Intshayelelo
Xa sijonga ihlabathi lanamhlanje—ukusuka kwimida yezixeko zethu ezinkulu ukuya kwiinethiwekhi zamandla ezingabonakaliyo ezinika amandla amakhaya ethu—kukho iqhawe elithuleyo eliphethe ubunzima benkqubela phambili: umbhobho wentsimbi omkhulu.
Nangona kunjalo, kwihlabathi lobunjineli obunzima, ayizizo zonke iipayipi ezidalwe ngokulinganayo. Xa iprojekthi isuka "kwimigangatho" iye "kwimigangatho ephezulu" - equka uxinzelelo olukhulu, iindawo ezinobungozi ezinzulu zolwandle, okanye imithwalo ebalulekileyo yesakhiwo - ishishini liyayeka ukukhetha izinto eziqhelekileyo. Endaweni yoko, umgangatho wegolide ubaI-LSAW(I-Longitudinal Submerged Arc Welded)iipayipi, ingakumbi ezo zenziwe ngezixhobo ezintsonkothileyoI-JCOEinkqubo.
Kodwa yintoni ngokwenene eyahlula umbhobho we-JCOE kwityhubhu eqhelekileyo ejikelezayo? Kwaye ipleyiti yesinyithi esithe tyaba iguquka njani ibe yinqanawa enoxinzelelo oluphezulu ekwaziyo ukuhlala phantsi kolwandle iminyaka engamashumi amahlanu? Esi sikhokelo sihlola ingqiqo yobunjineli, ubunzima bokuvelisa, kunye nemigangatho yemarike echaza obu buchwepheshe bentsimbi bubalulekileyo.
Ukucacisa isigama soShishino
Ukuze siqonde ukuba kutheni le mibhobho ibiza ixabiso eliphezulu, kufuneka siqale sicacise ulwimi olusetyenziswa kwiinkcukacha zobugcisa.
Ukuqonda i-LSAW Umbhobho we-LSAWibhekisa kwindlela yokuwelda. Ngokungafaniyo nemibhobho edibeneyo ejikelezayo (I-SSAW), ezenziwe njengeroli yetawuli yephepha lekhadibhodi enomthungo ojikelezayo, iipayipi ze-LSAW zine-weld enye, ethe tye ehamba ubude bonke.
Umda woBunjineli:Umthungo othe tye mfutshane kakhulu kunowokujikeleza. Kwihlabathi lolawulo lomgangatho, umthungo omfutshane uthetha "uphawu lwezibalo" oluncinci kwiziphene ezinokubakho. Yingakho i-LSAW ilukhetho olungenakuthethwa ngalo lokuhambisa igesi yendalo enobungozi obukhulu.
Ukuchaza i-JCOEYimpazamo eqhelekileyo ukucinga ukuba i-JCOE yimveliso; eneneni yimvelisoumdaniso woomatshiniIsifinyezo simele utshintsho olubonakalayo oludlulayo kwintsimbi:
J:Ukuqhekeka kokuqala kwemiphetho yepleyiti.
C:Ukugoba isiqingatha sokuqala sepleyiti.
O:Ukuvala isangqa.
E:Isigaba esibalulekileyo "soKwanda" esigqibezela ukuthembeka kombhobho.
Uhambo Lokuvelisa: Ukusuka Kwipleyiti Ukuya Kwichanekile
Ukuveliswa kombhobho we-LSAW ludidi oluphezulu ekusebenzeni ngesinyithi esinzima. Yinkqubo enobudlova kodwa echanekileyo eguqula ipleyiti eluhlaza ibe sisixhobo esisebenza kakuhle.
1. Ukulungiswa komphetho
Yonke into iqala ngepleyiti yentsimbi enzima. Ngaphambi kokuba kwenzeke nakuphi na ukugoba, imiphetho iyasilwa ibe zii-engile ezichanekileyo. Oku kuqinisekisa ukuba xa amacala omabini ekugqibeleni edibana, i-"V-groove" ifanelekile kwi-deep-penetration welding.
2. Ulandelelwano Lokwenza iJCO
Kulapho ke ii-hydraulic ezinzima zingena khona. Uxinzelelo olukhulu lusebenzisa amawaka eetoni zoxinzelelo ngamanqanaba:
Ukwenziwa kwe-J:I-press ijika icala elinye lepleyiti, idale iprofayili ethi “J”.
Ukwenziwa kwe-C:Ipleyiti iyajikwa okanye itshintshelwe kwenye indawo, kwaye elinye icala liyagoba ukuze lifane nelokuqala, nto leyo ephumela ku-“C” ovulekileyo.
Ukwakheka kwe-O:Isikhungo sicinezelwe phantsi, sidibanisa imiphetho emibini ukuze senze u-“O” ovaliweyo.
3. Ukuwelda kwe-Arc engaphantsi kwamanzi (i-SAW)
Xa umthungo uvaliwe, umbhobho ungena kwisitishi sokuwelda. Inxalenye yegama elithi “Ifakwe ngaphantsi” ibhekisa kumaleko we-granular flux egquma i-arc. Oku akupheleli nje ekukhuselekeni; kuyayihlukanisa isinyithi esinyibilikisiweyo kwi-oxygen yomoya-mpilo, nto leyo ethintela ukuwelda okubuthathaka. Uninzi lweepayipi ezikumgangatho ophezulu ziwelda kabini—kanye ngaphakathi nangaphandle—ukuqinisekisa ukuba kukho i-bond eyi-100%.
