Ngā Pātai Auau (FAQ) – Takirere Kēti Cryogenic (-196°C)
P: He aha te rerekētanga i waenga i te takirere keti cryogenic me te takirere keti paerewa?
A: He maha ngā āhuatanga matua o ngā takirere keti cryogenic kāore i kitea i roto i ngā takirere paerewa: he taupoki roa me te pereti maturuturu hei tiaki i ngā hiri kakau; he maimoatanga cryogenic hohonu o ngā wāhanga katoa; he mata hiri keti me te nohoanga Stellite mārō mō te ātete ki te kakahu; he rauemi motuhake mō te pakari pāmahana iti; he iti te tākai tukunga rerenga; me te whakamātautau mahi cryogenic whakahau e ai ki te BS 6364. Ko ngā takirere keti paerewa he taupoki kore-toronga, he mata hiri kore-mārō, ā, kāore he whakamātautau cryogenic.
Q: He aha te pāmahana ratonga iti rawa mō āu takirere keti cryogenic?
A: Ko ā mātou takirere keti cryogenic paerewa he mea whakatau mō te ratonga -196°C (pāmahana hauota wai) e ai ki te BS 6364. Mō te ratonga hauwai wai (-253°C) te ratonga herium wai rānei (-269°C), ka tukuna e mātou he hoahoa motuhake me ngā rauemi me ngā hiri kua whakarerekētia.
P: He aha te maimoatanga cryogenic hōhonu, ā, he aha i hiahiatia ai?
A: Ko te maimoatanga hohonu o te cryogenic ko te tukanga whakamatao i ngā wāhanga takirere ki te -196°C mō te iti rawa o te 8 hāora. Ka hurihia e tēnei te austenite e puritia ana, ka whakaiti i ngā ahotea toenga, ā, ka whakarite i te pumau o ngā āhuatanga i te pāmahana ratonga. E hiahiatia ana e te BS 6364 te maimoatanga hohonu o te cryogenic mō ngā takirere me ngā pāmahana ratonga ≤ -101°C.
P: He aha te Stellite hardfacing, ā, he aha i whakamahia ai?
A: Ko te whakamaroke Stellite he whakamahinga o te koranu cobalt-chromium ātete-kakahu (Stellite 6, 21 rānei) ki ngā mata hiri o te kuaha me te nohoanga. He pai rawa atu tēnei ātete kakahu, ka ārai i te whakapataritari me te hopu i ngā pāmahana cryogenic, ā, ka roa ake te roa o te mahi takirere. Ko te whakamaroke Stellite he āhuatanga paerewa o ngā takirere kuaha cryogenic e ai ki te API 600.
P: He aha te rerekētanga i waenga i ngā hoahoa kuaha poro me ngā kuaha reti whakarara?
A: Ko ngā takirere keti poro (poro totoka, poro ngāwari rānei) e whakamahia ana mō ngā rahi tae atu ki te 24 inihi, ā, he tino pai te mahi kati. Ko ngā takirere keti reti whakarara (nohoanga mānu) e whakamahia ana mō ngā rahi nui ake (≥ 12 inihi), ā, ka whakaiti i te taipana whakahaere me te pupuri tonu i te mahi hiri pai rawa atu i roto i ngā tono huringa wera.
P: He mea whakahau te whakamātautau mahi cryogenic?
A: E ai ki te BS 6364 me te MSS SP-134, he mea whakahau te whakamātautau mahi cryogenic mō ngā takirere e whakamahia ana i roto i te LNG me te ratonga cryogenic. Me mahi ngā whakamātautau i te -196°C (hauota wai) me te whakamātautau nohoanga hau pēhanga iti i muri i te whakaū i te pāmahana. Ka whakahaerehia e Womic te whakamātautau mahi cryogenic 100% i runga i ia takirere kuaha cryogenic i mua i te tukunga.

Kua whakaaetia te momo ABS me te DNV.
