1. Kuki wahitamo umuyoboro upfutse - kandi kuki wakora Womic Steel?
Umuyoboro upfutse uhuzaicyuma cyo hanze gifite imbaraga nyinshi za karuboni cyangwa aloyi nkeya(ihangana n'umuvuduko, umutwaro w'imashini, n'ikiguzi) ikoreshejeurwego rw'imbere rw'icyuma kirwanya ingese(ikora ku buryo butaziguye ku mazi ashyushye). Iyi nyubako ifite ibyiciro bibiri igabanya ikiguzi cy'ibikoresho ho 30–60% ugereranije n'umuyoboro ukomeye wa CRA, mu gihe itanga uburinzi bungana n'ubwangizi n'ubuzima bwa serivisi.
Nk'umuntuuruganda rukora imiyoboro ipfutse, Womic Steel ntabwo itanga gusa urutonde rw'ibikoresho. Dutangirana n'imiterere y'imikorere yawe: H₂S, CO₂, Cl⁻, pH, ubushyuhe, igitutu, igitutu cya hydrogen, n'ibisabwa na mekanike. Hanyuma turagusaba guhuza icyuma gifata inyuma, CRA cladding, n'uburyo bwo gufatanya.
Ubunararibonye bwacu buturuka ku mishinga nyayo - ahantu hashyushye ho mu mazi, aho amazi yo munsi y'inyanja yinjirira, amamashini ashyushya cyane, imiyoboro ya hydrogen pilot, na sisitemu zo guteramo CCUS-EOR. Turasobanukiwe ko umuyoboro upfutse atari ikintu gicuruzwa; ni ikintu cyakozwe mu buryo bwa tekiniki.
2. Uburyo bwo gupfuka – Uburyo duhuza ibyuma bibiri
Urufunguzo rw'umuyoboro wizewe upfutse niuburyo bwo guhuzahagati y'icyuma gishyigikira icyuma n'urwego rwa CRA. Hasi hari inzira enye z'ingenzi dukoresha, zitondekwa hakurikijwe imbaraga z'imigozi n'uburyo ikoreshwa rikwiriye.
2.1 Gucana hagati y'amazi + Gusohora ibintu bishyushye (Umugozi w'icyuma udafite umugozi)
Uko bikora:
Urukuta rwa CRA rubanza gushyirwa mu muyoboro w’ubusa udafite ikintu. Hanyuma uyu muyoboro ushyirwa mu cyuma cya karuboni, ugashyuha, hanyuma ugasohokana binyuze mu gikoresho kinini cyo gusohora. Iyo ubushyuhe n’umuvuduko biri hejuru, ibyuma byombi birakwirakwira, bigakora isano nyayo y’icyuma.
Ibiranga umugozi:
● Ingufu zo gukata umurongo ≥300 MPa (ni zo hejuru mu nzira zose)
● Nta mugozi uhambiriyeho ubudodo burambuye - nta mugozi uhambiriyeho
● Ubunini bw'igipfundikizo bungana, ingano nyazo
Ikwiriye cyane kuri:
Uduce duto kugeza kuri duto (≤400mm – ~16″), umuvuduko mwinshi, ubwihindurize bukabije bw'ubushyuhe, serivisi ya hydrogen, imiyoboro ya boiler, imiyoboro yo hasi, icyuma gihindura ubushyuhe U-bends.
2.2 Guhuza uruziga rushyushye + JCOE / UOE Forming
Uko bikora:
Isahani ya CRA n'isahani y'icyuma cya karuboni birasukurwa, bigashyirwa mu cyuma gifunze, bigafungwa, bigashyuha, hanyuma biganyuzwa mu cyuma gisya. Inzira nyinshi zo gusimbuka zikora umugozi w'icyuma. Isahani ipfundikiye ikorwamo umuyoboro hakoreshejwe JCOE (JCO-Edge) cyangwa UOE press forming, hanyuma bigakurikirwa no gusudira umugozi mu buryo bwa longitudinal.
