    Zazise

    Ubugcisa beI-pie yentsimbi yentsimbiIfuna indibaniselwano yesakhono ehambelana nobuchule, iccional kunye nezinto eziphathekayo ukuqinisekisa ukuthembeka ngokwasekwakhiweni kwezicelo ezahlukeneyo. Phakathi kweendidi ezininzi zombhobho, umbhobho we-Welbon we-Spilbon ye-carbon, onjengombhobho we-X42 SSAW, uyathandwa ngamandla ayo aphezulu, ukuqina kunye nokusebenza ngempumelelo. Kwezi bhlog, siya kuphonononga ukubaluleka kwemibhobho ye-Welbon ye-widbon ye-widbon kwinkqubo ye-wellung yentsimbi, iphosela kwinkqubo yayo yokwenyama, isebenza kwinkqubo yayo yokwenziwa, iingenelo kunye neendawo ezinokwenza izicelo.

    a. Indlela ye-Deaxotion ichongwe ngolu hlobo lulandelayo:
    I-FF: Intsimbi egcinwe ngokupheleleyo i-nitrogen ebophelelayo kwizixa ezaneleyo zokubopha initrogen (umz. I-0,020% ye-al).
    b. Elona xabiso liphezulu le-nitrogen alisebenzi ukuba ukubekwa kwekhemikhali kubonisa i-0,020% ye-al / n i-2: 1, okanye ukuba izinto ezaneleyo ze-N-Bing zikhona. Izinto ezibophelelayo ziya kurekhodwa kuxwebhu lovavanyo.

    Inkqubo yokwenziwa kwemveliso

    I-Spiral Deped Ped, ekwabizwa ngokuba yi-SSAW (i-SPIRAL ye-ARC ye-PARCED) yenziwayo, isebenzisa ukusebenzisa ubuchwephesha be-spiral kunye ne-Arc enamanzi amaninzi. Inkqubo iqala ngonyango lomphetho wensimbi yentsimbi kwaye emva koko igobe umtya ube yindawo ye-spiral. I-Arc ye-Arc esenzekelayo ye-ARC ye-ARC isetyenziselwa ukujoyina imiphetho yemitya, eyenza i-sld eqhubekayo ngobude bombhobho. Le ndlela iqinisekisa ukuba i-dibanise inamandla kwaye iqinile ngelixa incipha ingozi kunye nokugcina ingqibelelo.

    Izinto eziluncedo kumphunga we-spilbon yentsimbi

    1. Amandla kunye nokuqina:I-Spil Welbon ye-SPOND PAEL PAELYaziwa ngamandla ayo aphezulu, ukuqina, iyenza ilungele izicelo ezifuna ukumelana noxinzelelo kunye nokusebenza kwexesha elide.

    2. Ukusebenza kweendleko: Le mibhobho ibonelela ngesisombululo esisebenzayo ngenxa yenkqubo yabo efanelekileyo yokwenza imveliso, indleko eziphantsi zexabiso, kunye nokuncitshiswa kwemisebenzi yokusebenza xa kuthelekiswa nezinye iintlobo zemibhobho.

    I-3. Ukungaguquguquki

    4. Ukuchaneka kwendlela: Inkqubo yokuqulunqwa kweSpiral inokulawula ngokuchanekileyo ubungakanani kunye nobubanzi bodonga, ukuqinisekisa ukuchaneka kunye nokufaniswa kwemveliso.

    Ukutyibilika kwe-pec

    Iindawo zesicelo

    I-1. Ishishi yegesi kunye nendalo yendalo: Imibhobho yentsimbi ye-SPOLD isetyenziswe ngokubanzi kwi-oyile kunye ne-oyile yegesi yendalo, ngakumbi kwi-oyile ye-oyile ecekeceke, igesi yemvelo kunye ne-petroleum yemvelo. Amandla abo kunye nokukwazi kwabo ukumelana neemeko zoxinzelelo oluphezulu zibenza balungele imibhobho emide.

    2. Ukuhanjiswa kwamanzi: Nokuba ngaba ubonelelo lwamanzi kamasipala okanye ukunkcenkceshela, imibhobho ye-Welbon ye-SPOND ibonelela ngesisombululo esihle ngenxa yokungaxhathisi babo, amandla kunye nokukhululeka kunye nokufakelwa kokufakwa kwabo.

    3. Inkxaso yolwakhiwo: Olu hlobo lombhobho lusetyenziswa ngokubanzi kwishishini lokwakha ukubonelela ngenkxaso yezakhiwo kwizakhiwo, iibhulorho, iibhlorho kunye nezinye iiprojekthi zeziseko zophuhliso. Ukuqina kwabo kwaye ukumelana nezinto zangaphandle kubenza bathembeke kwizicelo ezinjalo.

    I-4. Izicelo zemveliso: Imibhobho ye-Welbon ye-Carbon ye-Carbon isetyenziswa kumacandelo ahlukeneyo emizi-mveliso, izityalo zamandla kunye nokusebenza kwemigodi ngenxa yokukwazi ukujongana nobushushu obuphakathi, iingcinezelo kunye neendawo ezinomngcipheko.

    Ukuququmbela

    I-Spiral Welbon Stebon yentsimbi, enjeI-X42 SSAW PIP, ihambise inkqubo ye-wellding yentsimbi, ngokuzisa izibonelelo ezininzi kumashishini ahlukeneyo. Amandla abo, ukuqina, ukusebenza ngempumelelo kunye nokuchaneka kwexabiso kunye nokuchaneka komgangatho okuqinisekisa ingqibelelo kwizicelo ezahlukeneyo. Amandla okumelana neengcinezelo ezigqithileyo, amaqondo obushushu kunye neemeko zoncedo zenza ukuba ilungele ukuhanjiswa kweoyile kunye negesi, ukubonelela ngamanzi kunye namanye amacandelo avela kwimizi-mveliso. Ke ngoko, xa kufikwa kwi-welding yentsimbi yentsimbi, ukusetyenziswa kwe-spild ye-spilbon yemibhobho ye-spilbon kuhlala isisisombululo esinokuthenjwa kwaye sisebenza ngokufanelekileyo ukuqinisekisa izakhiwo ezihlala ixesha elide kunye nezilulo.

    Uvavanyo lwe-hydrostatic

    Ubude bombhobho buya kuvavanywa ngumenzi kwingcinezelo ye-hydrostatic eya kuthi ivelise udonga lombhobho woxinzelelo olungaphantsi kwe-60% yamandla egumbi elichaziweyo kubushushu begumbi. Ingcinezelo iya kugqitywa ngale quation ilandelayo:
    P = 2st / d

    Umahluko ovumelekileyo kwimilinganiselo kunye nobungakanani

    Ubude bombhobho buya kuba bunzima ngokwahlukeneyo kwaye ubunzima bayo bungayihlukanga ngaphezu kwe-10% ngaphezulu okanye i-5.5% phantsi kobunzima bayo, babalwa besebenzisa ubude beyunithi nganye
    Ububanzi bangaphandle abuyiwa ngaphezulu kwe- ± 1% ukusuka kwibala elichaziweyo ngaphandle kwe-diameter
    Ubunzima bodonga nangayiphi na inqaku aliyi kuba ngaphezulu kwe-12,5% phantsi kobunzima obuchaziweyo
