Mā te whiriwhiri i te momo miro hē mō ō hononga PVC ka pā mai ngā turuturu whakarihariha. Ka pā mai ēnei turuturu ki te kino o te wai, ka whakaroa i te kaupapa, ā, ka akiaki i a koe ki te mahi anō i te mahi, ka pau te wā me te moni.

He paerewa rerekē te NPT me te BSPT, kāore e hototahi. Ko te NPT te paerewa Amerikana me te koki miro 60°. Ko te BSPT te paerewa Piritana me te koki miro 55°. Me taurite te momo miro ki tō paipa.

He kaupapa tēnei e kōrerohia pinepinetia ana e au me taku hoa a Budi i Initonīhia. I roto i te hokohoko o te ao, ko ngā kōrero iti pēnei i tengā paerewa miroka taea te hanga i tētahi rerekētanga nui. I ētahi wā ka whakamahia e te mākete o te Tonga-Rawhiti o Āhia te paerewa ANSI o Amerika, tae atu ki te NPT, inā koa mō ngā kaupapa motuhake. Heoi, he maha ngā rohe e pai ake anaBSPTKo te mārama ki te rerekētanga matua i waenga i ēnei e rua te taahiraa tuatahi ki te tono i ngā wāhanga tika, me te whakarite kia taea e ō kiritaki te hanga pūnaha kaha, kore turuturu. Me titiro tātou ki ngā mea e wehewehe ana i a rāua.

He aha te rerekētanga tūturu i waenga i ngā miro BSPT me NPT?

He tata rite tonu te āhua o ngā miro o ngā hononga e rua. Mēnā ka hē koe mā te whakaaro he ōrite tonu, ka taea te tango i ngā miro, te kino hoki o te hononga, ā, me whakakapi anō.

Ko ngā rerekētanga matua ko te koki me te teitei o te miro. He koki 60-tohu te miro NPT, ko te koki 55-tohu ia o ngā miro BSPT. Nā tēnei rerekētanga iti nei ka kore e taea e rātou te hanga i tētahi hiri tika, mau tonu.

I te tirohanga tuatahi, kāore pea koe e kite i te rerekētanga. Engari he tino rerekē te hangarau kei muri i a rātou. E rua ngā take matua: te āhua o ngā miro takitahi me te āhua o tā rātou hiri. Ko teNPT (Whakaiti Paipa ā-Motu)Ko te paerewa e whakamahi ana i ngā miro he papatahi ngā tihi me ngā awaawa.BSPT (Paipa Paerewa o Peretānia)He porowhita te āhua o ngā miro, pērā i te āhua o Whitworth. Ko te rerekētanga tino nui ko te koki. Ko te tikanga o tēnei kore ōrite o te koki, ki te ngana koe ki te whakawiri i tētahi hononga NPT ki roto i tētahi hononga BSPT, ko ngā pito anake o ngā miro ka pā. Ka hangaia he hononga ngoikore ka turuturu i raro i te pēhanga, ā, ka ngāwari te tango. Kāore i hangaia kia mahi tahi.

NPT me BSPT: Ngā Rerekētanga Hangarau Matua

Āhuatanga	NPT (Paerewa o Amerika)	BSPT (Paerewa o Peretānia)
Koki Miro	60 nekehanga	55 nekehanga
Kōtaha Miro	Ngā tihi me ngā awaawa papatahi	Ngā tihi me ngā awaawa porowhita
Hiri Matua	Ngā miro e piri tahi ana (taper)	He hiri i runga i ngā miro
Rohe Noa	Amerika ki te Raki	Ūropi, Āhia, Ahitereiria, Ao Whānui

He pai ake te paerewa miro NPT, BSP rānei?

Me pupuri e koe te momo hononga miro pai rawa atu, tino whai hua hoki. Mēnā kāore e tika te paerewa o tō mākete, ka puhoi te neke o ngā taonga, ā, ka kore hoki e harikoa ngā kaihoko.

Kāore tetahi o ngā paerewa i te "pai ake" i tētahi atu; he rerekē noa iho. Ko te kōwhiringa pai ko te mea e paerewa ana i tō rohe ā-whenua, ā, e ōrite ana ki ngā taputapu e whakamahia ana e ō kiritaki.