Ibiranga umugozi:
● Ingufu zo gukata umurongo hagati ya 200–260 MPa
● Ubwinshi bushoboka cyane (kugeza kuri 1,800mm / 72″)
● Uburebure burebure (kugeza kuri metero 24 cyangwa zirenga)
● Irimo umugozi umwe wo gusudira mu gihe kirekire (igomba kuba yujuje ibisabwa kandi igenzurwa na NDT)
Ikwiriye cyane kuri:
Imiyoboro minini y'uburebure burebure, inzira z'amazi yo munsi y'inyanja, inzira z'imirongo, n'izamuka ry'amazi. Iyi ni yo nzira ikoreshwa cyane ku muyoboro wemewe wa API 5LD.
2.3 Gupfuka ibisasu + Gutembera kw'isahani
Uko bikora:
Isahani ya CRA ishyirwa hejuru y'isahani y'icyuma cya karuboni ifite icyuho cyabazwe, hanyuma igatwikirwa n'ibisasu. Igisasu gitera isahani ya CRA kwinjira mu isahani y'inyuma ku muvuduko mwinshi, bigatuma habaho isano igonganye kandi ikora nk'icyuma. Isahani ipfutse irazingirwa hanyuma igashyirwa mu muyoboro.
Ibiranga umugozi:
● Interineti igororotse ifite imbaraga nziza zo gufatanya (200–280 MPa)
● Ishobora guhuza ibyuma bitandukanye bigoye kubihuza (urugero: titaniyumu n'icyuma, zirconium n'icyuma)
● Ingano y'ikibaho igengwa n'ibikoresho biturika; gusudira nyuma birakenewe
Ikwiriye cyane kuri:
Uruvange rw'ibintu bidasanzwe: titaniyumu/icyuma, zirconium/icyuma, tantalum/icyuma cyo gukoresha imiyoboro y'ibinyabutabire ikoreshwa cyane mu bimera ndetse n'ibikoresho bihindura ubushyuhe.
2.4 Imitako y'imashini (Ntibisabwa gukoreshwa mu mirimo y'ingenzi)
Uko bikora:
Umuyoboro wa CRA ugenda wongerwamo ubukonje cyangwa waguwe hifashishijwe hydraulic mu muyoboro w'icyuma cya karuboni. Ibice byombi biguma hamwe bitewe n'uko bihura n'ikibazo (hoop stress).
Ibiranga umugozi:
●Nta bufatanye bw'ibyuma– gukoraho gusa umubiri
● Ingufu z'umugozi <10 MPa
● Ingufu zishobora gucika intege, gusenyuka, cyangwa gucika bitewe n'ubushyuhe cyangwa umuvuduko ukabije
Iyo tuyikoresheje:
Gusa ku bushyuhe buke, umuvuduko muke, serivisi idahindagurika, idahindagurika, kandi gusa iyo umukiriya yemeye neza ko nta mbogamizi afite. Buri gihe dusobanura ingaruka ugereranyije n'imiyoboro ipfundikiye ikoresheje ibyuma.
Inama yacu:Ku birebana na peteroli na gaze, hydrogen, cyangwa amazi y'ubujyakuzimu, hitamo umuyoboro ufatanye n'icyuma – ntabwo ari umuyoboro ufatanye n'icyuma.
3. Ubuyobozi bwo Guhitamo Inzira - Incamake y'Icyo Ukora

8. Ibibazo Bikunze Kubazwa (Ibibazo Bikunze Kubazwa)
Q1: Ni irihe tandukaniro nyaryo riri hagati y'imiyoboro ifatanye mu byuma n'imiyoboro ifatanye mu byuma?
A: Umuyoboro ufatanye n'icyuma ufite urwego rwo gukwirakwiza mu rwego rwa atome (imbaraga zo gukata >200 MPa). Ntabwo uzacika bitewe n'ubushyuhe cyangwa umuvuduko w'umuvuduko. Umuyoboro ufatanye n'icyuma ushingira ku buryo bwo gukururana - ushobora gushwanyagurika, gusenyuka cyangwa gutandukana iyo ushyushye cyangwa ukoresheje amagare. Ku bijyanye na peteroli na gaze, hidrojeni, cyangwa amazi yo mu burebure, hitamo buri gihe umuringa ufatanye n'icyuma.