Ngā Wero Hangarau me ngā Otinga:
1. Ngā takirere poka nui (30 inihi) mō te raina utanga matua o te kawe LNG– E hiahiatia ana ngā takirere keti reti whakarara 30" mō te wehewehe i te tāke utanga kawe LNG. Nā te rahi nui i hiahiatia he mīhini me te huihuinga motuhake. I whakaratohia e Womic ngā takirere keti reti whakarara e whakahaerehia ana e ngā taputapu me ngā nohoanga mānu mō te huringa wera. I paahitia e ngā takirere e 4 te whakamātautau cryogenic i te -162°C me te kore turuturu.
2. He mata pakari Stellite mō te roa o te ora mahi– Ka whakamahia pinepine ngā takirere kawe LNG (te whakatuwheratanga/te kati mō ia huringa uta/te tango). I tukuna mai e Womic he mata kēti me te nohoanga Stellite 6 mārō mō ngā takirere 132 katoa. Matotoru o te mata mārō: 2.0mm i muri i te miihini. Mārō: HRC 38-45.
3. Whakaaetanga momo rōpū akomanga (ABS me DNV)– Me whai whakaaetanga momo ABS me DNV ngā takirere kawe LNG e ai ki te IGC Code (International Gas Carrier Code). Ka mahi tahi a Womic me ngā kairūri ABS me DNV mō ngā whakamātautau whakaaetanga momo tae atu ki te mahi cryogenic, te hydrostatic, me ngā whakamātautau tukunga rerenga. Ka tukuna ngā tiwhikete whakaaetanga momo i roto i ngā rā 60.
4. Maimoatanga cryogenic hōhonu mō ngā whakarewanga nunui (tinana 30 inihi)– Ngā whakarewa CF3M nunui (tinana 30") e ngawari ana ki te pupuri i te austenite. I whakahaerehia e Womic te maimoatanga cryogenic hohonu e toru-huringa (te rumaki ki te -196°C, 12 hāora ia huringa). I te tirotiro anō i ngā āhuatanga, i whakaūtia kāore he hapa i muri i te maimoatanga.
5. Te iti o te tākai tukunga rerenga mō te tutuki i ngā whakaritenga taiao– Kei te whakahaerehia ngā kawe LNG i ngā wāhi tairongo taiao e hiahia ana kia tutuki i te ISO 15848-1 Class B te tākai. I whakaratohia e Womic he tākai karāhe iti te tukunga rerenga me te hoahoa potae roa e whakarite ana kia noho tonu te pāmahana tākai ki runga ake i te -20°C.
6. I kite te kairūri whenua ABS me DNV i ngā whakamātautau– E hiahiatia ana ngā takirere 132 katoa, ā, i kite te kairūri ABS me te DNV i ngā whakamātautau i te whare o Womic. I whakaritea e Womic te kaupapa whakamātautau me ngā rōpū whakarōpū e rua. I oti te whakamātautau i roto i ngā rā 30. Kāore e hiahiatia he whakamātautau anō.
7. Tukunga tika i te wā tika mō te kaupapa hanga kaipuke LNG– I hiahiatia he tuku ā-wāhanga mō te marama e waru i roto i te maramataka hanga kaipuke LNG. I tukuna e Womic ngā takirere 132 katoa i roto i ngā tuku e ono, ā, i tae mai ia tuku i te rā i whakaritea. Kāore he whakaroa i te maramataka hanga.
Hua:I angitu te tukunga o te kaikawe LNG ki te rangatira i te tau 2023. Kua neke atu i te 2 tau te mahi a ngā takirere keti cryogenic katoa e 132 i te -162°C, kāore he aituā tiaki. I kī te kaiwhakahaere o te rangatira: "I mahi pai ngā takirere keti cryogenic a Womic i ngā whakamātautau hau – kāore he turuturu i tutuki i a mātou i ngā takirere wehe tāke utanga katoa." I tukuna e te kiritaki he whakaaetanga anga mō ētahi atu kaikawe LNG e 6.
