Kua tono koe i tētahi taraka kī tonu i ngā takirere mō tētahi kaupapa nui. Engari i te taenga mai, kāore ngā miro e ōrite ki ō paipa, ā, ka nui te whakaroa me te utu nui mō ngā whakahokinga mai.

Ko ngā momo miro matua e rua o te takirere pōro ko te NPT (National Pipe Taper) e whakamahia ana i Amerika Te Raki, me te BSP (British Standard Pipe), e kitea whānuitia ana i ngā wāhi katoa. Ko te mōhio ko tēhea te mea e whakamahia ana e tō rohe ko te taahiraa tuatahi ki te hononga ātete-tauraki.

Ko te tika o te momo miro tētahi o ngā wāhanga tino taketake, engari he mea nui, o te rapu rauemi. I mahi tahi ahau me Budi, he kaiwhakahaere hoko i Indonesia, i tono pōhēhē i tētahi ipu takirere me ngā miro NPT hei utu mō tePaerewa BSPi whakamahia i tōna whenua. He hapa noa iho i tino pāngia ai te mahunga. He rite tonu te āhua o ngā miro, engari kāore e hototahi, ā, ka turuturu. Haunga ngā miro, kei reira ētahi atu momo hononga pērā i te pūtu me te flange e whakaoti rapanga rerekē. Kia tino mohio tātou ka taea e koe te wehewehe i a rātou katoa.

He aha te tikanga o te NPT i runga i te takirere pōro?

Ka kite koe i te "NPT" i runga i tētahi pepa whakaritenga, ā, ka whakaaro koe he miro paerewa noa iho. Mēnā ka kore e aro ki tēnei taipitopito, ka puta pea he hononga e ahua piri ana engari e turuturu ana i raro i te pēhanga.

Ngā tūnga NPTmō te National Pipe Taper. Ko te kupu matua ko te "taper." He paku koki ngā miro, nō reira ka piri tahi ina whakakīia hei hanga i tētahi hiri miihini kaha.

Ko te hoahoa whakarara te mea ngaro kei muri i te kaha hiri o te NPT. I te mea he paipa NPT tāne e mirohia ana ki roto i te hononga NPT uwha, ka rerekē te whānui o ngā wāhanga e rua. Ka kuruhia ngā miro e tēnei hononga pokanoa, ka hanga te hiri tuatahi. Heoi, kāore i te tino tika tēnei whakarerekētanga whakarewa-ki-te-whakarewa, kirihou-ki-te-kirihou rānei. He iti tonu ngā āputa porowhita e toe ana. Koia te take me whakamahi tonu koe i te hiri miro, pērā i te rīpene PTFE, i te paipa rānei, me ngā hononga NPT. Ka whakakīia e te hiri ēnei āputa moroiti kia kore ai e turuturu te hononga. He paerewa matua tēnei i te United States me Canada. Mō ngā kaihoko o te ao pērā i a Budi, he mea nui kia tohua te "NPT" ina tino mohio rātou e hiahiatia ana e tā rātou kaupapa; ki te kore, me whai paerewa BSP noa i Āhia me Ūropi.

He aha ngā momo hononga takirere rerekē?

Me hono e koe tētahi takirere ki tētahi paipa. Engari ka kite koe i ngā kōwhiringa mō te "miro", "kōtui", me te "flanged", ā, kāore koe i te tino mōhio ko tēhea te mea tika mō tāu mahi.

Ko ngā momo hononga takirere matua e toru he miro mō ngā paipa wiri, he pūnga mō ngā paipa PVC piri, ā, he flanged mō ngā pūnaha paipa nui, he pūtu. He rerekē te hanga o ia momo hononga mō ngā rauemi paipa, te rahi, me te hiahia tiaki.

He rite tonu te hiranga o te whiriwhiri i te momo hononga tika ki te whiriwhiri i te takirere tika. Kāore e taea te whakawhiti. He rerekē te mahi a ia takirere, ā, he pai mō ngā whakamahinga rerekē. Whakaarohia he momo huarahi rerekē hei hono i te rori.Ngā hononga mirohe rite ki te whakawhitinga paerewa,ngā hononga pūokoHe rite ki te hononga tuturu, e honoa ai ngā rori e rua ki te kotahi, ā, he rite ngā hononga flanged ki te wāhanga piriti modular ka taea te whakawhiti ngāwari. Ka tohutohu tonu ahau i te tīma a Budi kia ārahi i ā rātou kiritaki i runga i te heke mai o tā rātou pūnaha. He raina whakamakuku tuturu e kore e whakarerekētia? Whakamahia he hononga kōhao. He hononga ki te papu me whakakapi pea? Whakamahia he takirere miro, he takirere flanged rānei kia ngāwari ai te tango.

