    a. Indlela yokususa ioksijini ichazwe ngolu hlobo lulandelayo:

    FF: Intsimbi ebulewe ngokupheleleyo equlethe izinto zokubopha initrogen ngobuninzi obaneleyo ukubopha initrogen ekhoyo (umz. ubuncinci be-0,020% iyonke ye-Al okanye i-0,015% ye-Al enyibilikayo).

    b. Ixabiso eliphezulu le-nitrogen alisebenzi ukuba ukwakheka kweekhemikhali kubonisa umxholo opheleleyo we-Al ongama-0,020% kunye nomlinganiselo ophantsi we-Al/N oyi-2:1, okanye ukuba kukho ezinye izinto ezaneleyo zokubopha i-N. Izinto zokubopha i-N mazirekhodwe kuXwebhu loHlolo.

    Uvavanyo lwe-Hydrostatic

    Ubude bombhobho ngamnye buya kuvavanywa ngumvelisi kuxinzelelo lwe-hydrostatic oluya kuvelisa eludongeni lombhobho uxinzelelo olungaphantsi kwama-60% wamandla aphantsi okuvelisa kubushushu begumbi. Uxinzelelo luya kugqitywa yile equation ilandelayo:
    P=2St/D

    Utshintsho Oluvumelekileyo Kubunzima Nobukhulu

    Ubude bombhobho ngamnye buya kulinganiswa ngokwahlukeneyo kwaye ubunzima bawo abuyi kwahluka ngaphezu kwe-10% ngaphezulu okanye i-5.5% phantsi kobunzima bawo obuqikelelwayo, kubalwe kusetyenziswa ubude bawo kunye nobunzima bawo ngobude beyunithi nganye.
    Ububanzi bangaphandle abuyi kwahluka ngaphezu kwe-±1% ukusuka kububanzi obuqhelekileyo bangaphandle
    Ubukhulu bodonga nangaliphi na ixesha abuyi kuba ngaphezulu kwe-12.5% ​​phantsi kobukhulu bodonga obuchaziweyo.

    Umbhobho we-Helical Welded

    1. Qonda umbhobho wentsimbi ojikelezayo we-S235 JR:

Le ndlela yokwakha inika imibhobho iingenelo ezibalulekileyo kunemibhobho yendabuko ethe tye.

    2. Iingenelo zokwakha imibhobho edibeneyo ejikelezayo:

    Ulwakhiwo lwe-S235 JR Spiral Steel Pipe oluhlanganisiweyo olujikelezileyo lubonelela ngeenzuzo ezininzi kwiinkqubo zemibhobho. Okokuqala, imithungo ye-spiral weld eqhubekekayo yonyusa ukuthembeka kwesakhiwo sembhobho, okwenza ukuba imelane kakhulu noxinzelelo lwangaphakathi nolwangaphandle. Olu lwakhiwo lukwaqinisekisa ukusasazwa komthwalo ngokulinganayo, kunciphisa umngcipheko wokungaphumeleli kombhobho. Ukongeza, imilo ye-spiral yombhobho isusa imfuneko yokuqinisa ngaphakathi, ngaloo ndlela iphucula amandla okuhamba kwamanzi kwaye inciphise ukulahleka koxinzelelo ngexesha lokudluliselwa kolwelo. Umphezulu oqhubekekayo ongenamthungo wombhobho ojikelezayo unciphisa umngcipheko wokuvuza kwaye uphucula ukhuseleko kunye nokusebenza kakuhle kwenkqubo yemibhobho.

    3. Yomeleza ukuqina kunye nokuguquguquka:

    I-S235 JR Spiral Steel Pipe inika ukuqina okuphezulu ngenxa yezixhobo zayo zokwakha ezikumgangatho ophezulu. Ziyakwazi ukumelana nokugqwala, ukukrala kunye neemeko zemozulu ezimbi kakhulu, nto leyo eyenza ukuba zilungele ukusetyenziswa ngeendlela ezahlukeneyo kuquka ukuthuthwa kweoyile negesi, iinkqubo zamanzi kunye neeprojekthi zeziseko zophuhliso. Ukuguquguquka kwezi payipi kwenza ukuba kube lula ukuzilungiselela ukuhlangabezana neemfuno ezithile zeprojekthi. Ukongeza, kulula ukuzifaka nokuzilungisa, nto leyo eyongeza ngakumbi ekuthandeni kwazo kwaye inceda ekuphuhliseni inkqubo yemibhobho esebenza kakuhle nengabizi kakhulu.

    4. Iingenelo zokusingqongileyo kunye nokuzinza:

    Ukutshintshela kwi-S235 JR spiral steel pipe kwiinkqubo zemibhobho nako kunokuzisa iingenelo ezibalulekileyo kwindalo esingqongileyo. Ubomi bayo obude kunye nokumelana nokuwohloka kunciphisa isidingo sokutshintshwa rhoqo, okubangela ukukhutshwa kwekhabhoni okuphantsi kunye nokuveliswa kwenkunkuma okuncinci. Ukongeza, ukuphindeka kwakhona kwentsimbi kwenza le mibhobho ibe lukhetho oluzinzileyo ngokuhambelana nemigaqo yezoqoqosho olujikelezayo. Ngokusebenzisa imibhobho yentsimbi ejikelezayo ye-S235 JR, amashishini anokuqinisekisa indlela enobuhlobo kwindalo esingqongileyo kunye nendlela enoxanduva yokuthutha ulwelo, ngaloo ndlela ekhuthaza ikamva eliluhlaza.
