Imininingwane Yomkhiqizo

Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

1. Ukubuka Konke Komkhiqizo – Iyini ipayipi le-Bimetal Metallurgical Clad?

Ipayipi elimbozwe ngensimbi ye-bimetal (eyaziwa nangokuthi ipayipi elimbozwe ngensimbi ye-CRA, ipayipi elimbozwe ngensimbi elimelana nokugqwala) liyipayipi elihlanganisiwe elisebenza kahle kakhulu elikhiqizwa yizinqubo zokubopha zensimbi ezithuthukisiwe ezihlanganisa unomphela ungqimba lwangaphakathi lwensimbi emelana nokugqwala (i-CRA) nengqimba yangaphandle yensimbi yekhabhoni enamandla aphezulu noma insimbi ephansi ehlanganisiwe ezingeni le-athomu. Isakhiwo esijwayelekile “i-CRA inner cladding + insimbi eqine kakhulu esekela ngaphandle”.

Lo mklamo "wokumelana nokugqwala kwangaphakathi + amandla angaphandle omshini" uxazulula inselele ebalulekile yobunjiniyela: indlela yokuthutha ngokuthembekile uketshezi olunamandla (i-H₂S ephezulu, i-CO₂ ephezulu, ama-chloride aphezulu) ngaphansi kokucindezeleka okuphezulu kanye nezimo zamanzi ajulile ngaphandle kokusebenzisa amapayipi abizayo e-alloy aqinile.

Ubuchwepheshe basungulwa eShayina ngo-2004 ngokubambisana phakathi kwe-Xinxing Ductile Iron Pipe, i-Panzhihua Steel kanye ne-University of Science and Technology eBeijing, kanye nokuthuthukiswa okulandelayo yi-CNPC BSS, i-Ansteel Group, kanye ne-Baoshi Pipe Industry. Lokhu kuthuthuka kwenze kwaba nokwenzeka ukukhiqizwa kwezinga lezimboni kwamapayipi ambozwe ngensimbi ukuze kube nowoyela negesi emanzini ajulile, amasimu egesi omuncu, ukudluliswa kwe-hydrogen, kanye namaphrojekthi e-CCUS.

I-Womic Steel, eyakhela phezu kwalobu buchwepheshe bepayipi elimboziwe emhlabeni wonke, ihlanganisa i-vacuum hot roll bonding, i-centrifugal casting + i-hot extrusion, kanye namasu okushisela athuthukile aphatha ukuhlanganiswa kwensimbi okuhlukile phakathi kwama-nickel alloys kanye nensimbi yepayipi. Sihlinzeka ngamapayipi amboziwe kusukela ku-60mm kuya ku-1800mm OD anezilungiselelo zobukhulu bodonga eziguquguqukayo, ezihlangabezana ngokuqinile nezindinganiso zomhlaba wonke ezifunwa kakhulu.

4. Inqubo Yokukhiqiza – Ipayipi Lensimbi Eliboshwe Ngensimbi

I-Womic Steel isebenzisa izindlela zokukhiqiza amapayipi agqokelwe ngezinga lomhlaba ukuqinisekisa ukubopha okuqinile kwensimbi kanye nokunemba kobukhulu.

Ukugeleza Kwenqubo (Ukubopha Okushisayo Nokuqedwa Okubandayo):

1. Ukulungiswa kweslabhu ehlanganisiwe– Hlanza futhi uvale ipuleti le-CRA nge-vacuum kanye nepuleti lensimbi elisekelayo ukuze ususe umoya-mpilo; ukugoqa okushisayo ngesilinganiso sokunciphisa okuphezulu kudala ukubopha kwensimbi ngesendlalelo sokusabalalisa.

2. Ukugoqa okushisayo/ukukhipha ipayipi– I-composite slab igoqwa ibe yipuleti bese ikhiwa bese ishintshwa (ipayipi elimbozwe yi-LSAW) noma ikhishwe ibe yipayipi elimbozwe elingenamthungo kusetshenziswa inqubo yokukhipha i-centrifugal + extrusion.

3. Ukudweba okubandayo / ukugoqa okubandayo– Kunciphisa ububanzi nobukhulu bodonga, kuthuthukisa ukuqeda ubuso kanye nokunemba kobukhulu ngenkathi kugcinwa ubuqotho bezibopho.

