WHAKATAKI WHAKAPĀNGA

Ngā Whakatakotoranga Ā-tinana
Ko te mea tuatahi, me uru te flange ki te paipa, ki ngā taputapu rānei i hangaia ai. Ko ngā whakatakotoranga ā-tinana mō ngā flange paipa ko ngā ine me ngā āhua hoahoa.

Ngā Ahu o te Flange
Me tohu ngā āhuatanga ā-tinana kia tika ai te rahi o ngā flange.

Ko te whānui o waho (OD) te tawhiti i waenganui i ngā taha e rua e rerekē ana o te mata o te flange.
Ko te matotoru e pā ana ki te matotoru o te awhi o waho e piri ana, ā, kāore e uru te wāhanga o te flange e pupuri ana i te paipa.
Ko te whānui o te porowhita pūtu ko te roa mai i waenganui o te kōhao pūtu ki waenganui o te kōhao o tera taha.
Ko te rahi o te paipa ko te rahi o te paipa e rite ana ki te flange paipa, e hangaia ana i runga i ngā paerewa kua whakaaetia. E rua ngā tau kore-ahu e tohua ana, arā, te rahi paipa ingoa (NPS) me te rārangi (SCH).
Ko te rahi o te pū ko te diameter o roto o te hononga flange. I te wā e hanga ana, e tono ana hoki i tētahi momo hononga paipa, he mea nui kia taurite te rahi o te pū o te wahi ki te rahi o te pū o te paipa honohono.
Ngā Mata Flange
Ka taea te hanga i ngā mata o te flange kia rite ki te maha o ngā āhua ritenga i runga i ngā whakaritenga hoahoa. Ko ētahi tauira ko:

Papatahi
Mata whakaara (RF)
Hononga momo mowhiti (RTJ)
Awaawa O-mowhiti
Ngā momo o ngā flanges paipa
E waru ngā momo o ngā flange paipa, i runga i te hoahoa. Ko ēnei momo he matapo, he hononga piko, he kōhao, he whakaiti, he paheke, he hononga kōhao, he miro, me te kaki whakarewa.

He pereti porowhita ngā āputa matapo, kāore he pupuri i waenganui, e whakamahia ana hei kati i ngā pito o ngā paipa, ngā takirere, ngā taputapu rānei. Ka āwhina i te ngāwari o te urunga atu ki te raina ina oti te hiri. Ka taea hoki te whakamahi mō te whakamātautau i te pēhanga rere. He mea hanga ngā āputa matapo kia uru ki ngā paipa paerewa o ngā rahi katoa me ngā whakatauranga pēhanga teitei ake i ētahi atu momo āputa.

Ka whakamahia ngā hononga whakarara ki ngā paipa kua honoa ki ngā paipa kua whakarara, ki ngā pito rānei o ngā hononga whakarara. Ka taea e rātou te huri huri noa i te paipa kia ngāwari ai te whakarite me te huihui i ngā kōhao pūtu ahakoa kua oti ngā whakarewa. Nā tēnei painga, ka whakamahia ngā hononga whakarara ki ngā pūnaha e hiahia ana kia wetewetehia pinepine ngā hononga me te paipa. He rite ki ngā hononga paheke, engari he porowhita piko kei te poka me te mata hei whakauru i te pito o ngā hononga whakarara. He iti ngā whakatauranga pēhanga mō ngā hononga whakarara, engari he teitei ake i ngā hononga paheke.

He mea hanga ngā flange paheke-ake kia paheke ki runga i te pito o ngā paipa, kātahi ka whakarewahia ki te wāhi tika. He māmā te tāutanga, he iti te utu, ā, he pai hoki mō ngā tono pēhanga iti.

He pai rawa ngā āputa whakarewa tūhono mō ngā paipa iti, pēhanga teitei. He rite tonu te hanga ki ngā āputa paheke, engari mā te hoahoa pute o roto ka taea te whakaputa i te paipa maeneene me te rere pai ake o te wai. Ina whakarewahia ki roto, he 50% te kaha ngenge o ēnei āputa i ngā āputa paheke takirua kua whakarewahia.

Ko ngā āpiti miro he momo āpiti paipa motuhake ka taea te tāpiri ki te paipa me te kore e whakarewa. Ka mirohia ki roto i te poka kia rite ki te miro o waho o te paipa, ā, ka whakawhāitihia hei hanga hiri i waenganui i te āpiti me te paipa. Ka taea hoki te whakamahi i ngā whakarewa hiri me ngā hononga miro hei whakapakari me te hiri. He pai ake te whakamahi mō ngā paipa iti me ngā pēhanga iti, ā, me karo i ngā tono he nui ngā kawenga me ngā taipana teitei.

He pū roa, he pū whakarara hoki ngā parirau whakakoi, ā, e whakamahia ana mō ngā mahi pēhanga teitei. Ka whakawhiti te pū whakarara i te ahotea mai i te parirau ki te paipa tonu, ā, ka whakarato i te kaha hei ārai i te pakaru.
