao.
| Rahi DN | Tikanga Tika | Taurite Inihi Noa (NPS) |
|---|---|---|
| DN15 | Diameter Ingoa 15 mm | 1/2″ |
| DN25 | Diameter Ingoa 25 mm | 1 inihi |
| DN50 | Diameter Ingoa 50 mm | 2 inihi |
| DN100 | Diameter Ingoa 100 mm | 4 inihi |
Mā tēnei whakaritenga ka taea e tātou te hanga pūnaha wai pono i te ao whānui.
Whakamutunga
Te māramatangangā rahi o te takirere pōrohe mea nui mō te tono i ngā wāhanga tika. Mā te mōhio ki ngā pūnaha paerewa pēnei iNPS me te DNā, me pēhea te kimi i te rahi o te takirere, ka karohia e koe ngā hapa utu nui.
