Kupu Whakataki
Ina titiro tātou ki te ao hou—mai i ngā whanga o ō tātou tāone nui ki ngā whatunga hiko kore e kitea e whakakaha ana i ō tātou kāinga—tērā tētahi toa wahangu e pupuri ana i te taumaha o te ahunga whakamua: te paipa rino whānui.
Heoi, i roto i te ao o te miihini taumaha, kāore i te rite te hanganga o ngā paipa katoa. Ina neke tetahi kaupapa mai i te "paerewa" ki te "tino kino" - e uru ana ki ngā pēhanga nui, ngā taiao waikura o te moana hohonu, ngā kawenga hanganga nui rānei - ka neke te umanga mai i ngā kōwhiringa whānui. Engari, ka noho te paerewa koura heiLSAW(Whakapirihia te Pewa Ruku Roa)ngā paipa, inā koa ko ērā i hangaia mā roto i te hangarau matatauJCOEtukanga.
Engari he aha te mea e wehewehe ana i te paipa JCOE mai i te ngongo porowhita noa? Ā, me pēhea te hurihanga o te pereti maitai papatahi hei oko pēhanga teitei e kaha ana ki te ora i runga i te papa moana mō ngā tau rima tekau? Ka tūhuratia e tēnei aratohu te arorau hangarau, te pakari o te hanga, me ngā paerewa mākete e tautuhi ana i tēnei hangarau maitai nui.
Te Wetewete i ngā Kupu Ahumahi
Hei mārama ki te utu nui o ēnei paipa, me mārama tātou ki ngā kupu matua o ngā pepa raraunga hangarau.
Te Mārama ki te LSAW Paipa LSAWe pā ana ki te tikanga whakarewa. He rerekē ki ngā paipa whakarewa porowhita (SSAW), he mea hanga kia rite ki te roera tauera pepa kātene me te hononga takai, he hononga tika kotahi kei roto i ngā paipa LSAW puta noa i te roanga.
Te taha hangarau:He poto ake te hononga tika i te hononga porowhita. I roto i te ao o te whakahaere kounga, ko te tikanga o te hononga poto he iti ake te "tapanga tatauranga" mō ngā hapa pea. Koia te take he kōwhiringa nui te LSAW mō te tuku hau maori e nui ana te tūponotanga.
Te Whakamārama i te JCOEHe hē noa te whakaaro he hua a JCOE; hete kanikani ā-mīhiniKo te kupu whakarāpopoto e tohu ana i te panonitanga ā-tinana e pā ana ki te maitai:
J:Te whakapiko tuatahi o ngā taha o te pereti.
C:Te piko i te haurua tuatahi o te pereti.
O:Te kati i te porowhita.
E:Ko te wāhanga "Whānui" nui e whakatau ana i te pumau o te paipa.
Te Haerenga Hanga: Mai i te Pereti ki te Tika
He tino tohunga te hanga paipa LSAW i roto i te mahi whakarewa taumaha. He tukanga tino pakari engari he tika hoki e huri ai te pereti mata hei taputapu mahi teitei.
1. Te Whakarite i te Tapa
Ka tīmata ngā mea katoa me tētahi pereti maitai taumaha. I mua i te piko, ka mirahia ngā taha ki ngā koki tika. Mā tēnei ka tino tika te "awaawa-V" mō te whakarewa hohonu ina tūtaki ngā taha e rua.
2. Te Raupapa Hanga JCO
Koinei te wāhi e uru mai ai ngā waipēhi taumaha. Ka whakamahia e te pēhi nui ngā mano tāne o te pēhanga i roto i ngā wāhanga:
Te Hanga-J:Ka piko te taha o te pereti e te mīhini pēhi, ka hanga he kōtaha "J".
Te Hanga-C:Ka hurihia, ka nekehia rānei te pereti, ā, ka pikohia te taha kē kia rite ki te taha tuatahi, ka puta he "C" tuwhera.
Te Hanga-O:Ka pēhia te pokapū ki raro, ka honoa ngā taha e rua hei hanga i te "O" kua kati.
3. Te Whakarewa Āwhata Ruku (SAW)
I te mea kua kati te hononga, ka tomo te paipa ki te teihana whakarewa. Ko te wāhanga "Rukuhia" o te ingoa e pā ana ki te paparanga o te rerenga kirikiri e tanu ana i te pewa. Ehara i te mea mō te haumaru anake tēnei; ka wehea te konganuku rewa mai i te hāora o te hau, ka ārai i ngā whakarewa pakarukaru. Ko te nuinga o ngā paipa kounga teitei ka whakarewahia kia rua ngā wā - kotahi mai i roto, kotahi mai i waho - kia mau ai te hononga 100%.
