    a. Indlela ye-deoxidation yonyulwa ngolu hlobo lulandelayo:

    FF: Intsimbi ebulewe ngokupheleleyo equlethe izinto ezibophelelayo zenitrogen ngokwezixa ezaneleyo zokubopha initrogen ekhoyo (umz. min. 0,020 % iyonke iAl okanye i-0,015 % enyibilikayo iAl).

    b. Ixabiso eliphezulu le-nitrogen alisebenzi ukuba ukubunjwa kweekhemikhali kubonisa ubuncinane be-Al umxholo we-0,020 % kunye nomlinganiselo we-Al/N ubuncinane we-2: 1, okanye ukuba kukho ezinye izinto ezaneleyo ze-N-binding. Izinto ezibophelelayo ze-N ziya kubhalwa kuXwebhu loHlolo.

    Uvavanyo lweHydrostatic

    Ubude bombhobho ngamnye buya kuvavanywa ngumenzi kuxinzelelo lwe-hydrostatic oluya kuvelisa eludongeni lombhobho uxinzelelo olungekho ngaphantsi kwama-60% obona buncinci buchaziweyo bamandla esivuno kwindawo yobushushu begumbi. Uxinzelelo luya kumiselwa ngolu nxaki lulandelayo:
    P=2St/D

    Ukwahluka okuvumelekileyo kubunzima kunye nemilinganiselo

    Ubude bombhobho ngamnye buya kulinganiswa ngokwahlukeneyo kwaye ubunzima bawo abuyi kwahluka ngaphezu kwe-10% ngaphezulu okanye i-5.5% phantsi kobunzima bethiyori, kubalwe kusetyenziswa ubude bayo kunye nobunzima bayo ngeyunithi yobude.
    Idayamitha yangaphandle ayisayi kwahluka ngaphezu kwe-±1% ukusuka kwidayamitha yangaphandle echaziweyo
    Ubunzima bodonga nakweyiphi na indawo abuyi kuba ngaphezu kwe-12.5% ​​phantsi kobukhulu bodonga oluchaziweyo

    I-S235 J0 iSpiral Steel Pipe

     

    Enye yezinto ezibalaseleyo ze-S235 J0 Spiral Steel Tube kukuguquguquka kwayo. Ifumaneka kwiifom ezijikelezileyo, zesikwere kunye noxande, imveliso inokwenziwa ngokwezifiso ukuze ihambelane neemfuno ezithile zeprojekthi. Nokuba wakha isakhelo esomeleleyo sesakhiwo sorhwebo, udala uyilo oluntsonkothileyo lwembonakalo yoyilo, okanye uphuhlisa iziseko ezingundoqo ezinje ngeebhulorho kunye neetonela, i-S235 J0 Spiral Steel Tube ibonelela ngokuguquguquka kunye namandla afunekayo ukuze ufezekise umbono wakho.

    Ukutyunjwa kwe-S235 kubonisa ukuba ityhubhu yenziwe kwintsimbi yesakhiwo kunye ne-weldability egqwesileyo kunye nokuguquguquka. Oku kubaluleke ngakumbi kwiiprojekthi ezifuna ukwenziwa ngokuchanekileyo kunye nokudibanisa. Isimamva se-J0 sibonisa ukuba izinto eziphathekayo ziyakwazi ukumelana nokushisa okuphantsi, okwenza ukuba zilungele ukusetyenziswa kwiindawo ezinzima apho ukuguquka kweqondo lokushisa kunokubeka ingozi kwingqibelelo yesakhiwo. Olu luhlu lweepropati luqinisekisa ukuba i-S235 J0 ityhubhu yensimbi ye-spiral ayithembekanga kuphela, kodwa iyakwazi ukumelana noluhlu olubanzi lweemeko zemozulu.

    Ukongeza, ubume obubandayo be-S235 J0 umbhobho wentsimbi ejikelezayo unika umphezulu ogqwesileyo wokugqiba kunye nokuchaneka komda. Oku kuthetha ukuba umbhobho unokuhlanganiswa ngokulula kwiinkqubo ezikhoyo ngaphandle kokuguqulwa okubanzi. Umphezulu ogudileyo uphinda uphucule ubuhle bemveliso yokugqibela, okwenza kube lukhetho oluphezulu lwabakhi bezakhiwo kunye nabaqulunqi abaxabisa ukusebenza kunye neempembelelo ezibonakalayo.

    imibhobho yentsimbi ejikelezayo

    Ukongeza kwiinzuzo zayo zobugcisa, i-S235 J0 ipayipi yensimbi ejikelezayo nayo ikhethwa ngokusingqongileyo. Inkqubo yokwenziwa kwemveliso inciphisa inkcitho kunye nokusetyenziswa kwamandla, ngokuhambelana nentsingiselo ekhulayo yozinzo kushishino lokwakha. Ngokukhetha le mveliso, awugcini nje utyalo-mali kumgangatho, kodwa uphinde ube negalelo kwikamva eliluhlaza.

    Kuzo zonke, i-S235 J0 Spiral Steel Tube sisisombululo esisingqinisiso esidibanisa ngokugqibeleleyo amandla, ubuninzi kunye nokuzinza. Nokuba uqalisa iprojekthi yokwakha entsha okanye ujonge ukomeleza isakhiwo esele sikhona, le mveliso yenzelwe ukuhlangabezana kunye nokugqithisa okulindelekileyo. Ukuthobela imigangatho yaseYurophu kunye neempawu zokusebenza ezigqwesileyo, i-S235 J0 Spiral Steel Tube lolona khetho lufanelekileyo kwiinjineli, abakhi bezakhiwo kunye nabakhi abafuna ezona zinto zintle kwizinto zokwakha. Yamkela ikamva lolwakhiwo kunye ne-S235 J0 Spiral Steel Tube - indibaniselwano yezinto ezintsha kunye nokuthembeka.
