Ko te kaupapa o te whakamahi i tētahitakirere tirotirohei aukati i te rere whakamuri o te reo, me tetakirere tirotiroe tāutahia ana i te putanga o te papu. Hei tāpiritanga, hetakirere tirotirokua tāutahia ki te putanga o te pūwhakakoi. I roto i te poto, hei ārai i te rere whakamuri o te reo,takirere tirotirome tāuta ki roto i ngā taputapu, ngā pūrere, ngā paipa rānei.
Ko te tikanga, ko te hiki poutūtakirere tirotiroka tīpakohia i runga i ngā paipa whakapae me te diameter ingoa o te 50mm. Hiki tika-mā rototakirere tirotiroka taea te tāuta ki ngā rārangi whakapae me ngā rārangi poutū. Ko te takirere waewae ka tāutahia noa ki te rārangi poutū o te putanga papu, ā, ka rere te wai mai i raro ki runga.
Tetakirere tirotiro hurihurika taea te hanga me te pēhanga mahi teitei, PN tae atu ki te 42MPa, ā, ka taea hoki te DN te tino nui, tae atu ki te neke atu i te 2000mm. I runga i te rauemi o te whare me ngā hiri, ka taea te whakamahi i tētahi momo mahi me tētahi awhe pāmahana whakahaere. Ko te momo he wai, he mamaoa, he hau, he momo waikura, he hinu, he kai, he rongoā, me ētahi atu. Ko te awhe pāmahana whakahaere o te momo kei waenga i te -196~800°C.
Ngā takirere tirotiro hurihurika taea te tāuta ki ngā wāhi mutunga kore, ā, he maha ngā wā ka tāutahia ki runga i ngā rārangi whakapae, engari ka taea hoki te tāuta ki runga i ngā rārangi poutū, rārangi piko rānei.
Tetakirere tirotiro pūrerehuahe pai mō te pēhanga iti me te diameter nui, ā, he iti te āhuatanga tāutanga. Nā te mea ko te pēhanga mahi o tetakirere tirotiro pūrerehuakāore e taea te tino teitei, engari ka taea te tino nui te diameter ingoa, ka taea te neke atu i te 2000mm, engari kei raro iho i te 6.4MPa te pēhanga ingoa. Ko tetakirere tirotiro pūrerehuaka taea te hanga hei momo rawhi takirua, e tāutahia ana i waenganui i ngā karapa e rua o te paipa, ā, ka tangohia te āhua o te hononga rawhi takirua.
Tetakirere tirotiro pūrerehuaka taea te tāuta ki tētahi tūranga mutunga kore, ā, ka taea hoki te tāuta ki runga i tētahi rārangi whakapae, poutū, whakarara rānei.
Diaphragmtakirere tirotirohe pai mō ngā paipa e pāngia ana e te hama wai, ā, ka taea e te diaphragm te whakakore i te hama wai ina rere te reo ki te rere. Nā te mea ko te pāmahana mahi me te pēhanga whakamahi o te diaphragmtakirere tirotirohe mea whakawhāitihia e ngā rauemi diaphragm, ā, e whakamahia whānuitia ana i roto i ngā paipa pāmahana noa iti-pēhanga, he mea tino pai mō ngā paipa wai. I te nuinga o te wā, ko te pāmahana mahi o te reo kei waenga i te -20~120°C, ā, ko te pēhanga mahi he <1.6MPa, engari ko te diaphragmtakirere tirotiroka taea te whakatutuki i tētahi kāhua nui ake, ā, ka taea e te DN te neke atu i te 2000mm.
Diaphragmtakirere tirotirokua nui ake te whakamahinga i ngā tau tata nei nā te mea he pai te mahi ā-wai, he ngāwari te hanganga, ā, he iti hoki te utu hanga.
Pōrotakirere tirotiroNā te mea he pōro te hiri kua hipokina ki te rapa, nō reira he pai te mahi hiri, he pono te mahi, ā, he pai te ātete ki te ru wai; Ā, nā te mea ka taea te hiri hei pōro kotahi, ka taea rānei te hanga hei pōro maha, nō reira ka taea te hanga hei whānui nui. Heoi, ko ōna hiri he porowhita tuwhera kua hipokina ki te rapa, kāore e pai mō ngā paipa pēhanga teitei, engari he pai mō ngā paipa pēhanga reo me te iti.
Mai i te rauemi o te whare o te pōrotakirere tirotiroka taea te hanga ki te kowiri tira, ā, ka taea te pani i te pōro tuwhera o te hiri ki te kirihou hangarau PTFE, ka taea hoki te whakamahi i roto i te paipa o ngā pāpāho waikura whānui.
Ko te pāmahana mahi o tēnei momo takirere tirotiro kei waenganui i te -101~150°C, ko tōna pēhanga ingoa he ≤4.0MPa, ā, ko te awhe whānui ingoa kei waenganui i te 200~1200mm.
