    Amapayipi Ensimbi Yekhabhoni Ehlanganisiwe Ejikelezayo Yamapayipi Egesi Yemvelo Angaphansi Komhlaba - EN10219

    Amapayipi Ensimbi Yekhabhoni Ehlanganisiwe Ejikelezayo Yamapayipi Egesi Yemvelo Angaphansi Komhlaba - EN10219 Isithombe Esivelele
    • Amapayipi Ensimbi Yekhabhoni Ehlanganisiwe Ejikelezayo Yamapayipi Egesi Yemvelo Angaphansi Komhlaba - EN10219

    Incazelo emfushane:

    Kwethulwa ipayipi lensimbi yekhabhoni elihlanganisiwe eliyindilinga lokusetshenziswa kwamapayipi egesi yemvelo angaphansi komhlaba. Leli payipi lekhwalithi ephezulu lihambisana nezindinganiso ze-EN10219 futhi linikeza izinzuzo ezahlukahlukene zokusetshenziswa okuhlukahlukene kwezimboni kanye nezentengiselwano.


    Imininingwane Yomkhiqizo

    Amathegi Omkhiqizo

    Enye yezinzuzo eziyinhloko ze-ipayipi lensimbi yekhabhoni elihlanganisiwe eliyindilingayikhono lokukhiqiza amapayipi anobubanzi obuhlukene kusetshenziswa imichilo enobubanzi obufanayo. Lokhu kuzuzisa kakhulu izinhlelo zokusebenza ezidinga imichilo emincane yensimbi ukukhiqiza amapayipi ensimbi anobubanzi obukhulu. Le nqubo yokukhiqiza entsha iqinisekisa ukuthi amapayipi akhiqizwayo awagcini nje ngokuba aqinile futhi aqinile, kodwa futhi anekhwalithi efanayo.

    Amapayipi ensimbi yekhabhoni ahlanganisiwe ahlanganiswe nge-spiral aklanyelwe ngokukhethekile ukufakwa kwamapayipi egesi yemvelo angaphansi komhlaba futhi ahambisana nezidingo eziqinile zeEN10219. Leli zinga lichaza izidingo zokulethwa kobuchwepheshe zezingxenye ezingenalutho ezakhiwe ngokushintshwa okubandayo zezinsimbi ezingezona i-alloy kanye nezinsimbi ezincane. Ngakho-ke ipayipi lifaneleka kahle ukusetshenziswa kumapayipi egesi yemvelo angaphansi komhlaba lapho ukumelana nokugqwala kanye nobuqotho besakhiwo kubalulekile khona.

    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.

    Ngaphezu kokuguquguquka kwayo ekukhiqizeni amapayipi ensimbi anobubanzi obukhulu, amapayipi ensimbi yekhabhoni ahlanganisiwe anikeza ezinye izinzuzo eziningi. Ubuchwepheshe bayo bokushisela okujikelezayo buqinisekisa ukuthi ipayipi linobuso obubushelelezi bangaphakathi, okunciphisa ukwehla kwengcindezi nokuthuthukisa izici zokugeleza. Lokhu kubaluleke kakhulu ekusetshenzisweni kwamapayipi egesi yemvelo, lapho ukugeleza okusebenzayo nokungaphazanyiswa kubalulekile ekusebenzeni kahle.

    Ngaphezu kwalokho, ipayipi lensimbi yekhabhoni elihlanganisiwe eliyi-spiral limelana kakhulu nokugqwala, okwenza libe yindawo ekahle kakhulu yokufakwa ngaphansi komhlaba lapho ukuchayeka emswakama kanye nezinto zomhlabathi kungonakalisa khona ubuqotho bepayipi. Ukwakhiwa kwalo okuqinile kanye nezinto ezihlala isikhathi eside kwenza libe yindawo ekahle yokusetshenziswa isikhathi eside ezimweni zemvelo ezinzima.

    Ukusetshenziswa kwensimbi yekhabhoni esezingeni eliphezulu kuqinisekisa ukuthi amapayipi anezakhiwo ezinhle kakhulu zemishini, okuhlanganisa amandla aphezulu okudonseka kanye nokumelana nokushayisana. Lokhu kwenza kube ukukhetha okuthembekile kwe-ipayipi legesi yemvelo elingaphansi komhlabaukufakwa, njengoba amapayipi angase abe ngaphansi kwemithwalo yangaphandle kanye nomonakalo ongaba khona.

    Ngamafuphi, amapayipi ensimbi yekhabhoni ahlanganisiwe nge-spiral ayisinqumo esingcono kakhulu sokusetshenziswa kwamapayipi egesi yemvelo angaphansi komhlaba. Inqubo yayo entsha yokukhiqiza ivumela ukukhiqizwa kwamapayipi ensimbi anobubanzi obukhulu avela emicu emincane yensimbi, okuqinisekisa ikhwalithi nokuqina okuqhubekayo. Ipayipi lihlangabezana nezidingo ze-EN10219 standard futhi linokumelana okuhle kakhulu nokugqwala, ubuso bangaphakathi obubushelelezi kanye nezakhiwo eziqinile zemishini, okwenza libe yindawo ekahle yokusetshenziswa okuthembekile isikhathi eside ekufakweni kwamapayipi egesi yemvelo angaphansi komhlaba.
