    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.

    KwiCangzhou Spiral Steel Pipe Group Co., Ltd., siyazingca ngezakhono zethu zokuvelisa ezikumgangatho ophezulu.

    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.
