1. He aha i whiriwhiri ai koe i tētahi paipa whakakikoruatia – ā, he aha i whiriwhiri ai koe i te maitai Womic hei kaihanga māu?
Ka whakakotahihia e te paipa whakakikoruatia hepaparanga o waho o te maitai waro kaha teitei, te maitai koranu iti rānei(e whakahaere ana i te pēhanga, te kawenga ā-mīhini, me te utu) me tepaparanga o roto o te koranu ātete waikura(e pā tika ana ki ngā wai kaha). Ka whakaitihia e tēnei hanganga paparanga-rua te utu rauemi mā te 30–60% ki te whakaritea ki te paipa CRA totoka, me te whakarato i te parenga waikura me te roa o te mahi.
Heikaihanga paipa whakakikoruatia, Kāore a Womic Steel e tuku noa i tētahi rārangi rauemi. Ka tīmata mātou me ngā āhuatanga o tō tukanga: H₂S, CO₂, Cl⁻, pH, pāmahana, pēhanga, pēhanga wāhanga hauwai, me ngā whakaritenga ā-mīhini. Kātahi ka tūtohu mātou i te huinga tino pono me te ohanga o te maitai tautoko, te whakakikorua CRA, me te tukanga here.
I ahu mai ō mātou wheako i ngā kaupapa tūturu – ngā mara hau kawa o uta, ngā hononga here o raro moana hohonu, ngā kohua hiko tino-tino-tino, ngā raina pairati hauwai, me ngā pūnaha werohanga CCUS-EOR. E mārama ana mātou ehara te paipa whakakikoruatia i te taonga hokohoko; he hua hangarau.
2. Ngā Tukanga Whakakikorua – Te Hononga o ngā Konganuku e Rua
Ko te mea nui ki tētahi paipa whakakikoruatia pono ko tetikanga herei waenganui i te maitai tautoko me te paparanga CRA. Kei raro nei ngā tukanga matua e whā e whakamahia ana e mātou, e whakarōpūtia ana e te kaha o te here me te pai o te tono.
2.1 Te Makahanga Pūwero + Te Tangohanga Wera (Here Whakarewa Kore Tuitui)
Te āhua o tana mahi:
Ka makahia te paparanga CRA mā te porotītaha ki roto i tētahi ngongo tuwhera. Kātahi ka whakaurua tēnei ngongo ki roto i tētahi pire maitai waro, ka whakamahanahia, ka tukuna ngātahitia mā roto i tētahi mīhini pēhi nui. I te pāmahana me te pēhanga teitei, ka horapa ngā konganuku e rua ki roto i a rātou anō, ka hanga he hononga whakarewa tūturu.
Ngā āhuatanga here:
● Kaha kutikuti atanga ≥300 MPa (teitei rawa atu i roto i ngā tukanga katoa)
● Kāore he hononga whakarewa roa – tino kore hononga
● Te matotoru o te uhi, ngā inenga tika
Tino pai mō:
Ngā diameter iti ki te rahi (≤400mm – ~16″), te pēhanga teitei, te huringa wera nui, te ratonga hauwai, ngā ngongo poiha, ngā ngongo o raro, ngā piko-U o te whakawhiti wera.
2.2 Te Hononga Rōra Wera + Te Hanga JCOE / UOE
Te āhua o tana mahi:
Ka horoia te pereti CRA me te pereti maitai waro, ka whakatakotoria ki roto i te korehau, ka hiritia, ka whakamahanatia, ka tukuna mā roto i te mira hurihuri. Ka hangaia he hononga whakarewa mā te maha o ngā hurihanga. Kātahi ka hangaia te pereti kua whakakikoruatia hei paipa mā te whakamahi i te JCOE (JCO-Edge) me te UOE rānei, ā, ka whai ake ko te whakarewa hononga roa.
Ngā āhuatanga here:
● Kaha kutikuti atanga 200–260 MPa
● Ka taea ngā diameter tino nui (tae atu ki te 1,800mm / 72″)
● Ngā roa takitahi (tae atu ki te 24m, neke atu rānei)
● Kei roto ko te hononga whakarewa roa kotahi (me whai tohu me te tirotiro NDT)
Tino pai mō:
Ngā paipa tawhiti roa, ngā paipa wai hohonu, ngā paipa pūtake, ngā paipa whakaara. Koinei te tukanga e whakamahia whānuitia ana mō ngā paipa raina kua whakakikoruatia ki te API 5LD.
2.3 Te Whakatakotoranga Pāhū + Te Hurihuri Pereti
Te āhua o tana mahi:
Ka whakatakotoria he pereti CRA ki runga i tētahi pereti maitai waro kua whakaritea he āputa, kātahi ka hipokina ki ngā mea pahū. Ka panaia te pereti CRA e te pahūtanga ki roto i te pereti tuara i te tere teitei, ka hanga he hononga ngaru, he rite ki te konganuku. Kātahi ka hurihia te pereti kua whakakikoruatia, ka whakarewaina ki roto i te paipa.