Q2: Ni iyihe nzira itanga imbaraga nyinshi zo guhuza?
A: Gucana centrifugal + gusohora umuriro ushyushye (bidakora neza) bikunze gutanga ≥300 MPa. Guhuza umugozi ushyushye bitanga 200–260 MPa. Byombi bikwiranye n'umuyoboro wemewe na API 5LD. Gupfuka ibisasu bitanga 200–280 MPa hamwe n'aho bihurira.
Q3: Ese ushobora gukora umuyoboro upfutse ukoresheje titanium cyangwa zirconium imbere?
A: Yego, ariko ibi bikunze gukorwa no gupfuka ibisasu bitwikiriye + gupfuka plate. Igihe cyo gupfuka ni kirekire. Dufite ubunararibonye mu miyoboro ipfukanywe na titaniyumu mu gukonjesha amazi yo mu nyanja no mu nganda zikora imiti.
Q4: Ni gute wakwirinda ingese yo kwangirika kw'imigozi ku gice cy'umugozi?
A: Dutanga uburyo bwo gukoresha CRA buttering (strip cladding welding) ku mugozi w'umuyoboro. Ibi byongeraho urwego rw'icyuma cyuzuza alloy (urugero, Alloy 625) ku ruhande rw'umugozi, bikarinda ko CRA igabanuka bitewe n'icyuma cya karuboni mu gihe cyo gusudira mu murima. Hanyuma umugozi wo gusudira ufite ubudahangarwa bungana n'ubw'umugozi.
Q5: Ni izihe nyandiko utanga?
A: Dutanga dosiye yuzuye y’ubuziranenge nk’uko bivugwa mu Gika cya 5.6. Ku mabwiriza yagenzuwe n’abandi bantu, dutanga ibyemezo bya EN 10204 Type 3.2 byashyizweho umukono n’urwego rushinzwe kugenzura.
Q6: Igihe gisanzwe cyo gutanga umusanzu ni ikihe?
A: Ku bivange bisanzwe (urugero, X65+316L, hot roll bonded): commande ya mbere ibyumweru 8-12, subiramo commande ibyumweru 6-8. Ku muyoboro udafite umugozi (centrifugal + extrusion): ibyumweru 12 kugeza 16 ku commande ya mbere. Alloys zidasanzwe (titanium, Hastelloy) zongerwaho ibyumweru 4-6.
Q7: Ese wemera amabwiriza mato yo kugerageza?
A: Yego. Dushobora gutangirana na metero 20–30 kugira ngo tubone ibizamini byo gupima cyangwa byangiza. Igihe cyo gutangira igerageza gishobora kuba kirekire gato bitewe n'uko byashyizweho.
9. Gupakira no Kohereza
●Uburinzi bw'ubuso:Amavuta arwanya ingese ku gice cyo hanze cy'icyuma gifashe inyuma; ubuso bw'imbere bwa CRA buguma bwumye cyangwa bufunze azote.
●Ingofero z'inyuma:Imipfundikizo minini ya pulasitiki ihambiriweho imigozi y'icyuma.
● Guhuza:Ku mpande nto (kugeza kuri santimetero 8), uduce duto tw’ibiti dufite utubari duto. Ku mpande nini, uduce dushyigikira uduce duto.
● Gupakira amakontena:Ibikoresho bifite metero 20 cyangwa 40 bifite imifuka y'udupfunyika n'imishumi y'icyuma.
● Akabati ko gupfunyikamo ibintu byinshi / gafite aho guhagarara:Ku muyoboro munini w'umurambararo (≥24″) cyangwa umuyoboro munini wo ku rukuta.
● Ikimenyetso:Ikaseti kuri buri API 5LD / ibisabwa n'umukiriya. Umubare w'ubushyuhe ushobora gukurikiranwa kuri buri metero.
