    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 kakhulu 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.

    Ukuhlolwa kwe-Hydrostatic

    Ubude bepayipi ngalinye kufanele buhlolwe ngumenzi kumfutho we-hydrostatic ozokhiqiza odongeni lwamapayipi ingcindezi engekho ngaphansi kuka-60% wamandla esivuno amancane ashiwo ekamelweni lokushisa.Ingcindezi izonqunywa yi-equation elandelayo:
    P=2St/D

    Ukwehluka Okuvumelekile Kwesisindo Nobukhulu

    Ubude bepayipi ngalinye buzokalwa ngokwehlukana futhi isisindo salo angeke sihluke ngaphezu kuka-10% ngaphezulu noma u-5.5% ngaphansi kwesisindo salo esicatshangelwayo, kubalwe kusetshenziswa ubude balo nesisindo salo ngobude beyunithi ngayinye.
    Idayamitha yangaphandle akumele ihluke ngaphezu kuka-±1% ukusuka kububanzi obukhethekile obushiwo bangaphandle
    Ukujiya kodonga kunoma iyiphi indawo akufanele kube ngaphezu kuka-12.5% ​​ngaphansi kogqinsi olushiwo

    I-Helical Welded Pipe

    Imelana nokugqwala kanye nezici zemvelo

    Kunoma imuphi umsebenzi wokwakha, ukuphila isikhathi eside nokwethembeka kwezinto ezibonakalayo kubalulekile.I-S355 JR spiral steel pipes ihamba phambili kulokhu njengoba imelana kakhulu nokugqwala kanye nezici zemvelo.Insimbi esetshenziswa ekukhiqizeni iphathwa ngokukhethekile ukwandisa ukumelana kwayo, okwenza lawa mapayipi afaneleke kokubili ukufakwa okungaphezulu nangaphansi komhlaba.Lokhu kumelana akuqinisekisi kuphela ubuqotho bepayipi, kodwa futhi kunciphisa kakhulu izindleko zokulondoloza, okwenza kube inketho engabizi.

    Khulisa ukusimama kanye nobungane bemvelo

    Njengoba ibhekene nokukhathazeka komhlaba wonke mayelana nokushintsha kwesimo sezulu kanye nomthelela wemvelo, imboni yezokwakha izimisele ngokufuna izixazululo ezisimeme.I-S355 JRipayipi lensimbi elivunguzayoisebenziseka kabusha kakhulu futhi inomthelela kule ndlela esimeme.Lawa mapayipi angacutshungulwa futhi asetshenziswe kabusha, kuncishiswe ukumosha nokulondoloza imithombo yemvelo.Ukwengeza, impilo yabo yesevisi ende inciphisa kakhulu isidingo sokushintshwa, iphinde inciphise umkhondo wabo wemvelo.

    Namathela ezindinganisweni zekhwalithi eziqinile

    Ipayipi lensimbi elivunguzayo le-S355 JR lakhiwe ngokucophelela ngokuya ngezindinganiso eziqinile zekhwalithi.Lokhu kuqinisekisa ukuthi ipayipi ngalinye lisebenza ngokungaguquki futhi lihambisana nemithetho edingekayo yokuphepha.Kungakhathaliseki ukuthi amaphrojekthi abalulekile njengamapayipi kawoyela negesi noma ingqalasizinda yezokuthutha, la mapayipi ahlinzeka ngokwethembeka, ukwethenjwa nokuthula kwengqondo konjiniyela, osonkontileka nabanikazi bamaphrojekthi.

    Ekuphetheni

    Ukufingqa, ipayipi lensimbi elivunguzayo le-S355 JR seliyingxenye ebalulekile yengqalasizinda yesimanje ngenxa yamandla alo aphakeme, ukuguquguquka nokusebenza kwawo kukonke.Ukwakhiwa kwayo okuqinile, ukumelana nokugqwala kanye nokuhambisana nezindinganiso zekhwalithi kuyenza ilungele izinhlobonhlobo zamaphrojekthi wokwakha.Ngaphezu kwalokho, ukusimama kwazo kanye nobungane bemvelo kwengeza inani futhi kunomthelela ekusaseni eliluhlaza.Njengoba siqhubeka nokubona intuthuko embonini yezokwakha, kuyacaca ukuthi ipayipi lensimbi elivunguzayo i-S355 JR lizoqhubeka nokubamba iqhaza elibalulekile ekulolongeni umhlaba esiphila kuwo.