Ngā Momo Hononga Takirere Matua

He aha ngā momo takirere pōro e whā?

Ka rongo koe i te iwi e kōrero ana mō ngā takirere "kotahi-wahi", "rua-wahi", "toru-wahi" rānei. He ahua pōhēhē tēnei, ā, e manukanuka ana koe kei te hoko koe i te mea hē mō tō tahua me ngā hiahia tiaki.

He maha ngā wā ka whakarōpūtia ngā takirere pōro e ai ki te hanganga o tō rātou tinana: Kotahi-Wāhanga (Kiti rānei), Rua-Wāhanga, me Toru-Wāhanga. Mā ēnei hoahoa ka whakatau te utu o te takirere me te mea ka taea te whakatika.

Ahakoa e whakahuatia ana e te tangata ētahi momo e whā, ko ngā momo hanga matua e toru e kapi ana i te nuinga o ngā tono.Takirere "Kotahi-Wāhanga", e kiia ana he takirere iti, he tinana i hangaia mai i te kirihou kotahi i hangaia. He hiri kei roto o te pōro, nō reira kāore e taea te wetewete mō ngā whakatikatika. Nā tēnei ka waiho ko te kōwhiringa iti rawa te utu, engari he mea tuku noa iho. Ko te tinana o te takirere "Wāhanga-Rua" he tinana i hangaia mai i ngā wāhanga e rua e wiri ana i te pōro. Koinei te momo tino noa. Ka taea te tango mai i te paipa me te wetewete hei whakakapi i ngā hiri o roto, e tuku ana i te taurite pai o te utu me te ngāwari o te mahi. Ko te takirere "Wāhanga-Toru" te mea tino matatau. He tinana pokapū kei roto te pōro, me ngā hononga pito motuhake e rua. Mā tēnei hoahoa ka taea e koe te tango i te tinana matua mō te whakatikatika, te whakakapi rānei me te kore e tapahi i te paipa. Ko te mea tino utu nui engari he pai mō ngā raina wheketere kāore e taea e koe te utu mō te kati roa mō te tiaki.

He aha te rerekētanga i waenga i te hononga NPT me te hononga flange?

Kei te hoahoa koe i tētahi pūnaha, ā, me whiriwhiri koe i waenga i ngā takirere miro, i ngā takirere pūwero rānei. Mēnā ka hē te whiriwhiri, ka uaua te tāutanga, ā, ka nui ake te utu o te tiaki ā muri ake nei.

He miro ngā hononga NPT, ā, he pai rawa atu mō ngā paipa iti ake, ka hangaia he hononga pumau, he uaua ake te tiaki. Ka whakamahia e ngā hononga flange he pūtu, ā, he pai rawa atu mō ngā paipa nunui ake, kia māmā ai te tango i te takirere mō te tiaki.

Ko te kōwhiringa i waenga i te NPT me te flange e ahu mai ana i ngā mea e toru: te rahi o te paipa, te pēhanga, me ngā hiahia tiaki. He tino pai ngā miro NPT mō ngā paipa iti ake te diameter, ko te nuinga he 4 inihi te whānui me raro iho. He iti te utu, ā, ka hangaia he hiri kaha, he pēhanga teitei ina tāuta tika me te hiri. Ko tō rātou ngoikoretanga nui ko te tiaki. Hei whakakapi i te takirere miro, me tapahi pinepine te paipa. Ko ngā flange te otinga mō ngā paipa nui ake me ngā pūnaha katoa e matua ana te tiaki. Mā te whakapiri i te takirere i waenga i ngā flange e rua ka taea te tango me te whakakapi wawe me te kore e whakararuraru i ngā paipa. Koinei te take e tono ana ngā kiritaki kirimana a Budi e hanga ana i ngā tipu maimoatanga wai nui i ngā takirere flange. He nui ake te utu i mua, engari ka penapenahia he nui te wā me te mahi i ngā whakatikatika a meake nei.

Whakataurite NPT me te Flange

Whakamutunga

Ko te whiriwhiri i te miro tika, i te hononga tika rānei—NPT, BSP, kōpuku, flange rānei—koinei te taahiraa tino nui mō te hanga i tētahi pūnaha haumaru, ā-kore turuturu, me te whakarite kia ngāwari te tiaki a meake nei.