4. "E" – Ukwandiswa koomatshini (Umtshintshi womdlalo)
Eli lelona nyathelo lingaqondakaliyo. Emva kokuwelda, umbhobho awujikelezi kakuhle, kwaye uzele "luxinzelelo" lwangaphakathi ngenxa yokugoba. Isandisi-mbane esinomatshini sifakwa kumbhobho size sityhalelwe ngaphandle. Okuiyanda ngokubandayointsimbi nge-1%, nto leyo eyinyanzela ukuba ibe yisangqa esigqibeleleyo, kwaye, okubaluleke kakhulu, ikhulula uxinzelelo lwangaphakathi. Yingakho iipayipi ze-JCOE zinomlinganiselo ongcono kakhulu wokunyamezelana kunezo zikhuphisana nazo.
Iinkcukacha zoBugcisa kunye neMigangatho yokuThenga
Kwiinjineli kunye namagosa okuthenga, "iphepha elithile" yiBhayibhile. Itekhnoloji ye-JCOE yenzelwe "izinto ezinkulu," kwaye amanani abonisa loo nto.
| Uphawu | Ubuchule obuqhelekileyo |
| Ububanzi obungaphandle | 16″ (406mm) ukuya kuma-56″ (1422mm) |
| Ubukhulu bodonga | 6mm ukuya kuthi ga kwi-40mm+ (Ingenziwa ngokwezifiso xa kupakishwa izinto ezinzima) |
| Amabanga aqhelekileyo | I-API 5L (X42 ukuya ku-X80), ASTM A252, EN 10219 |
Iingubo Zokusinda: “Ulusu” Lombhobho
Ekubeni ezi zinto zihlala zingcwatywa okanye zifakwe emanzini amashumi eminyaka, ulusu lubaluleke njengentsimbi.
3PE/3PP:Umgangatho weshishini wokumelana nokugqwala. I-3PP (iPolypropylene) ikhethwa kakhulu kwizinto ezikwiqondo lobushushu eliphezulu.
I-CWC (Ukwaleka kobunzima bekhonkrithi):Ngokukodwa kwiintambo zamanzi angaphantsi kolwandle. Ikhonkrithi ayikhuseli nje kuphela, yongeza ubunzima obufunekayo ukuze umbhobho ungahambi emanzini.
Ukwambathisa Ukuhamba Kwangaphakathi:Umaleko we-epoxy othambileyo onciphisa ukungqubana, nto leyo eyenza umbhobho "ukhawuleze" ukuhamba kweoyile negesi.
Izicelo Ezineengxaki Eziphezulu
Uyifumana phi i-LSAW? Ngokwesiqhelo, kwiindawo apho ukuvuza okanye ukudilika kungaba yintlekele.
1.Imithambo Yamandla Exinezelekileyo:Xa kushukunyiswa igesi eguquguqukayo kwiingcinezelo ezingaphezulu kwe-10 MPa, ukuthembeka komthungo omnye we-longitudinal kuyimfuneko.
2.Iziseko zeZakhiwo:Ngenxa yodonga lwazo oluqinileyo, iipayipi zeJCOE zezona zikhethwayo zokuqala kwiiplanga zeebhulorho kunyeIiMonopiles zomoya zasolwandle, apho kufuneka bamelane nokubetheka okungapheliyo kwamaza olwandle.
3.Iinkonzo zamanzi ezibalulekileyo:Izixeko ezinkulu zisebenzisa i-LSAW njengeendlela zazo eziphambili zamanzi ukuqinisekisa ukuba umngcipheko wokukhukuliswa kwamanzi ezidolophini ngenxa yombhobho oqhumayo ugcinwa usezantsi kakhulu.
Ukujonga Phambili: Ummandla weHydrogen
Eli shishini okwangoku lijikeleza ukuyaIlungele i-hydrogenimibhobho. Iimolekyuli zehydrogen zincinci kwaye zinokubangela "ukubhitya" kwintsimbi eqhelekileyo. Iifektri zanamhlanje ze-LSAW sele zizama isinyithi esitsha kunye neengubo zangaphakathi ezikhethekileyo ukulungiselela utshintsho lwamandla aluhlaza. Ngaphezu koko, ukungeniswa kwe-AI eqhutywa yi-AIUvavanyo lwe-Ultrasonic oluzenzekelayo (AUT)yenza impazamo yomntu ekuhlolweni kwe-weld ibe yinto yexesha elidlulileyo.
Iingcinga Zokugqibela
Umbhobho we-LSAW owenziwe yi-JCOE "ngumatshini wezixhobo ezinzima" kwihlabathi leziseko zophuhliso. Udibanisa amandla angabonakaliyo omzimba kunye nokuchaneka kwejometri. Nangona utyalo-mali lokuqala luphezulu kunelo lombhobho ojikelezayo, i-ROI yexesha elide ifumaneka ekuthembekeni kwayo. Kwixesha apho sifuna iziseko zophuhliso zihlale iminyaka engaphezu kwama-50 phantsi kweemeko zokusingqongileyo ezinzima ngakumbi, i-JCOE iseyeyona khetho ithembekileyo yenjineli.
