    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

    Ayimelani nokugqwala kunye nezinto ezisingqongileyo

    Kuyo nayiphi na iprojekthi yokwakha, ubude bexesha kunye nokuthembeka kwezinto kubalulekile. Iipayipi zentsimbi ezijikelezayo ze-S355 JR ziyabalasela kule nkalo njengoko zimelana kakhulu nokugqwala kunye nezinto ezingqongileyo. Intsimbi esetyenziswa kwimveliso iphathwa ngokukodwa ukwandisa ukumelana kwayo, okwenza le mibhobho ifaneleke zombini ukufakwa ngaphezulu nangaphantsi komhlaba. Olu xhathiso aluqinisekisi nje kuphela ukuthembeka kombhobho, kodwa lukwanciphisa kakhulu iindleko zokugcinwa, nto leyo eyenza ukuba ibe lukhetho olungabizi kakhulu.

    Ukwandisa uzinzo kunye nobuhlobo nokusingqongileyo

    Lijongene neenkxalabo zehlabathi malunga notshintsho lwemozulu kunye nefuthe lokusingqongileyo, ishishini lokwakha lizama ngenkuthalo izisombululo ezizinzileyo. S355 JRumbhobho wentsimbi ejikelezayoiphinda isetyenziswe kakhulu kwaye inegalelo kule ndlela izinzileyo. Le mibhobho inokuphinda isetyenziswe kwaye isetyenziswe, inciphisa inkunkuma kwaye ilondoloze izixhobo zendalo. Ukongeza, ubomi bayo obude benkonzo bunciphisa kakhulu isidingo sokutshintshwa, nto leyo enciphisa ngakumbi umngcipheko wayo kwindalo esingqongileyo.

    Landela imigangatho engqongqo yomgangatho

    Umbhobho wentsimbi ojikelezayo we-S355 JR wenziwa ngononophelo ngokwemigangatho engqongqo yomgangatho. Oku kuqinisekisa ukuba umbhobho ngamnye usebenza ngokuhambelanayo kwaye uhambelana nemigaqo yokhuseleko efunekayo. Nokuba ziiprojekthi ezibalulekileyo ezifana nemibhobho yeoyile negesi okanye iziseko zothutho, le mibhobho inika ukuthembeka, ukuthembana kunye noxolo lwengqondo kwiinjineli, abakhi kunye nabanini beprojekthi.

    Ukuququmbela

    Ngamafutshane, umbhobho wentsimbi ojikelezayo we-S355 JR ube yinxalenye ebalulekileyo yeziseko zophuhliso zanamhlanje ngenxa yamandla awo aphezulu, ukuguquguquka kwawo kunye nokusebenza kwawo ngokubanzi. Ukwakhiwa kwawo okuqinileyo, ukumelana nokugqwala kunye nokuthobela imigangatho yomgangatho kuyenza ifaneleke kwiiprojekthi ezahlukeneyo zokwakha. Ngaphezu koko, ukuzinza kwawo kunye nobuhlobo nokusingqongileyo kongeza ixabiso kwaye kunegalelo kwikamva eliluhlaza. Njengoko siqhubeka nokubona inkqubela phambili kushishino lokwakha, kuyacaca ukuba umbhobho wentsimbi ojikelezayo we-S355 JR uza kuqhubeka nokudlala indima ebalulekileyo ekubumbeni ihlabathi esiphila kulo.
