    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

    Umbhobho weHelical Welded

    Ukuxhathisa kwi-corrosion kunye nemiba yokusingqongileyo

    Kuyo nayiphi na iprojekthi yokwakha, ixesha elide kunye nokuthembeka kwezinto eziphathekayo kubalulekile.I-S355 JR imibhobho yentsimbi ejikelezayo iyagqwesa kulo mba njengoko ixhathisa kakhulu kwi-corrosion kunye nezinto zokusingqongileyo.Intsimbi esetyenziswe kwimveliso iphathwa ngokukodwa ukunyusa ukuchasana kwayo, okwenza le mibhobho ifaneleke kuzo zombini izixhobo ezingaphezulu nangaphantsi komhlaba.Oku kuxhathisa akuqinisekisi kuphela ukuthembeka kombhobho, kodwa kwakhona kunciphisa kakhulu iindleko zokugcinwa, okwenza kube yinto ebiza imali.

    Ukwandisa uzinzo kunye ne-eco-friendly

    Ukujongana neenkxalabo zehlabathi malunga nokutshintsha kwemozulu kunye neempembelelo zokusingqongileyo, ishishini lokwakha lizama ukufuna izisombululo ezizinzileyo.S355 JRumbhobho wentsimbi ejikelezayoisebenziseka kwakhona kwaye inegalelo kule ndlela yolondolozo.Le mibhobho ingacutshungulwa kwakhona kwaye isetyenziswe kwakhona, ukunciphisa inkcitho kunye nokugcina ubutyebi bendalo.Ukongeza, ubomi babo benkonzo ende bunciphisa kakhulu isidingo sokutshintshwa, ngakumbi ukunciphisa indawo yabo yokusingqongileyo.

    Ukubambelela kwimigangatho yomgangatho ongqongqo

    I-S355 JR i-spiral steel pipe yenziwe ngononophelo ngokwemigangatho engqongqo yomgangatho.Oku kuqinisekisa ukuba umbhobho ngamnye usebenza ngokuqhubekayo kwaye uhambelana nemimiselo efunekayo yokhuseleko.Nokuba ziiprojekthi ezibalulekileyo ezinje ngemibhobho ye-oyile nerhasi okanye iziseko zothutho, le mibhobho ibonelela ngokuthembeka, ukuthembana kunye noxolo lwengqondo kwiinjineli, iikontraka kunye nabanini beeprojekthi.

    Ukuququmbela

    Ukushwankathela, i-S355 JR ipayipi yensimbi ejikelezayo ibe yinxalenye ebalulekileyo yeziseko zanamhlanje ngenxa yamandla ayo aphezulu, ubuninzi kunye nokusebenza ngokubanzi.Ulwakhiwo lwayo olomeleleyo, ukumelana nomhlwa kunye nokuthotyelwa kwemigangatho yomgangatho kwenza ukuba ilungele iiprojekthi ezahlukeneyo zokwakha.Ngaphaya koko, ukuzinza kwabo kunye nobuhlobo bendalo bongeza ixabiso kwaye negalelo kwikamva eliluhlaza.Njengoko siqhubeka nokubona ukuqhubela phambili kushishino lokwakha, kucacile ukuba i-S355 JR ipayipi yensimbi ejikelezayo iya kuqhubeka idlala indima ebalulekileyo ekubumbeni ihlabathi esiphila kulo.
