1. Te Whakamāramatanga me te Hanganga Taketake
Ko te takirere pūrerehua porowhita hiri ngohengohe (e mōhiotia ana ko te "takirere pūrerehua raina-pokapū") he takirere hurihuri hauwhā-hurihanga i hangaia hei whakakā/whakaweto, hei whakawhāiti rānei i te rere o te rere i roto i ngā paipa. Ko ōna āhuatanga matua ko:
Hoahoa Pūtahi: Kei te tūhonohono te kakau takirere, te kōpae, me te nohoanga ki te tuaka pokapū kotahi, ka hangaia he hanganga māmā, kiato hoki.
Tikanga Hiri Ngāwari: Kua whakauruhia he hiri elastomeric ngāwari (hei tauira, te rapa, EPDM, NBR) ki roto i te tinana takirere, i te nohoanga rānei, hei whakarato i te hiri piri hei ārai i te turuturu.
Ngā Pito Whakapiripiri: He hononga whakapiripiri kei te takirere, e māmā ai te tāutanga ki ngā paipa e tutuki ana i ngā paerewa pēnei i te ANSI, DIN, JIS rānei.
2.Ngā Wāhanga Matua
3. Te Mātāpono Mahi
Tūnga Tuwhera: Ka huri te kōpae i te 90° kia hāngai ki te ahunga o te rere, kia whakaitihia ai te hekenga pehanga, kia pai ai te rere katoa.
Tūnga Katia: Ka huri whakamuri te kōpae ki te pēhi i te hiri ngohengohe, ka hanga he kati piri. Ko te hoahoa porowhita e whakawhirinaki ana ki te whakarerekētanga ngāwari o te hiri hei whakatutuki i te hiri, kia tino whai hua ai mō ngā tono pēhanga iti.
4. Ngā Āhuatanga Matua me ngā Painga
Hiritanga Pūmau: He tino pai te ātete o ngā hiri ngohengohe ki te turuturu, ā, he maha ngā wā ka tutuki i ngā paerewa pūmau-mirumiru (hei tauira, ANSI B16.104 Akomanga VI, ISO 15848-1).
Te Mahi Taipana Iti: Ka whakaitihia e te hoahoa porowhita me te hiri ngāwari te waku, ka taea ai te whakahaere ā-ringa, te whakamahi rānei me ngā kaiwhakaoho mama.
Kiato, Mama hoki: Ki te whakaritea ki ngā takirere kuaha, ki ngā takirere porowhita rānei, he iti ake ngā takirere pūrerehua porowhita, ā, he māmā ake te tāuta ki ngā wāhi iti.
Utu-whai hua: Nā te ngāwari o te hanganga me te iti o te whakamahinga rauemi, he iti te utu mō ngā hiahia whakahaere rere taketake.
Hototahi ki ngā Pāpāho Maha-ā-ringa: He pai mō te wai, te hau, te hinu, ngā wai kore-waikura, me ngā pāpāho kirikiri (me ngā paninga ātete-pakura).
5. Ngā Whakatakotoranga Hangarau
Whakatauranga Pēhanga: Te pēhanga iti ki te pēhanga waenga (hei tauira, PN6–PN16 / Akomanga 125–Akomanga 150).
Awhe Pāmahana:
Ngā elastomer paerewa (hei tauira, NR, EPDM): -10°C ki te 90°C (14°F ki te 194°F).
Ngā hiri pāmahana teitei (hei tauira, Viton®, PTFE): -20°C ki te 150°C (-4°F ki te 302°F).
Te Whakatutukitanga Paerewa:
Hoahoa: EN593, API 609, MSS SP-67.
Flange: ANSI B16.5, ANSI B16.10 DIN EN 1092-1,
Whakamātautau: API 598, (ngā whakamātautau turuturu).
6. Ngā tono
Ngā takirere pūrerehua porowhita hiri ngohengohe D341X-16Qe whakamahia whānuitia ana i roto i:
Te Tuku Wai me te Waikeri: Ngā pūnaha wai ā-tāone, ngā whare rongoā parakaingaki, me ngā whatunga whakamakuku.
