    Amathegi Omkhiqizo

    Ngenisa

    Ubuciko bokuthiukushisela ipayipi lensimbikudinga inhlanganisela evumelanayo yamakhono, ukunemba kanye nezinto zekhwalithi ukuqinisekisa ubuqotho besakhiwo sezinhlelo zokusebenza ezahlukahlukene. Phakathi kwezinhlobo eziningi zamapayipi, ipayipi lensimbi yekhabhoni elihlanganisiwe elihlanganisiwe, njengepayipi le-X42 SSAW, lidumile ngamandla alo aphezulu, ukuqina kanye nokusebenza kahle kwezindleko. Kule bhulogi, sizohlola ukubaluleka kwamapayipi ensimbi yekhabhoni ahlanganisiwe ahlanganisiwe enkambisweni yokushisela amapayipi ensimbi, sihlolisise inqubo yayo yokukhiqiza, izinzuzo kanye nezindawo zokusetshenziswa.

    a. Indlela yokususa i-oxidation ichazwa kanje:
    FF: Insimbi ebulewe ngokuphelele equkethe izinto zokubopha i-nitrogen ngamanani anele ukubopha i-nitrogen etholakalayo (isb. ubuncane be-0,020% iyonke i-Al noma i-0,015% i-Al encibilikayo).
    b. Inani eliphezulu le-nitrogen alisebenzi uma ukwakheka kwamakhemikhali kubonisa okuqukethwe okungenani kwe-Al okungu-0,020% kanye nesilinganiso esincane se-Al/N esingu-2:1, noma uma kukhona ezinye izinto ezibophayo ze-N ezanele. Izinto ezibophayo ze-N kufanele ziqoshwe kuDokhumenti Yokuhlola.

    Inqubo yokukhiqiza

    Ipayipi elihlanganisiwe elijikelezayo, elaziwa nangokuthi ipayipi le-SSAW (ipayipi elihlanganisiwe elijikelezayo elihlanganisiwe), lenziwa kusetshenziswa amasu okushisela i-spiral forming kanye ne-submarine arc. Inqubo iqala ngokwelashwa komphetho we-coiled steel strip bese igoba i-strip ibe yi-spiral shape. I-arc welding ezenzakalelayo engaphansi komhlaba isetshenziswa ukuhlanganisa imiphetho ye-strip ndawonye, ​​​​idale i-weld eqhubekayo ngobude bepayipi. Le ndlela iqinisekisa ukuthi i-joint iqinile futhi ihlala isikhathi eside ngenkathi inciphisa amaphutha futhi igcina ubuqotho besakhiwo.

    Izinzuzo zepayipi lensimbi yekhabhoni elihlanganisiwe eliyindilinga

    1. Amandla nokuqina:Ipayipi lensimbi yekhabhoni elihlanganisiwe elihlanganisiweyaziwa ngamandla ayo aphezulu kanye nokuqina kwayo, okwenza ifaneleke ezinhlelweni zokusebenza ezidinga ukumelana nokucindezela okuphezulu kanye nokusebenza kwesikhathi eside.

    2. Ukuphumelela Ngezindleko: Lawa mapayipi anikeza ikhambi eliphumelelayo ngenxa yenqubo yawo yokukhiqiza ephumelelayo, izindleko zezinto zokusetshenziswa eziphansi, kanye nezidingo zabasebenzi ezincishisiwe uma kuqhathaniswa nezinye izinhlobo zamapayipi.

    3. Ukuguquguquka: Ukuguquguquka kwepayipi lensimbi yekhabhoni elihlanganisiwe eliyindilinga kuvumela ukuthi lisetshenziswe ezinhlobonhlobo zezicelo, okuhlanganisa ukuthuthwa kwamanzi, ukuthuthwa kukawoyela negesi, izakhiwo zokufaka inqwaba, izinhlelo zokuthutha indle, kanye nezinqubo ezahlukahlukene zezimboni.

    4. Ukunemba kobukhulu: Inqubo yokwakha i-spiral ingalawula ngokunembile usayizi kanye nobukhulu bodonga lwepayipi, iqinisekise ukunemba kanye nokufana kokukhiqiza.