Ngā āhuatanga here:
● Atanga ngaru me te kaha hononga tino pai (200–280 MPa)
● Ka taea te hono i ngā konganuku rerekē e uaua ana ki te hurihuri (hei tauira, te titanium ki te maitai, te zirconium ki te maitai)
● He iti te rahi o te pereti nā te kaha pahū; me whai hononga whakarewa i muri mai
Tino pai mō:
Ngā huinga whakakikorua tauhou: titanium/maitai, zirconium/maitai, tantalum/maitai mō ngā paipa me ngā whakawhiti wera o te tipu matū tino kaha.
2.4 Whakatakotoranga Ā-ringa (Kāore i te Manakohia mō ngā Ratonga Tino Hira)
Te āhua o tana mahi:
Ka whakawhanuitia te ngongo arai CRA mā te matao, mā te waipēhi rānei i roto i te paipa maitai waro. Ka noho tahi ngā paparanga e rua mā te taunga pokanoa (te ahotea porowhita).
Ngā āhuatanga here:
●Kāore he here whakarewa– te whakapā tinana anake
● Kaha here <10 MPa
● Ka taea e te arai te miro, te hinga, te wetewete rānei i raro i te huringa wera, i te pēhanga rānei
Ina whakamahia e mātou:
Mō ngā ratonga pāmahana iti, pēhanga iti, kore-hurihuri, kore-wiri anake, ā, mēnā ka whakaae mārama te kiritaki ki ngā herenga. Ka whakamārama tonu mātou i ngā mōrearea ki te whakataurite ki ngā paipa kua whakakikoruatia ki te konganuku.
Tā mātou taunakitanga:Mō ngā ratonga hinu me te hau, hauwai, wai hohonu rānei, whiriwhiria he paipa kua whakakikoruatia ki te konganuku – kaua ki te paipa kua whakakikoruatia ki te mīhini.

P1: He aha te rerekētanga tūturu i waenga i te paipa kua whakakikoruatia ki te konganuku me te paipa kua whakakikoruatia ki te miihini?
A: He paparanga horapa taumata-atomika tō te paipa here whakarewa (kaha kutikuti >200 MPa). Kāore e pakaru i raro i te huringa wera, i te pēhanga rānei. Ka whakawhirinaki te paipa kua whakarārangihia ki te mīhini ki te taunga waku – ka taea te miro, te hinga, te wehe rānei ina werahia, ina hurihia rānei. Mō te hinu me te hau nui, te hauwai, te wai hohonu rānei, whiriwhiria tonutia te hononga whakarewa.
P2: Ko tēhea tukanga e homai ana te kaha here teitei rawa?
A: Ko te whakarewatanga pūwero me te whakaputanga wera (kore hononga) ka puta he ≥300 MPa. Ko te herenga hurihuri wera ka puta he 200–260 MPa. He pai ngā mea e rua mō ngā paipa whaimana API 5LD. Ko te whakakikorua pahū ka puta he 200–280 MPa me te atanga ngaru.
Q3: Ka taea e koe te hanga paipa whakakikoruatia ki te paparanga o roto o te titanium, o te zirconium rānei?
Āe, engari ko ēnei te tikanga ka hangaia mā te whakakikorua pahū me te hurihuri pereti. He roa ake te wā arahi. He wheako tō mātou ki ngā paipa whakakikoruatia ki te maitai-tītāniuma mō te whakamatao wai moana me ngā tipu matū.
Q4: Me pēhea te ārai i te waikura o te hononga whakarewa?
A: Kei a mātou te whiringa mō te paninga pata CRA (te whakakikorua i ngā takai) ki te anga o te paipa. Mā tēnei ka tāpirihia he paparanga o te konganuku whakakī koranu (hei tauira, te Koranu 625) ki te mata o te anga, hei ārai i te waimeha o te CRA e te maitai waro i te wā e whakakikoruatia ana. Kātahi ka rite te ātete waikura o te hononga whakakikorua ki te tinana o te paipa.
Q5: He aha ngā tuhinga e whakaratohia ana e koe?
A: Ka whakaratohia e mātou he kōnae kounga katoa e ai ki te whakaahuatanga i te Wāhanga 5.6. Mō ngā ota kua tirohia e te hunga tuatoru, ka tukuna e mātou ngā tiwhikete EN 10204 Momo 3.2 kua hainatia e te whakahaere tirotiro.
Q6: He aha te roanga o te wā arahi?
A: Mō ngā huinga paerewa (hei tauira, X65+316L, herea rōra wera): 8-12 wiki te ota tuatahi, 6-8 wiki ngā ota tuarua. Mō ngā paipa whakakikoruatia kore hononga (pokapū + whakaputanga): 12-16 wiki mō te ota tuatahi. Tāpirihia he 4-6 wiki ki ngā koranu motuhake (titanium, Hastelloy).
Q7: E whakaae ana koe ki ngā ota whakamātautau iti?
Āe. Ka taea e tātou te tīmata me te 20–30 mita mō te whakamātautau tohu, whakamātautau whakangaro rānei. Tērā pea ka roa ake te wā e tatari ana mō te ota whakamātautau nā te whakaritenga.