Ngā Pūnaha HVAC: Te whakahaere i te hau, te wai, te mamaoa rānei i roto i te whakamahana, te whakapūhautanga, me te hauhautanga.
Ahumahi Kai me te Inu: Ngā tono hauora me ngā hiri e tutuki ana i ngā whakaritenga a te FDA (hei tauira, EPDM me ngā paninga kounga kai).
Ngā Tukanga Ahumahi Whānui: Te whakahaere i ngā wai kore-waikura i roto i ngā tipu matū, pepa, me ngā tipu rongoā (mō ngā rauemi ngawari anake).
Te Moana me te Hanga kaipuke: Te mana whakaweto/whakakā i roto i ngā pūnaha wai moana, i ngā pūnaha taumaha rānei (me ngā rauemi ātete-waikura).
7. Ngā Here me ngā Whakaaroaro
Ngā Herenga Pēhanga me te Pāmahana: Kāore e tika mō ngā tono pēhanga teitei (hei tauira, >PN16) me ngā tono pāmahana tino nui (hei tauira, te mamaoa i runga ake i te 150°C).
Ngā Mōrearea o te Waikura: Ka waikura pea ngā wāhanga whakarewa (hei tauira, ngā tinana rino maka) i ngā taiao kino; whakapai ake ki te maitai kore waikura, ki ngā rauemi pania rānei mō ngā āhuatanga kino.
Ngā Pāpāho Whakarara: Ka tere te pakaru o ngā hiri ngohengohe nā ngā wai e ki ana i ngā matūriki; whakaarohia ngā takirere pūrerehua hiri-mārō, ngā paninga tiaki tāpiri rānei.
Kōwhiringa Pūwhakaoho: Mō ngā takirere whānui, mō ngā mahi auau rānei, whakamahia ngā pūwhakaoho hau/waipēhi hei karo i te ngenge ā-ringa.
8. Te Tāutanga me te Tiaki
Tāutanga:
Me whakarite kia ōrite te tūnga o ngā flange, kia rite hoki te whakau o ngā pūtu hei ārai i te turuturu.
Āta tirohia te tāutanga o te takirere i raro i te taumahatanga nui rawa o te paipa.
Te Tiaki:
Tirohia te hiri i ia wā, mō te pakaru, te ngatata rānei, inā koa i ngā whakamahinga huringa teitei.
Me pania te kakau me te actuator ki te hinu i ia wā kia maeneene ai te mahi.
Whakakapia te hiri mēnā ka turuturu; i ētahi hoahoa ka taea te whakakapi i te hiri me te kore e tangohia te takirere mai i te paipa.
9Ngā Tohutohu mō te Kōwhiringa a te Kaiwhakarato me te Hua
Tiwhikete Rauemi: Me whakarite kia tutuki ngā paerewa ahumahi i ngā hiri (hei tauira, te FDA mō te kai, te ATEX mō ngā taiao pahū).
Ngā Kōwhiringa Whakaritenga: Ka tukuna e ētahi kaiwhakarato ngā hoahoa ārai-pūmau, ngā āhuatanga haumaru-ahi, ngā paninga motuhake rānei (hei tauira, epoxy, PTFE) mō ngā tono motuhake.
Whakamutunga
Ngā takirere pūrerehua porowhita hiri ngohengoheHe otinga pono, he iti te utu, he iti te pēhanga i roto i ngā tono kore-tino nui. Nā te ngāwari, te hiri piri, me te ngāwari o te tiaki, he mea rongonui ēnei i roto i te wai, te HVAC, me ngā pūnaha ahumahi whānui. Mō ngā taiao uaua ake, e taunakihia ana kia whakapai ake ki ngā hoahoa rerekē, ki ngā rauemi kounga teitei rānei. Arotakehia tonutia ngā āhuatanga pāpāho, ngā tikanga whakahaere, me ngā whakaritenga tutuki hei whiriwhiri i te takirere tino pai mō ō hiahia.