    Izindawo zokufaka isicelo

    1. Imboni kawoyela negesi yemvelo: Amapayipi ensimbi yekhabhoni ahlanganisiwe asetshenziswa kabanzi embonini kawoyela negesi yemvelo, ikakhulukazi ekuthuthweni kukawoyela ongahluziwe, igesi yemvelo kanye nemikhiqizo kaphethiloli. Amandla awo kanye nekhono lokubekezelela izindawo ezinomfutho ophezulu kuwenza afaneleke kakhulu kumapayipi aqhelelene.

    2. Ukudluliselwa Kwamanzi: Kungakhathaliseki ukuthi kuhlinzekwa ngamanzi kamasipala noma ngezinjongo zokunisela, amapayipi ensimbi yekhabhoni ahlanganisiwe nge-spiral ahlinzeka ngesisombululo esihle kakhulu ngenxa yokumelana kwawo nokugqwala, amandla kanye nokulula kokufakwa kwawo.

    3. Ukusekelwa kwesakhiwo: Lolu hlobo lwepayipi lusetshenziswa kabanzi embonini yokwakha ukuhlinzeka ngokusekelwa kwesakhiwo sezakhiwo, amabhuloho, amachweba kanye neminye imisebenzi yengqalasizinda. Ukuqina kwawo kanye nokumelana nezinto zangaphandle kuwenza athembeke kulezo zicelo.

    4. Izicelo Zezimboni: Amapayipi ensimbi yekhabhoni ahlanganisiwe asetshenziswa emikhakheni eyahlukene yezimboni njengokucubungula amakhemikhali, izitshalo zikagesi kanye nemisebenzi yezimayini ngenxa yekhono lawo lokusingatha amazinga okushisa aphezulu, ukucindezela kanye nezindawo ezigqwalisayo.

    Ekuphetheni

    Ipayipi lensimbi yekhabhoni elihlanganisiwe elihlanganisiwe, njengeIpayipi le-X42 SSAW, iguqule inqubo yokushisela amapayipi ensimbi, iletha izinzuzo eziningi ezimbonini ezahlukene. Amandla azo, ukuqina, ukusebenza kahle kwezindleko kanye nokunemba kobukhulu kuqinisekisa ubuqotho besakhiwo ezinhlotsheni ezahlukene zezicelo. Amandla okubekezelela ukucindezeleka okukhulu, amazinga okushisa kanye nezindawo ezigqwalisayo kwenza kube kuhle kakhulu ekudlulisweni kukawoyela negesi, ukuhlinzekwa kwamanzi kanye neminye imikhakha yezimboni. Ngakho-ke, uma kukhulunywa ngokushisela amapayipi ensimbi, ukusetshenziswa kwamapayipi ensimbi ekhabhoni ashiselwe nge-spiral kuhlala kuyisisombululo esithembekile nesisebenzayo sokuqinisekisa ingqalasizinda ehlala isikhathi eside futhi eqinile.

    Ukuhlolwa Kwamanzi

    Ubude bepayipi ngalinye kufanele buhlolwe ngumenzi ngengcindezi ye-hydrostatic ezokhiqiza odongeni lwepayipi ukucindezeleka okungaphansi kuka-60% wamandla amancane okukhiqiza ashiwo ekushiseni kwegumbi. Ukucindezela kuzonqunywa yi-equation elandelayo:
    P=2St/D

    Izinguquko Ezivumelekile Ezisindweni Nasezilinganisweni

    Ubude bepayipi ngalinye kufanele bulinganiswe ngokwehlukana futhi isisindo salo akumele sihluke ngaphezu kuka-10% noma u-5.5% ngaphansi kwesisindo salo esicatshangelwayo, kubalwe kusetshenziswa ubude balo kanye nesisindo salo ngobude beyunithi ngayinye.
    Ububanzi bangaphandle akufanele buhluke ngaphezu kuka-±1% kusuka kububanzi obujwayelekile bangaphandle obubekiwe
    Ubukhulu bodonga nganoma yisiphi isikhathi akufanele bube ngaphezu kuka-12.5% ​​ngaphansi kobukhulu bodonga obubekiwe
