    a.Indlela ye-deoxidation yonyulwe 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.

    Iimpawu eziphezulu ze-S235 J0 ipayipi yensimbi ejikelezayo yenza ukuba ibe yinto efanelekileyo kwizicelo ezahlukeneyo.Nokuba ziiprojekthi zeshishini, zorhwebo okanye zeziseko zophuhliso, le mveliso yenzelwe ukuhlangabezana neemfuno ezingqongqo zabasebenzisi bayo.Ukusebenza kwayo okuthembekileyo kunye nokuqina kuyenza ibe sisisombululo esinexabiso eliphantsi kuyo nayiphi na iprojekthi efuna i-spiral submerged arc tubes.

    X60 SSAW Line Pipe

    Ukongeza kwi-S235 J0 ipayipi yensimbi ejikelezayo, umgca wethu wemveliso uqukaA252 Grade 3 umbhobho yentsimbi.Imveliso yenziwa kusetyenziswa itekhnoloji yokuvelisa yamva nje iqinisekisa umgangatho ophezulu kunye nemigangatho yokuthembeka.Ngokuqina kwayo okuphezulu kunye nokumelana nokugqwesa okugqwesileyo, umbhobho wentsimbi i-A252 yeBanga lesi-3 ilungele izicelo ezibango.
