    Kuvunguza amapayipi e-carbon yensimbi ye-carbon yamapayipi egesi engaphansi komhlaba - EN10219 Isithombe esifakiwe
    • Kuvunguza amapayipi e-carbon yensimbi ye-carbon yamapayipi egesi engaphansi komhlaba - EN10219

    Incazelo emfushane:

    Kwethulwa ipayipi le-spiral welded carbon yensimbi yemvelo yemvelo yamapayipi we-pipeline. Le pipeli ephezulu ihambisana namazinga we-EN10219 futhi inikezela uhla lwezinzuzo zokusetshenziswa kwezimboni ezahlukahlukene nezentengiso.


    Imininingwane Yomkhiqizo

    Amathegi Omkhiqizo

    Enye yezinzuzo eziphambili zeKuvunguza i-welded carbon steel pipeIkhono lokukhiqiza amapayipi ama-diameter ahlukene usebenzisa imichilo yobubanzi obufanayo. Lokhu kusiza ikakhulukazi izinhlelo zokusebenza ezidinga imichilo emincane yensimbi ukukhiqiza amapayipi ensimbi enkulu. Le nqubo yokukhiqiza izinto ezintsha iqinisekisa ukuthi amapayipi akhiqizwa awagcini kuphela futhi aqine, kodwa futhi nekhwalithi engaguquki.

    Amapayipi e-welded e-carbon zensimbi aklanyelwe ngokukhethekile ukufakwa kwe-pipeline yemvelo engaphansi komhlaba futhi ahambisane nezidingo eziqinile zeEn10219. Leli Zinga libonisa izidingo zokulethwa kwezobuchwepheshe ezifuywayo ezibandayo zezinhlaka ze-weldered zensimbi engeyona eye-alloy nama-steel akhiwe kahle. Ngakho-ke ipayipi lilungele ukusetshenziswa kumapayipi emvelo wemvelo lapho ukumelana nokusolwa nobuqotho bezinhlekelele bubalulekile.

    a. Indlela ye-deoxidation iqokwa kanjena:

    I-FF: Insimbi ebulewe ngokuphelele equkethe izinto ezibophayo ze-nitrogen ngamanani anele ukubopha i-nitrogen etholakalayo (isib

    b. Inani eliphakeme le-nitrogen alisebenzi uma ukwakheka kwamakhemikhali kukhombisa okuqukethwe okuphelele kwe-AL ye-AL ye-0,020% ngesilinganiso esingu-2: 1, noma uma kungenjalo ezinye izinto ezibophayo ze-N zikhona. Izinto ezibophayo ze-N-Bonding zizoqoshwa kudokhumenti lokuhlola.

    Ngokungeziwe kokuguquguqukayo kwayo ekwakheni amapayipi ensimbi amakhulu, amapayipi e-carbon e-carbon enziwe we-carbon anikela ngezinye izinzuzo eziningi. Ubuchwepheshe bayo be-welding buqinisekisa ukuthi ipayipi linokubukeka okubushelelezi kwangaphakathi, ukunciphisa ukwehla kwengcindezi kanye nokwenza ngcono ukugeleza kwezimpawu. Lokhu kubaluleke kakhulu kuzinhlelo zemvelo zegesi yemvelo, lapho ukugeleza okusebenzayo nokungahambisani kubalulekile ekusebenzeni kahle.

    Ngokwengeziwe, uSpiral Weldited Carbon Steel Pipe amelana kakhulu nokugqwala, okwenza kube kuhle ekufakweni ngaphansi komhlaba lapho ukuvezwa komswakama kanye nezinto zenhlabathi zingabeka phansi ubuqotho bepayipi. Ukwakhiwa kwayo okuqinile nezinto eziqinile zenza ilungele ukusetshenziswa kwesikhathi eside ezimweni eziyinselele zemvelo.

    Ukusetshenziswa kwensimbi esezingeni eliphakeme yekhabhoni kuqinisekisa amapayipi anezakhiwo ezinhle kakhulu zemishini, kufaka phakathi amandla aphezulu okuqina kanye nokumelana nomthelela. Lokhu kwenza kube ukukhetha okuthembekileNgaphansi komhlaba ipayipi lemvelo lemveloUkufakwa, njengoba amapayipi angaba ngaphansi kwemithamo yangaphandle kanye nomonakalo ongaba khona.

    Ngamafuphi, kuvunguza amapayipi e-carbon yensimbi e-carbon kuyinto engcono kakhulu yezicelo ezingaphansi komhlaba zegesi ye-pepeline. Inqubo yayo yokukhiqiza entsha ivumela ukukhiqizwa kwamapayipi ensimbi amakhulu kusuka emiphuzweni emincane yensimbi, eqinisekisa ikhwalithi eguqukayo nokuqina. Ipayipi lihlangabezana nezidingo ze-EN10219 standard futhi linokumelana okuhle kakhulu kokugqwala, indawo ebushelelezi yangaphakathi kanye nezindawo eziqinile zemishini, okwenza kube yinto elungele ukusetshenziswa okwethembekile okuthembekile ekufakweni kwamapayipi wemvelo wemvelo.
