    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.

     

    Isingeniso Somkhiqizo

    Amapayipi ethu ensimbi ensimbi ayi-spiral welded carbon steel ahlangabezana nezinga le-EN10219 eliqinile, eliqinisekisa ukusebenza okuhle kakhulu nokuthembeka ezinhlobonhlobo zezinhlelo zokusebenza zezimboni nezohwebo. Akukhona nje ukuthi lawa mapayipi ekhwalithi ephezulu aqinile futhi ahlala isikhathi eside, futhi anikeza ukumelana okuhle kakhulu nokugqwala nokucindezela, okuwenza alungele ukuthutha ngokuphepha nangempumelelo igesi yemvelo ngaphansi komhlaba.

    Inqubo yokushisela okuvunguzayo eyingqayizivele ithuthukisa ubuqotho besakhiwo sepayipi, iyenze ikwazi ukumelana novivinyo lwezindawo ezinokhahlo. Ngezici zayo zokusebenza ezinhle kakhulu, ipayipi lethu le-spiral welded carbon steel lifanele uhla olubanzi lwezicelo, okuhlanganisa ukusatshalaliswa kwamandla, ukwakhiwa kanye nemiklamo yengqalasizinda.

    Ngokukhetha izinga lethu eliphezuluKuvunguza ashiselwe carbon steel pipe, utshala imali emkhiqizweni oqinisekisa impilo ende nokusebenza kahle. Ukuzinikela kwethu kukhwalithi nokwaneliseka kwamakhasimende kubonakala kuzo zonke izici zenqubo yethu yokukhiqiza, kusukela ekukhetheni izinto ezingavuthiwe kuya ekuhlolweni kokugcina.

    Inzuzo yomkhiqizo

    Enye yezinzuzo eziyinhloko zepayipi lethu le-spiral welded carbon steel linamandla alo amangalisayo nokumelana nokucindezela, okulenza libe lilungele ukuthuthwa kwegesi yemvelo ngendlela ephephile futhi ephumelelayo. Inqubo ye-welding ye-spiral ithuthukisa ubuqotho besakhiwo sepayipi, ivumela ukuba imelane nezimo zemvelo ezinzima kanye nemithwalo esindayo. Ngaphezu kwalokho, ingaphakathi elibushelelezi lepayipi linciphisa ukungqubuzana, ukwandisa izinga lokugeleza nokunciphisa ukusetshenziswa kwamandla.

    Ukushoda Komkhiqizo

    Nakuba inikeza ukusebenza okuhle kakhulu, izici ezifana nokuba sengozini yokubola kufanele zicatshangelwe, ikakhulukazi ezindaweni ezinokhahlo. Ukugqoka nokugcinwa okufanele kubalulekile ukuze kwandiswe impilo yepayipi futhi kuqinisekiswe ukwethembeka kwayo isikhathi eside. Ukwengeza, izindleko zokuqala zepayipi lensimbi yensimbi elivunguzayo elivunguvunguzayo lingaba phezulu kunezinye izinto ezisetshenziswayo, okungase kube ukucatshangelwa kwamaphrojekthi azwela isabelomali.

    Isicelo

    Amapayipi ethu ensimbi ensimbi ayi-spiral welded carbon steel ahlangabezana nezindinganiso ze-EN10219, ukuqinisekisa ukuthi izinga eliphezulu kakhulu kanye nezilinganiso zokusebenza ziyahlangatshezwa. Eklanyelwe ukumelana nezingcindezi nezinselelo zokufakwa ngaphansi komhlaba, amapayipi alungele amapayipi egesi. Ubuchwepheshe bayo obuyingqayizivele be-spiral welding abugcini nje ngokuthuthukisa ubuqotho bayo besakhiwo, kodwa futhi buhlinzeka ngokumelana okuhle kakhulu nokugqwala nokuhuzuka, okuqinisekisa ukuphila okude nokwethembeka ezimweni ezihlukahlukene zemvelo.

    Ikhabhoni yethu eyi-spiral weldedipayipi lensimbiinokusetshenziswa okunhlobonhlobo, akugcini nje ngokusetshenziswa kwegesi yemvelo. Ilungele ukusetshenziswa okuhlukahlukene kwezimboni kanye nezohwebo, okuhlanganisa izinhlelo zokuhlinzeka ngamanzi, izinhlelo zokuhlanza indle kanye nezinhlelo zokusebenza zesakhiwo. Inhlanganisela yekhwalithi ephezulu nokusebenza okuhle kwenza kube ukukhetha kokuqala konjiniyela nosonkontileka.