4. Ukwelashwa ngokushisa– Ukulungisa, ukulungisa + ukulungisa, noma ukucima + ukulungisa (Q&T) ukuze kufezwe izakhiwo ezidingekayo zemishini kanye nokukhululeka ekucindezelekeni.

5. Ukuhlolwa kwe-NDT– Ukuhlolwa kwe-ultrasonic okungu-100% kobuqotho be-bond kanye namaphutha e-laminar; ukuhlolwa kwe-eddy current kanye ne-radiographic njengoba kudingeka.

6. Ukuqeda ukuqeda kanye nokufaka ibhotela le-CRA– Kulungiswa ama-bevel okugcina okushiselwa; kufakwa i-alloy strip cladding ebusweni be-bevel ukuvimbela ukuncibilika kwe-CRA ngesikhathi sokushiselwa kwensimu.

7. Ukuhlolwa kokugcina kanye nemibhalo- Ukuhlolwa okuphelele kobukhulu, ukuhlolwa okubonakalayo, ukulinganiswa kobulukhuni, kanye nokupakishwa ngokwezindinganiso zokuthumela kwamanye amazwe

5. Izinzuzo Eziyinhloko - Ezobuchwepheshe kanye Nezomnotho

●Xazulula inkinga yokugqwala kwepayipi– Kuthuthukisa kakhulu ukuthembeka ezindaweni ze-H₂S, CO₂, Cl⁻, kanye ne-acidic; kuvimbela ukuvuza kokugqwala kanye nokwehluleka kwangaphambi kwesikhathi.

● Izindleko eziphansi zomjikelezo wokuphila– Kufika ku-30-50% ukonga izindleko zezinto uma kuqhathaniswa ne-alloy eqinile ye-nickel noma ipayipi eline-alloy ephezulu.

● Ukuncipha kwe-carbon footprint kanye nokusetshenziswa kwe-alloy– Kuhle kakhulu kumaphrojekthi omnotho we-hydrogen kanye ne-CCS lapho ukusetshenziswa kwezinto eziqhubekayo kubhekwa khona njengenani.

● Ububanzi bosayizi kanye nokuhlinzekwa okuzinzile– OD kusukela ku-60mm kuya ku-1800mm; ubukhulu bodonga nobude kungenziwa ngokwezifiso ukuze kusetshenziswe izintambo ezinde kanye nokufakwa kwe-reel emanzini ajulile.

● Usekelo lwesitifiketi oluqondene nephrojekthi– Nikeza ukuvunyelwa komkhiqizo we-API 5LD, DNV, ABS, amarekhodi okufaneleka kwenqubo yokushisela (WPQR), kanye nezinhlelo zokuhlola ukukhiqiza njengoba kudingeka kumakhasimende.

6. Izicelo Eziyinhloko – Lapho Ipayipi Elimboziwe Liphumelela Kakhulu

●Amapayipi okuthumela uwoyela negesi emanzini ajulile– Imigqa yokugeleza kwamanzi angaphansi kolwandle, ama-riser, kanye nemigqa ye-trunk ephatha uketshezi oluqothulayo nolunomfutho ophezulu.

● Izinhlelo zokuqoqa igesi emuncu ogwini– Amasimu aphezulu e-H₂S/CO₂ (isb., iSichuan basin, Middle East) adinga ukuvikelwa kwe-CRA okuthembekile.

● Ukudluliswa kwe-hydrogen kanye ne-CCUS– Ipayipi elimbozwe nge-bimetal likhethiwe kumapayipi e-hydrogen okuhlola kanye namaphrojekthi e-CO₂-EOR (kufaka phakathi i-CNPC kanye ne-Daqing CCUS) ngenxa yokumelana nokuqhekeka kwe-hydrogen kanye nokusebenza kahle kwezindleko.

● Izitshalo zokuhlanza kanye ne-petrochemical– Amayunithi okubuyisa isibabule esishisa kakhulu, ukwelapha ngamanzi, kanye nemifudlana yenqubo e-chlorine.

● Ukukhiqizwa kukagesi kanye nokumbiwa kwemigodi– Amapayipi odaka lomlotha wamalahle, imigqa yokuhlanza ye-FGD, kanye nokuthuthwa kwemisila enokuguguleka okuphezulu.

9. Imibuzo Evame Ukubuzwa (Imibuzo Evame Ukubuzwa)

Q1: Uyini umehluko obalulekile phakathi kwepayipi elimbozwe ngensimbi kanye nepayipi elimbozwe ngomshini?

