    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.

    Ukuhlolwa kweHydrostatic

    Ubude bepayipi ngalinye buzovivinywa ngumenzi ngengcindezi ye-hydrostatic ezokhiqiza odongeni lwamapayipi ingcindezi engaphansi kwamandla ka-60% acacisiwe amancane okushisa avumayo ekushiseni kwegumbi. Ingcindezi izonqunywa yi-equation elandelayo:
    P = 2st / d

    Ukuhlukahluka okuvumelekile ezinsimbi nasezilinganiso

    Ubude bepayipi ngalinye buzosindwa ngokwehlukana futhi isisindo salo ngeke bahlukane ngaphezu kwe-10% ngaphezulu noma ngo-5.5% ngaphansi kwesisindo sayo sethiyori, kubalwa kusetshenziswa ubude baso kanye nesisindo sayo ngeyunithi yayo ngayinye ubude
    Ububanzi bangaphandle ngeke buhluka kakhulu kune- ± 1% kusuka kububanzi obucacisiwe be-off
    Ubukhulu bodonga nganoma yiliphi iphuzu ngeke bungabi ngaphezu kwe-12,5% ngaphansi kobukhulu bedonga olubekiwe

    Ipayipi elinohayimi

    Ukumelana nokugqwala kanye nezici zezemvelo

    Kunoma imuphi umsebenzi wokwakha, isikhathi eside nokwethembeka kwezinto zokwakha zibalulekile. I-S355 JR Spiral Steel Amapayipi Encyl kulokhu njengoba amelana kakhulu nokugqwala kanye nezici zezemvelo. Insimbi esetshenziselwa ukukhiqizwa iphathwa ngokukhethekile ukukhulisa ukumelana kwayo, okwenza la mapayipi alungele ukufakwa okungenhla- naphansi-komhlaba. Lokhu kumelana akugcini ngokuqinisekisa ubuqotho bepayipi, kepha futhi kunciphisa kakhulu izindleko zokulungiswa, okwenza kube inketho engabizi kakhulu.

    Khulisa ukuqina kanye nobungane be-eco-ubungane

    Lapho ebhekene nezinkinga zomhlaba ngokuguquguquka kwesimo sezulu nemithelela yezemvelo, imboni yezokwakha ifuna ngenkuthalo izixazululo ezizinzile. S355 jrSpiral Steel Pipeiphinde iphinde isebenze futhi inomthelela kule ndlela eqhubekayo. Lawa mapayipi angaphindiselwa futhi asetshenziswe kabusha, anciphise imfucuza kanye nokugcina izinsiza zemvelo. Ngaphezu kwalokho, impilo yabo yenkonzo ende inciphisa kakhulu isidingo sokubuyiselwa, kunciphisa futhi ukunciphisa izinyawo zabo zemvelo.

    Bambelela kumazinga aqinile asezingeni

    I-S355 JR SPLANS Steel Pipe yenziwa ngokucophelela ngokuya ngamazinga aqinile wekhwalithi. Lokhu kuqinisekisa ukuthi ipayipi ngalinye lenza ngokungaguquguquki futhi lihambisana nemithetho edingekayo yezokuphepha. Noma ngabe kumaphrojekthi abucayi afana namafutha e-oyili negesi noma ingqalasizinda yokuhamba, la mapayipi ahlinzeka ngokuthembekile, ukwethembana nokuthula kwengqondo konjiniyela, osonkontileka kanye nabanikazi bephrojekthi.

    Ekuphetheni

    Ukufingqa, i-S355 JR Spiral Steel Pipe sekuyingxenye ebalulekile yengqalasizinda yanamuhla ngenxa yamandla ayo aphakeme, ukuguquguquka nokusebenza okuphelele. Ukwakhiwa kwalo okuqinile, ukumelana nokugqwala nokuhambisana namazinga asezingeni kwenza kube kuhle kumaphrojekthi wokwakha ahlukahlukene. Ngaphezu kwalokho, ukuqina kwabo kanye nobungane be-eco-ubungane kunezela ukubaluleka futhi kufaka isandla kwikusasa eliluhlaza. Njengoba siqhubeka nokufakaza intuthuko embonini yezokwakha, kuyacaca ukuthi i-S355 JR Spiral Spiral Pipe izoqhubeka nokudlala indima ebalulekile ekubumbeni umhlaba esiphila kuwo.
