    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 wentsimbi ejikelezayo ye-S235 J0

     

    Enye yezona zinto zibalaseleyo kwi-S235 J0 Spiral Steel Tube kukuguquguquka kwayo.

    Igama le-S235 libonisa ukuba ityhubhu yenziwe ngentsimbi yokwakha enobuxhakaxhaka obuhle bokudityaniswa kunye noomatshini. Oku kubaluleke kakhulu kwiiprojekthi ezifuna ukwenziwa ngokuchanekileyo kunye nokuhlanganiswa. Isimamva se-J0 sibonisa ukuba izinto zinokunyamezela amaqondo obushushu aphantsi, nto leyo eyenza ukuba zifaneleke ukusetyenziswa kwiindawo ezinzima apho ukuguquguquka kwamaqondo obushushu kunokubangela umngcipheko kwisakhiwo. Olu dibaniso lweempawu luqinisekisa ukuba ityhubhu yentsimbi ye-S235 J0 ayithembekanga nje kuphela, kodwa ikwakwazi ukumelana neemeko ezahlukeneyo zemozulu.

    Ukongeza, indlela ebanda ngayo ipayipi yentsimbi ejikelezayo ye-S235 J0 iyenza ibe nomphezulu ogqwesileyo kunye nokuchaneka okulinganayo. Oku kuthetha ukuba ipayipi inokudityaniswa ngokulula kwiinkqubo ezikhoyo ngaphandle kotshintsho olukhulu. Umphezulu ogudileyo ukwaphucula ubuhle bemveliso yokugqibela, okwenza ibe lukhetho oluphezulu kubayili bezakhiwo kunye nabayili abaxabisa ukusebenza kunye nempembelelo ebonakalayo.

    imibhobho yentsimbi ejikelezayo

    Ukongeza kwiingenelo zayo zobugcisa, umbhobho wentsimbi ojikelezayo we-S235 J0 ukwayindlela enobuhlobo nokusingqongileyo. Inkqubo yokuvelisa inciphisa ukusetyenziswa kwenkunkuma kunye namandla, ngokuhambelana nomkhwa okhulayo wokuzinza kwishishini lokwakha. Ngokukhetha le mveliso, awutyali nje kuphela umgangatho, kodwa ukwanegalelo kwikamva eliluhlaza.

    Lilonke, i-S235 J0 Spiral Steel Tube sisisombululo esiphambili esidibanisa ngokugqibeleleyo amandla, ukuguquguquka kunye nokuzinza.