A: Ipayipi elifakwe ngomshini lithembele ekungeneleleni kokuphazamiseka ukuze libambe i-liner – ngaphansi kokujikeleza kokushisa kanye nokucindezela, i-liner ingashwabana, iwe noma ihlukane. Ipayipi elifakwe ngomshini elihlanganiswe ngensimbi lakha ungqimba lokusabalalisa phakathi kwe-interface (amandla okugunda >300 MPa). Akukho bungozi bokuhlukaniswa kwe-liner, okwenza kube yinto edingekayo ukuze kusebenze umjikelezo wamanzi ajulile, i-hydrogen kanye nokushisa okuphezulu.

Umbuzo 2: Ingabe i-Womic Steel ingancoma ukumbozwa kwe-CRA okuthile kwensizakalo yami yokugqwala?
A: Yebo. Ithimba lethu lobunjiniyela lihlola ukwakheka koketshezi lwakho (H₂S, CO₂, Cl⁻, pH, ama-organic acid), izinga lokushisa lokusebenza kanye nengcindezi – bese lincoma i-CRA engabizi kakhulu kusukela ku-316L → duplex → nickel alloys. Kumaphrojekthi e-hydrogen sifaka ukuhlolwa okwengeziwe kwe-hydrogen embrittlement.

Q3: Yisiphi isikhathi esijwayelekile sokulethwa kwepayipi elimbozwe nge-API 5LD eliqinisekisiwe?
A: Ukuqinisekiswa kwesihloko sokuqala kanye nokukhiqizwa kwesilingo seqembu cishe izinyanga eziyi-6-8 (kufaka phakathi ukuvunyelwa kohlobo kanye nokuhlolwa kofakazi). Kuma-oda ajwayelekile okuphindaphinda: izinsuku ezingama-60-120 kuye ngokuthi i-OD, izinto ze-CRA kanye nezidingo zokuhlolwa komuntu wesithathu.

UMBUZO 4: I-Womic Steel iqinisekisa kanjani ukumelana nokugqwala kwe-weld ye-girth emajoyintini ensimu?
A: Sifaka i-CRA strip cladding (ibhotela) yasefektri kuzo zombili izimbobo zamapayipi kanye noshintsho olucutshungulwe ngomshini. Lokhu kuvimbela ukuncibilika kwe-CRA ngensimbi esekelayo ngesikhathi sokushisela ensimini. Inqubo yokushisela yamajoyinti e-girth ifaneleka nge-Alloy 625 / 825 filler metal ukuze kugcinwe ukusebenza kokugqwala okulingana nomzimba wepayipi.

UMBUZO 5: Ingakanani imali engayinikezwa yipayipi elimbozwe nge-bimetal uma kuqhathaniswa nepayipi eliqinile le-CRA?
A: Ngokusekelwe ezifundweni zamacala, ipayipi elihlanganiswe kahle ngensimbi ligcina u-30-50% wezindleko zezinto eziphelele uma kuqhathaniswa nepayipi eliqinile le-nickel noma ipayipi eline-alloy ephezulu elinesilinganiso esifanayo sokucindezela. Ukonga kuyanda njengoba ububanzi nobukhulu bodonga bukhuphuka.

Umbuzo 6: Ingabe ipayipi elimboziwe lifanelekile ukuseviswa okumuncu (H₂S) futhi livunyelwe yi-NACE?
A: Yebo. I-CRA cladding (isb. 625, 825, 2205, 316L) ehlanganiswe nensimbi esekelayo efanele (isb. X65MS, X52NS) inganikezwa ngokuhambisana ngokugcwele ne-NACE MR0175 / ISO 15156 kanye ne-API 5L Annex H. Ukuqina, i-SSC kanye nokuhlolwa kwe-HIC kungenziwa futhi kubhalwe phansi.

10. Cela Isilinganiso

I-Womic Steel inikeza izixazululo zamapayipi enziwe ngensimbi ye-bimetal ezenziwe ngokwezifiso - sisebenzisa amandla ensimbi yekhabhoni kanye nokumelana nokugqwala kwe-CRA. Sisebenzela uwoyela negesi emanzini ajulile, amasimu omuncu asogwini, amapayipi e-hydrogen kanye nezinhlelo zokusebenza ze-CCUS EOR emhlabeni jikelele.