4. Te "E" – Te Whanuitanga Ā-Mīhini (Te Huringa Kēmu)
Koinei te taahiraa tino hē. Whai muri i te whakarewa, kāore te paipa i te tino porowhita, ā, kua kī tonu i te "aukati" o roto i te piko. Ka whakauruhia he whakawhanui miihini ki roto i te paipa, ka panaia ki waho. Ko tēneiwhakawhanui-makaririte maitai mā te 1% pea, ka panaia kia porowhita tino tika, ā, ko te mea nui, ka whakamama i ngā ahotea o roto. Koia te take he pai ake ngā ātete ā-ahu o ngā paipa JCOE i ō rātou hoa whakataetae.
Ngā Whakatakotoranga Hangarau me ngā Paerewa Hoko
Mō ngā miihini me ngā āpiha hokohoko, ko te "pepa whakaritenga" te Paipera Tapu. He mea hanga te hangarau JCOE mō ngā "mea nunui", ā, e whakaata ana ngā tau i tēnā.
| Āhuatanga | Pūkenga Paerewa |
| Diameter o Waho | 16″ (406mm) ki te 56″ (1422mm) |
| Matotoru o te Pakitara | 6mm ki te 40mm+ (Ka taea te whakarite mō te whakatō pou taumaha) |
| Ngā Tohu Noa | API 5L (X42 ki te X80), ASTM A252, EN 10219 |
Ngā Paninga Ora: Te "Kiri" o te Paipa
I te mea he maha ngā wā ka tanumia, ka rukuhia rānei ēnei rawa mō ngā tekau tau, he rite tonu te hiranga o te paninga ki te hiranga o te maitai.
3PE/3PP:Ko te paerewa ahumahi mō te ātete ki te waikura. Ko te 3PP (Polypropylene) te mea e pai ake ana mō ngā ihirangi pāmahana teitei.
CWC (Panihanga Taumaha Konukuraiti):Mō ngā raina raro moana. Ehara i te mea ka tiaki noa te raima; ka tāpirihia hoki te taumaha e tika ana hei pupuri i te paipa kei rere atu i te papa o te moana.
Paninga Rere ā-roto:He paparanga epoxy maeneene e whakaiti ana i te waku, ā, ka "tere ake" te paipa mō te kawe hinu me te hau.
Ngā Tono Tino Hiranga
Kei hea koe e kite ai i te LSAW? I te nuinga o te wā, i ngā wāhi ka tino pāngia koe e te turuturu, e te hinga rānei.
1.Ngā uaua pūngao pēhanga-teitei:Ina nekehia te hau pūngāwerewere i ngā pēhanga neke atu i te 10 MPa, he mea nui te pono o te hononga roa kotahi.
2.Ngā Tūāpapa Hanganga:Nā te matotoru o ngā pakitara, ko ngā paipa JCOE te whiringa tuatahi mō ngā pou piriti meNgā Monopile Hau o te Moana, me tū atu rātou i te pakipaki tonu o ngā ngaru o te moana.
3.Ngā Pūnaha Wai Matua:Ka whakamahia e ngā tāone nui te LSAW hei huarahi wai matua hei whakaiti i te mōrearea o te waipuke mai i te paipa pakaru.
Te Tirohanga ki Mua: Te Rohe Hauwai
Kei te anga whakamua te ahumahi i tēnei wāKua rite mō te hauwaingā paipa. He iti noa ngā ngota hauwai, ā, ka taea te "ngoikore" i roto i te maitai paerewa. Kei te whakamātautau kē ngā mira LSAW hou i ngā mahi whakarewa hou me ngā paninga ā-roto motuhake hei whakarite mō te whakawhiti pūngao matomato. Hei tāpiri, ko te whakaurunga o ngā hangarau e peia ana e te AIWhakamātautau Ultrasonic Aunoa (AUT)kei te waiho hei mea o mua ngā hapa a te tangata i roto i te tirotiro whakarewa.
Ngā Whakaaro Whakamutunga
Ko te paipa LSAW i hangaia e JCOE te "pū taumaha" o te ao hanganga. Ka honoa te kaha ā-tinana mata me te tika o te āhuahanga. Ahakoa he nui ake te haumitanga tuatahi i tērā o ngā paipa porowhita, ko te ROI mō te wā roa kei roto i tōna pono. I tēnei wā e hiahia ana tātou ki te hanganga kia roa ake mō te 50+ tau i raro i ngā āhuatanga taiao e piki haere ana te kino, ko JCOE tonu te whiringa tino pono a te miihini.
