    Imibhobho yentsimbi ejikelezayo ye-ASTM A139 S235 J0 Umfanekiso obonisiweyo
    • Imibhobho yentsimbi ejikelezayo ye-ASTM A139 S235 J0

    Inkcazo emfutshane:

    Sizisa ubuchule bethu bamva nje kwitekhnoloji yemibhobho yentsimbi – i-S235 J0 Spiral Steel Pipe. Le mveliso yenzelwe ukusebenzisaI-ASTM A139 imigangatho yokuqinisekisa ulwakhiwo olusemgangathweni ophezulu kunye nokusebenza. Inkqubo yokwenza umbhobho wentsimbi ejikelezayo esetyenziswa ekuvelisweni kwayo iqinisekisa ukuguquka okufanayo kwepleyiti yentsimbi, uxinzelelo oluncinci olushiyekileyo, kunye nomphezulu ogudileyo ongenamikrwelo.


    Iinkcukacha zeMveliso

    Iithegi zeMveliso

    Enye yezona nzuzo ziphambili zeUmbhobho wentsimbi ojikelezayo we-S235 J0bukuguquguquka kwayo ngobukhulu bayo kunye neenkcukacha zobukhulu bodonga. Oku kuvumela ukuba imveliso ikwazi ukuguquguquka ngakumbi, ingakumbi ekuvelisweni kwemibhobho enodonga oluqinileyo, ekumgangatho ophezulu. Ukongeza, le teknoloji isebenza kakuhle kakhulu ekuvelisweni kwemibhobho enodonga oluqinileyo enobubanzi obuncinci nobuphakathi, iphumelela ngaphezu kwezinye iindlela ezikhoyo.

    a. Indlela yokususa i-oxidation ichazwe ngolu hlobo lulandelayo: FF: Intsimbi ebulewe ngokupheleleyo equlethe izinto zokubopha i-nitrogen ngobuninzi obaneleyo ukubopha i-nitrogen ekhoyo (umz. ubuncinci be-0,020 % iyonke ye-Al okanye i-0,015 % ye-Al enyibilikayo).b. Ixabiso eliphezulu le-nitrogen alisebenzi ukuba ulwakhiwo lweekhemikhali lubonisa umxholo we-Al ophantsi we-0,020 % kunye nomlinganiselo ophantsi we-Al/N we-2:1, okanye ukuba kukho ezinye izinto zokubopha i-N ezaneleyo. Izinto zokubopha i-N mazirekhodwe kwiXwebhu loHlolo.

    Iimpawu ezigqwesileyo zombhobho wentsimbi ojikelezayo we-S235 J0 zenza ukuba ilungele ukusetyenziswa ngeendlela ezahlukeneyo. Nokuba ziiprojekthi zoshishino, zorhwebo okanye zeziseko zophuhliso, le mveliso yenzelwe ukuhlangabezana neemfuno ezingqongqo zabasebenzisi bayo. Ukusebenza kwayo okuthembekileyo kunye nokuqina kwayo kwenza ukuba ibe sisisombululo esingabizi kakhulu kuyo nayiphi na iprojekthi efuna iityhubhu ze-arc eziphantsi komhlaba ezijikelezayo.

    Umbhobho woMgca we-X60 SSAW

    Ukongeza kumbhobho wentsimbi ojikelezayo we-S235 J0, umgca wethu wemveliso ukwaqukaUmbhobho wentsimbi weBanga lesi-3 we-A252Le mveliso yenziwe kusetyenziswa ubuchwepheshe bamva nje bokuvelisa obuqinisekisa umgangatho ophezulu kunye nemigangatho yokuthembeka.
