    I-Spiral Welded Carbon Amapayipi Ensimbi Yamapayipi Egesi Yemvelo Angaphansi Komhlaba - EN10219

    I-Spiral Welded Carbon Amapayipi Ensimbi Yamapayipi Egesi Yemvelo Angaphansi Komhlaba - EN10219 Isithombe Esifakiwe
    • I-Spiral Welded Carbon Amapayipi Ensimbi Yamapayipi Egesi Yemvelo Angaphansi Komhlaba - EN10219

    Incazelo emfushane:

    Sethula ipayipi lensimbi elishiselwe okuvunguza ukuze kufakwe amapayipi egesi yemvelo angaphansi komhlaba. Leli payipi lekhwalithi ephezulu lihambisana nezindinganiso ze-EN10219 futhi linikeza uhla lwezinzuzo zezinhlobonhlobo zokusetshenziswa kwezimboni nezokuhweba.


    Imininingwane Yomkhiqizo

    Omaka bomkhiqizo

    Enye yezinzuzo eziyinhloko zeKuvunguza ashiselwe carbon steel pipeyikhono lokukhiqiza amapayipi anobubanzi obuhlukene usebenzisa imicu yobubanzi obufanayo. Lokhu kuzuzisa kakhulu izinhlelo zokusebenza ezidinga imicu emincane yensimbi ukuze kukhiqizwe amapayipi amakhulu ensimbi. Le nqubo yokukhiqiza emisha iqinisekisa ukuthi amapayipi akhiqizwayo awagcini nje kuphela futhi aqinile, kodwa futhi anekhwalithi engaguquki.

    Amapayipi ensimbi e-Spiral welded carbon aklanyelwe ngokukhethekile ukufakwa kwepayipi legesi yemvelo engaphansi komhlaba futhi ahambisana nezidingo eziqinile zeI-EN10219. Leli zinga lichaza izidingo zobuchwepheshe zokulethwa kwezingxenye ezingenalutho zesakhiwo esishiselwe okubandayo sezinsimbi ezingezona ialloyi nezinsimbi ezisanhlamvu. Ngakho-ke ipayipi lifaneleka kahle ukuthi lisetshenziswe kumapayipi egesi yemvelo angaphansi komhlaba lapho ukumelana nokugqwala kanye nobuqotho besakhiwo kubalulekile.

    a. Indlela ye-deoxidation ikhethwe kanje:

    FF: Insimbi ebulawe ngokuphelele equkethe izakhi zokubopha i-nitrogen ngamanani anele ukuhlanganisa i-nitrogen etholakalayo (isb. min. 0,020 % isiyonke i-Al noma i-0,015 % e-soluble Al).

    b. Inani eliphakeme le-nitrogen alisebenzi uma ukwakheka kwamakhemikhali kubonisa inani elincane eliphelele lokuqukethwe kwe-Al elingu-0,020 % elinesilinganiso esincane se-Al/N esingu-2:1, noma uma kukhona ezinye izakhi ezanele zokubopha i-N. Izinto ezibophezela i-N zizorekhodwa kuMqulu Wokuhlola.

    Ngaphezu kokuguquguquka kwayo ekukhiqizeni amapayipi amakhulu ensimbi, i-spiral welded carbon steel pipes inikeza ezinye izinzuzo eziningi. Ubuchwepheshe bayo be-welding obuvunguza buqinisekisa ukuthi ipayipi linendawo yangaphakathi ebushelelezi, inciphisa ukwehla kwengcindezi nokuthuthukisa izici zokugeleza. Lokhu kubaluleke kakhulu ekufakweni kwepayipi legesi yemvelo, lapho ukugeleza okuphumelelayo nokungavinjelwa kubalulekile ekusebenzeni okuhle.

    Ukwengeza, i-spiral welded carbon steel pipe imelana kakhulu nokugqwala, okuyenza ilungele ukufakwa ngaphansi komhlaba lapho ukuchayeka kumswakama nezinto zenhlabathi kungonakalisa ubuqotho bepayipi. Ukwakhiwa kwayo okuqinile nezinto ezihlala isikhathi eside kuyenza ilungele ukusetshenziswa isikhathi eside ezimweni zemvelo eziyinselele.

    Ukusetshenziswa kwe-carbon steel yekhwalithi ephezulu kuqinisekisa ukuthi amapayipi anezakhiwo ezinhle kakhulu zemishini, okuhlanganisa amandla aqinile aphezulu kanye nokumelana nomthelela. Lokhu kwenza kube ukukhetha okuthembekileipayipi legesi yemvelo elingaphansi komhlabaukufakwa, njengoba amapayipi angase abe ngaphansi kwemithwalo yangaphandle kanye nokulimala okungenzeka.

    Kafushane, amapayipi ensimbi ensimbi ayi-spiral ashiselwe ayisinqumo esingcono kakhulu sokufakwa kwepayipi legesi yemvelo engaphansi komhlaba. Inqubo yayo yokukhiqiza emisha ivumela ukukhiqizwa kwamapayipi ensimbi amakhulu amakhulu avela emigqeni emincane yensimbi, okuqinisekisa ikhwalithi engaguquki kanye nokuqina. Ipayipi lihlangabezana nezidingo zezinga le-EN10219 futhi linokumelana nokugqwala okuhle kakhulu, indawo yangaphakathi ebushelelezi kanye nezakhiwo eziqinile zemishini, okulenza lilungele ukusetshenziswa okuthembekile isikhathi eside ekufakweni kwamapayipi egesi yemvelo angaphansi komhlaba.
