Ko te takirere taki pereti rua API 594 e whakamahia ana mō ngā paipa parakore me ngā paipa ahumahi, tiaki taiao, maimoatanga wai, tuku wai me te rerenga wai i roto i ngā whare teitei hei ārai i te rere whakamuri o ngā pāpāho. He momo wafer te takirere taki, e rua ngā haurua porowhita o te pereti pūrerehua, ā, he puna hei akiaki i te tautuhi anō, ko te mata hiri ka taea te whakamahi i te rauemi ātete-mau o te mata o te tinana, te arai rapa rānei, he whānui te whānuitanga o te whakamahinga, ā, he pono te hiri.

Ko ngā wāhanga whakatuwhera me te kati o te takirere tirotiro API 594 e whakawhirinaki ana ki te rere me te kaha o te reo hei whakatuwhera, hei kati rānei i a rātou anō kia kore ai e hoki mai te reo. Ka kiia te takirere ko te takirere tirotiro. Kei roto ngā takirere tirotiro i te kāwai o ngā takirere aunoa, e whakamahia nuitia ana i roto i ngā paipa e rere ana te reo i te taha kotahi, ā, ka tukuna noa te reo kia rere i te taha kotahi hei ārai i ngā aituā.

E ai ki te hanganga o te takirere tirotiro, ka taea te wehewehe kia toru ngā momo:takirere tirotiro hiki, takirere tirotiro hurihurimetakirere tirotiro angaKa taea te wehewehe i ngā takirere arataki kia rua ngā momo: poutū me te whakapae. E toru ngā momo o ngā takirere arataki hurihuri: takirere kotahi, takirere takirua me te takirere maha. He momo tika te takirere arataki wafer. He takirere arataki te takirere e ārai aunoa ana i te rere o te wai. Ka tuwhera te taupoki takirere o te takirere arataki i raro i te mahi a te pēhanga wai, ā, ka rere te wai mai i te taha tomo ki te taha putanga. Ina iti iho te pēhanga i te taha tomo i tērā i te taha putanga, ka kati aunoa te taupoki takirere i raro i te mahi a te rerekētanga pēhanga wai, te kaha ā-papa me ētahi atu āhuatanga hei ārai i te rere o te wai.

Te mōhiotanga ngaio ki ngā takirere tirotiro API 594

He aha te Paerewa API 594

Ko te API 594, i whakatūria e te American Petroleum Institute (API), koia te paerewa ahumahi whakamutunga e kīia ana ko "Check Valves: Flanged, Lug, Wafer, and Butt-welding Types." Ko tēnei whakatakotoranga nui e whakahaere ana i te hoahoa, te kōwhiringa rauemi, ngā āhuatanga hanganga, te manawanui pēhanga-pāmahana, me ngā tikanga tirotiro/whakamātautau mō ngā takirere tirotiro ahumahi.

Te Whānuitanga me te Whakamahinga o te API 594

E pā ana te API 594 ki ngā takirere tirotiro Momo A (poto kanohi ki te kanohi) me te Momo B (roa kanohi ki te kanohi). Ka kapi katoa i ngā hoahoa hanganga maha, tae atu ki:

• Ngā Takirere Tirotiro Piko
• Ngā Takirere Ārai Hiki
• Takirere Taki Pereti Takirua /Takirere Tirotiro Wafers
• Ngā Takirere Tirotiro Pūrerehua
  E pā ana te paerewa ki ngā rahi takirere mai i te DN 150 (NPS 6) ki te DN 400 (NPS 16). Ka whakahaere i ngā takirere i hangaia mai i ngā rauemi pēnei i te rino maka hina, te rino ngāwari, te maitai waro, te maitai kore waikura, me ētahi atu koranu.