He pātai tēnei mō te wāhi, ehara i te kounga. Ko te NPT te paerewa matua i te Hononga o Amerika me Kanata. Mena kei te mahi koe i tētahi kaupapa i hangaia e tētahi kamupene o Amerika, kei te whakamahi rānei i ngā taputapu o Amerika, me tino hiahia koeNgā hononga NPT. Ko te BSP ia, koia te paerewa e whakamahia ana i te nuinga o ngā wāhi o te ao, tae atu ki a Ūropi, te UK, Āhia, Ahitereiria, me Āwherika ki te Tonga. Mō te mākete a Budi i te Tonga-mā-rāwhiti o Āhia, ka taea te whakaranu. E mōhio ana ahau he maha ngā kaupapa ā-rohe me ngā kaupapa e awehia ana e Ūropi ka hiahia ki te BSPT. Heoi, ko ngā kaupapa e haumi ana, e hangarau ana rānei o Amerika, he maha ngā wā ka tohua he paerewa ANSI, arā, ko te NPT. Ko te takirere "pai rawa atu" ko te mea e tino pai ana te wiri ki roto i te paipa a tō kiritaki. Koia te mea nui kia pātai atu, kia whakaū hoki ko tēhea paerewa e hiahiatia ana mō ia kaupapa motuhake.

He mea noa ngā miro NPT i runga i ngā hononga PVC?

Kei te tono koe i ngā takirere pōro PVC, ā, me whiriwhiri koe i te momo miro. Me mōhio koe mēnā ka taea te hanga hononga kirihou me ēnei miro paipa whakarewa noa.

Ae, he mea hanga noa ngā hononga PVC me ngā miro NPT me te BSP. Mā tēnei ka taea e ngā pūnaha paipa kirihou te hono ngāwari ki ngā paipa whakarewa miro, ngā papu, me ētahi atu wāhanga paipa paerewa.

I Pntek, he whānuitanga nui o ngā hononga PVC e hangaia ana e mātou me ngā miro NPT me BSP hei mahi mā ō mātou hoa mahi o te ao. Ko te miro te huarahi paerewa hei hanga hononga ka taea te huihui me te wetewete. Heoi, he mea nui kia whakaarohia te kaha o te kirihou. Mā te tukanga tapahi miro ka tangohia te rauemi ka hangaia he pūwāhi taumahatanga. Nā konei, ka tūtohu tonu mātou kia whakamahia he pakitara matotoru ake.Rārangi 80 PVCmōhononga miro, inā koa i roto i ngā pūnaha he nui ake te pēhanga, he nui ake rānei te ahotea ā-ringa. Ahakoa ka taea e koe te miro i ngā paipa me ngā hononga Whakaritenga 40, ka tino whakaitihia te kaha o tā rātou whakahaere pēhanga. He pono ake te whakamahi i tētahi hononga PVC miro kua hangaia i te wheketere i te tapahi i ngā miro ki roto i tētahi paipa noa.

Ka taea e koe te hono i ngā miro BSPT me NPT?

He hononga NPT uwha tāu, he paipa BSPT tāne hoki kei te taha o te paipa. Te āhua nei ka piri pea, ā, ka hiahia pea koe ki te whakaoti i te mahi.

Kāo, kaua rawa e hono tika i ngā miro BSPT me NPT. Mā ngā koki kāore i te ōrite ka herea, ka whakawhiti miro, ka pakaru hoki ngā hononga. Ka puta he hononga ngoikore ka tino turuturu.

He huarahi angitu te ngana ki te whakakotahi i ēnei paerewa e rua. Nā te rerekētanga o ngā koki me ngā papa o ngā miro, kāore e taea te hono tika. Ko te mea ka tupu ko te tukanga e kiia nei ko "whakawhiti-miro," te wāhi e tapahia ai te tihi o tētahi miro ki te pūtake o tētahi atu, kaua e noho mārire. Ka pakaru tonu tēnei i ngā miro tāne me ngā miro wahine. Ahakoa he nui te rīpene hiri miro e whakamahia ana e koe, e kore e whakakīia ngā āputa i hangaia e te āhuahanga kāore i te ōrite. Ka turuturu te hononga ina pēhia te pūnaha. Ko te huarahi tika me te ngaio anake ki te hono i tētahiPūnaha BSPT ki tētahi pūnaha NPTmā te whakamahi i tētahi hononga urutau motuhake. He mea hanga ēnei urutau ki ngā miro uwha me ngā miro tāne tika i ngā pito rerekē hei hanga i tētahi whakawhiti haumaru, ātete turuturu.

Whakamutunga

He rerekē ngā paerewa NPT me BSPT, kāore e hototahi. Ko te kōwhiringa tika ka whakatauhia e te wāhi me ngā whakaritenga o tō kaupapa. Me whakaū tonu i te paerewa e hiahiatia ana kia mau ai te hononga haumaru, pono, me te kore turuturu mō ō hononga PVC.