Ngā Whakaritenga Hoahoa me ngā Rauemi API 594

• Te Whakatutukitanga o te Hoahoa: Me tino piri te hoahoa o te takirere ki ngā whakaritenga API 594.
• Paerewa Hononga: Me tutuki ngā hononga pito (flanged, lug, wafer, butt-weld) ki ngā ine me ngā whakatauranga kua whakarārangihia i roto i ngā paerewa kua tohua pēnei i te ASME B16.11 (Socket Welding & Threaded) me te ASME B16.15 (Cast Bronze Threaded Fittings – Class 125 me te 250).
• Kōwhiringa Rauemi: Ko ngā rauemi tinana e whakaaetia ana ko te rino maka hina, te rino ngāwari, te maitai waro, te maitai kore waikura, me ngā momo koranu. He mea nui, me hototahi te rauemi mata hiri ki te rauemi ratonga motuhake hei whakarite i te pono me te ārai i te waikura, te pirau rānei.

Hanganga me ngā Tikanga Hononga o te Takirere

E whakarōpūtia ana ngā takirere e te API 594 i runga i ō rātou hononga mutunga:

• Momo Pīra: Ka whakamahia ngā pito pīra hei hononga pūtu ki ngā pīra paipa. He pai mō ngā pūnaha paipa pīra paerewa e hiahia ana kia ngāwari te huihui/te wetewete.
• Momo Whakarewa-Pūmau: He pito whakapiko hei whakarewa tika ki te paipa. I hangaia mō ngā tono ratonga pāmahana teitei, pēhanga teitei, me ngā tono ratonga nui e tino hiahiatia ana te ārai i te turuturu.
• Momo Pūwero: Kei roto ngā whakaurunga miro (ngā pūwero) ki te tinana takirere, e taea ai te tāuta i waenga i ngā pūwero mā te whakamahi i ngā pūtu mā roto i ngā pūwero, e tika ana mō te mahi mutunga kore.
• Momo Angaanga: He hoahoa kiato, māmā hoki e tāutahia ana i waenganui i ngā āputa mā te whakamahi i ngā pūtu roa e horapa ana i te paipa katoa. He penapena wāhi mō ngā pūnaha paipa ahumahi.

Ngā Whakatauranga Pēhanga-Pāmahana

E whakamārama ana te API 594 i ngā whakatauranga pēhanga-pāmahana (PT) mō ngā takirere tirotiro i runga i te rauemi, te hoahoa, me te rahi. Mā ēnei whakatauranga ka taea e te takirere te mahi haumaru me te pono i raro i ngā āhuatanga pāmahana me te pēhanga kua tohua puta noa i tōna oranga mahi. Me piri pono ngā kaihoahoa me ngā kaiwhakahaere ki ēnei herenga PT.

Ngā Whakaritenga Tirotiro me te Whakamātautau

Ka tirotirohia, ka whakamatautauria hoki ngā takirere tirotiro API 594 katoa hei manatoko i te mahi me te pono. E whai ana ngā tikanga whakamātautau i ngā paerewa ahumahi, arā:

• API 598: Tirotiro me te Whakamātautau i te Takirere (e kapi ana i ngā whakamātautau anga, ngā whakamātautau nohoanga, ngā whakamātautau nohoanga o muri, me ētahi atu).
• ASME B16.10: Ngā Ahu Mata-ki-te-Mata me te Pito-ki-te-Pito o ngā Takirere.
  Ko ngā whakamātautau matua ko:
• Whakamātautau Kaha o te Anga: Manatoko i te pakari o te tinana me te taupoki o te waka e pupuri ana i te pēhanga.
• Whakamātautau turuturu nohoanga: Whakaū i te kaha hiri o te tikanga kati.
• Whakamātautau Katinga Pēhanga-Teitei: Ka whakarite kia hiritia i raro i te pēhanga kua whakatauria.
• Whakamātautau Katinga Pēhanga-Iti: Ka whakarite kia hiritia i raro i te pēhanga iti rawa.
• Whakamātautau Nohoanga o Muri (mēnā e tika ana): Whakamana i te hiri o te kakau i raro i te pēhanga ina tuwhera katoa te takirere.
